Gas is a loosely bound group of molecules that have changed phase from solid to liquid to gas through an increase in thermal energy. Once it has reached the gas phase, heating gas can increase its temperature because the energy will not go into the potential energy of a phase change, but instead the kinetic energy of phase change.

Joule Thomson effect is temperature dependent or not?
The Joule-Thomson effect is temperature dependent. It describes the change in temperature of a gas as it expands or is compressed without doing external work. If the gas undergoes adiabatic expansion (no heat exchange with surroundings), its temperature will change depending on its initial temperature, pressure, and the nature of the gas.
Does gas have a definite volume and can change volume?
does gas take the shape of it's container and can change volume
What is the relationship between enthalpy and temperature change during an adiabatic expansion process?
During an adiabatic expansion process, there is no heat exchange with the surroundings. As a result, the change in enthalpy is directly related to the change in temperature. When a gas expands adiabatically, its temperature decreases, leading to a decrease in enthalpy.
Why can gasses change volume (apex)?
That's because they are quite easily compressible. There are no forces holding the gas particles together. (apex)
When an ideal gas expands in vacuum work done is?
When an ideal gas expands in a vacuum, no work is done because there is no external pressure against which the gas can expand. In this case, the expansion is considered to be isentropic, meaning that there is no change in entropy of the system.
Joule Thomson effect is temperature dependent or not?
The Joule-Thomson effect is temperature dependent. It describes the change in temperature of a gas as it expands or is compressed without doing external work. If the gas undergoes adiabatic expansion (no heat exchange with surroundings), its temperature will change depending on its initial temperature, pressure, and the nature of the gas.
Which of the gas properties will change?
When a gas is compressed, its volume will decrease, its pressure will increase, and its temperature may increase.
Why do balloons expands when its temperature increases?
Balloons are filled with gas and gas expands when temperature increases. Gas also condenses when the temperature is lowered. This is due to Charles' law.
What results from increasing the temperature of a gas?
The gas expands.
What is the principle of the gas thermometer?
The principle of a gas thermometer is based on the relationship between the volume of gas and its temperature. As the gas temperature increases, its volume expands proportionally. By measuring this volume change, the temperature of the gas inside the thermometer can be determined.
Why do compressed air get cold when released from a container?
When compressed air is released from a container, it expands rapidly, causing a drop in temperature due to the gas molecules losing energy as they spread out. This phenomenon is known as the Joule-Thomson effect.
What happens to the temperature of a gas that is squeezed or compressed?
If you compress a gas the temperature increases
Is freon a solid liquid or a gas?
It could be any of the three but at room temperature it is a gas. Freon is a gas
What happen when a gas is cool?
A change in temperature will change its properties, like from gaseous form to liquid form for example.
How does the temperature of gas change when it is compressed if the process is adiabatic?
In an adiabatic process, the temperature is increased when it is compressed. There is an increase in internal kinetic energy, and because temperature is related to kinetic energy, it is also increased.
Why water expand when it losses heat to turn into ice?
Th water on your body evaporates into the air and since evaporation ... You can experience temperature change due to compression by examining a can of ... your body it feels very cold because the compressed gas expands and loses heat.
Why can the vulume of a gas change and the solid of a remain constaant?
In a solid,particles are packed tightly to each other while the gas particles are not packed tightly. So the gas particles can be compressed and can change the volume. Solids cannot be compressed to change the volume.
