If an ideal gas is compressed isothermally then
If an ideal gas is compressed isothermally then
If an ideal gas is compressed isothermally then
When an ideal gas is compressed adiabatically, its temperature rises: the molecules on the average have more kinetic energy than before. The kinetic energy increases, [1]
When an ideal gas is compressed adiabatically, its temperature rises: the molecules on the average have more kinetic energy than before. because of collisions with moving parts of the wall only.
because of redistribution of energy amongst the molecules.. because the molecules get accelerated in their motion inside the volume.
The collisions between the ideal gas molecules and the moving part of the wall is elastic, therefore kinetic energy of the molecules colliding with it increases.. Since the compression is done adiabatically, the work done on the gas increases kinetic energy of the molecules
When an ideal gas is compressed isothermally then its pressure increases becauseA. Its potential energy decreases,B. Its kinetic energy increases and molecules move apart.C. Its number of collisions p [2]
When an ideal gas is compressed isothermally then its pressure increases because. Its kinetic energy increases and molecules move apart.
Hint: We are given an isothermal situation where an ideal gas is compressed. We know that when we compress a gas the volume of the gas gets decreased due to which the area also decreases
In the question it is said that when we compress an ideal gas isothermally, the pressure will increase. We are asked what causes the pressure to increase in such a situation.
When a gas is compressed keeping the temperature constant it results in [3]
When a gas is compressed keeping the temperature constant it results in. The molecular theory states that the pressure exerted by a gas in a closed vessel results from the gas molecules stiking against the walls of the vessel
[Solved] When an ideal gas is pressed at constant temperature, which [4]
When an ideal gas is pressed at constant temperature, which of the following remains constant?. – Internal energy: It refers to the total (kinetic and potential) energy of the particles of a given system.
– So, the internal energy of an ideal gas is purely its kinetic energy.. – From the kinetic theory of gas, the temperature of a gas is directly proportional to the average kinetic energy of its particles.
– Therefore, there will be no change in the kinetic energy and thus, no change in the internal energy of the gas.. The written exam will be held on 3rd September 2023

An ideal gas at $300 \mathrm{K}$ is compressed isothermally to one-fifth its original volume. Calculate the change in the entropy for a process in which 2 moles of an ideal gas undergoes a free expansion to three times its initial volume
So we need to find this so as we know that the change in the entropy is given by a change in heat divided by the temperature right and change in temperature is given, as n into r into t multiplied by log of base and of final…

3.6 Adiabatic Processes for an Ideal Gas – University Physics Volume 2 [7]
– Demonstrate the qualitative difference between adiabatic and isothermal expansions. When an ideal gas is compressed adiabatically work is done on it and its temperature increases; in an adiabatic expansion, the gas does work and its temperature drops
Nevertheless, because work is done on the mixture during the compression, its temperature does rise significantly. In fact, the temperature increases can be so large that the mixture can explode without the addition of a spark
Another interesting adiabatic process is the free expansion of a gas. Figure 3.13 shows a gas confined by a membrane to one side of a two-compartment, thermally insulated container

Adiabatic process [9]
In thermodynamics, an adiabatic process (Greek: adiábatos, “impassable”) is a type of thermodynamic process that occurs without transferring heat or mass between the thermodynamic system and its environment. Unlike an isothermal process, an adiabatic process transfers energy to the surroundings only as work.[1][2] As a key concept in thermodynamics, the adiabatic process supports the theory that explains the first law of thermodynamics.
In meteorology and oceanography, adiabatic cooling produces condensation of moisture or salinity, oversaturating the parcel. There, the process becomes a pseudo-adiabatic process whereby the liquid water or salt that condenses is assumed to be removed upon formation by idealized instantaneous precipitation
A process without transfer of heat to or from a system, so that Q = 0, is called adiabatic, and such a system is said to be adiabatically isolated.[5][6] The simplifying assumption frequently made is that a process is adiabatic. For example, the compression of a gas within a cylinder of an engine is assumed to occur so rapidly that on the time scale of the compression process, little of the system’s energy can be transferred out as heat to the surroundings

What happens to the temperature when an ideal gas is compressed? [11]
I know from Charles’ law that under constant pressure, the volume of a gas is directly proportional to its absolute temperature i.e.. Thus accordingly, during compression, temperature of the gas would decrease
Suppose that the piston moves inward, so that the atoms are slowly compressed into a smaller space. What happens when an atom hits the moving piston? Evidently it picks up speed from the collision
Therefore all the atoms which are in the vessel will have picked up speed. This means that when we compress a gas slowly, the temperature of the gas increases.
