The concentration inside the cell is greater than outside. The concentration is the same inside and outside the cell
The concentration inside the cell is greater than outside describes a cell after diffusion. Therefore, the correct option is option A among all the given options.What is diffusion?
It is the primary mode of transport for vital chemicals (such as amino acids) between cells. It is necessary for the production of energy via respiration and photosynthesis.

The Physics Classroom Tutorial [4]
If you have been following along since the beginning of this lesson, then you have been developing a progressively sophisticated understanding of temperature and heat. You should be developing a model of matter as consisting of particles which vibrate (wiggle about a fixed position), translate (move from one location to another) and even rotate (revolve about an imaginary axis)
The more the particles vibrate, translate and rotate, the greater the temperature of the object. You have hopefully adopted an understanding of heat as a flow of energy from a higher temperature object to a lower temperature object
The heat transfer continues until the two objects have reached thermal equilibrium and are at the same temperature. The discussion of heat transfer has been structured around some everyday examples such as the cooling of a hot mug of coffee and the warming of a cold can of pop
Heat transfer [5]
Heat transfer is a discipline of thermal engineering that concerns the generation, use, conversion, and exchange of thermal energy (heat) between physical systems. Heat transfer is classified into various mechanisms, such as thermal conduction, thermal convection, thermal radiation, and transfer of energy by phase changes
While these mechanisms have distinct characteristics, they often occur simultaneously in the same system.. Heat conduction, also called diffusion, is the direct microscopic exchanges of kinetic energy of particles (such as molecules) or quasiparticles (such as lattice waves) through the boundary between two systems
Such spontaneous heat transfer always occurs from a region of high temperature to another region of lower temperature, as described in the second law of thermodynamics.. Heat convection occurs when the bulk flow of a fluid (gas or liquid) carries its heat through the fluid
13.1 Heating as a transfer of energy [6]
When the Bunsen burner is lit, what happens to the rod just above it?. Energy is transferred to the metal of the rod just above it
In the last chapter we looked at thermal systems which transfer energy. This chapter expands on this and looks at the different ways that thermal energy is transferred between different objects.
Temperature is a measure of how hot or cold an object is; it is a measure of the average kinetic energy of the particles of a substance. Heat is the energy transferred between two objects as a consequence of the temperature difference between them
1.2.1 Energy Transfers in a System (GCSE Physics AQA) [7]
Energy – 1.2.1 Energy Transfers in a System (GCSE Physics AQA). The conservation of energy is an important principle in Physics
Energy can be transferred usefully, stored or dissipated, but cannot be created or destroyed.. Since we know that energy cannot be created or destroyed, all the energy from a system must be dissipated somehow
In many energy transfers, thermal energy is a waste product. For example, when we switch on a light bulb, chemical energy is being transferred to light energy, but some of the energy will be ‘wasted’ as thermal energy.
Section B: Energy Transfer – Energy Education: Concepts and Practices [8]
The two ways that energy can be transferred are by doing work and by heat transfer.. Energy can be transferred from one object to another by doing work
When work is done, energy is transferred from the agent to the object, which results in a change in the object’s motion (more specifically, a change in the object’s kinetic energy).. An Example of How Doing Work Transfers Energy from One Object to Another
Recall that the work done on the wheelbarrow by the person is equal to the product of the person’s force multiplied by the distance traveled by the wheelbarrow. Notice that when the force is exerted on the wheelbarrow, there’s a change in its motion
– Calculate the increase of entropy in a system with reversible and irreversible processes.. – Explain the expected fate of the universe in entropic terms.
By examining it, we shall see that the directions associated with the second law—heat transfer from hot to cold, for example—are related to the tendency in nature for systems to become disordered and for less energy to be available for use as work. The entropy of a system can in fact be shown to be a measure of its disorder and of the unavailability of energy to do work.
Entropy is a measure of how much energy is not available to do work. Although all forms of energy are interconvertible, and all can be used to do work, it is not always possible, even in principle, to convert the entire available energy into work
12.2 First law of Thermodynamics: Thermal Energy and Work [10]
By the end of this section, you will be able to do the following:. – Describe how pressure, volume, and temperature relate to one another and to work, based on the ideal gas law
– Solve problems involving the first law of thermodynamics. |Boltzmann constant||first law of thermodynamics||ideal gas law|
Pressure, Volume, Temperature, and the Ideal Gas Law. Before covering the first law of thermodynamics, it is first important to understand the relationship between pressure, volume, and temperature
Heat Transfer in Health and Healing [11]
Our bodies depend on an exquisitely sensitive and refined temperature control system to maintain a state of health and homeostasis. The exceptionally broad range of physical activities that humans engage in and the diverse array of environmental conditions we face require remarkable strategies and mechanisms for regulating internal and external heat transfer processes
The focus of human thermoregulation is maintenance of the body core temperature within a tight range of values, even as internal rates of energy generation may vary over an order of magnitude, environmental convection, and radiation heat loads may undergo large changes in the absence of any significant personal control, surface insulation may be added or removed, all occurring while the body’s internal thermostat follows a diurnal circadian cycle that may be altered by illness and anesthetic agents. An advanced level of understanding of the complex physiological function and control of the human body may be combined with skill in heat transfer analysis and design to develop life-saving and injury-healing medical devices
Humans are able to survive exposure to a remarkably broad range of environmental thermal stressors and to alterations in the distribution and magnitude of internal energy generation, all while maintaining a nearly constant core temperature necessary for health and well being. The thermoregulatory system consists of thermal sensors and diverse actuators located throughout the body
Heat, Temperature, and Conduction [12]
Are you loving this? Not loving this? Please consider taking a moment to share your feedback with us. – Adding energy (heating) atoms and molecules increases their motion, resulting in an increase in temperature.
– Energy can be added or removed from a substance through a process called conduction.. – In conduction, faster-moving molecules contact slower-moving molecules and transfer energy to them.
– Temperature is a measure of the average kinetic energy of the atoms or molecules of a substance.. – Heat is the transfer of energy from a substance at a higher temperature to a substance at a lower temperature.
Heat Transfer: No Magic About It – Lesson [13]
SummaryHeat transfer is an important concept that is readily evident in our everyday lives yet often misunderstood by students. In this lesson, students learn the scientific concepts of temperature, heat, and heat transfer through conduction, convection and radiation
Heat is a concept that is important to understand in various engineering fields. It is particularly relevant for civil, mechanical and chemical engineers because heat transfer plays a key role in material selection, machinery efficiency and reaction kinetics, respectively
– Define and explain heat, conduction, convection and radiation.. – Explain the relationship between the kinetic and potential energy of atoms in a thermodynamic system.
