Video answer: A gas expands with a constant temperature ## Top best answers to the question «What happens when gas expands at constant temperature»

It is correct because at constant temperature kinetic energy of the gas remains the same. Therefore, if gas expands at a constant temperature the kinetic energy of the molecules remains the same… If the temperature of the gas increases the kinetic energy of the gas also increases.

How does the temperature of gas change when it is compressed when it expands? When gas is compressed, the temperature increases. expands, the temperature decreases.The temperature of gas increases...

As the volume of a gas expands, the overall temperature tends to drop because there are fewer molecules per any given volume. If properly balanced, you could supply heat for expansion at a rate that maintains a constant temperature. For this particular problem though, the only option that fits is C. How close am I?

If a gas expands at constant temperature, then, by definition of temperature the kinetic energy remains constant. We find this happens in the absence of containment. If the molecules do zero work in expanding into a vacuum with no containment field then all of the molecules retain their kinetic energy after the last collision with another molecule.

Hence, at the constant temperature, the kinetic energy remains same. Thus during expansion of a gas at constant temperature, the kinetic energy of gas molecules remains same. Hence, option (B) is correct and option (C) is incorrect. The number of molecules of gas is not affected by the expansion or compression of a gas.

What happens to the volume of a gas as it is heated? This law states that the volume and temperature of a gas have a direct relationship: As temperature increases, volume increases, when pressure is held constant. Heating a gas increases the kinetic energy of the particles, causing the gas to expand.

kinetic energy of molecules remains same. If a gas expands at a constant temperature, it indicates that the kinetic energy of molecules remains the same. The average kinetic energy of a gas molecule is given by the expression: K.E = 23. .

3. As gas particles expand into a vacuum there's no transfer of their kinetic energy into anything else, they do not collide with anything but with themselves. Since the temperature of a gas is a measure of the average kinetic energy of its particles, the temperature remains constant.

When an ideal gas expands at constant temperature, we need to add heat in order for the internal energy to stay the same. This is an isothermal process, as seen below. When an ideal gas expands at constant pressure, known as an isobaric process, we need to add heat in order to keep the pressure constant while we are expanding, as seen below.

This shows the expansion of gas at constant temperature against weight of an object's mass (m) on the piston. Temperature is held constant, therefore the change in energy is zero (U=0). So, the heat absorbed by the gas equals the work done by the ideal gas on its surroundings. Enthalpy change is also equal to zero because the change in energy zero ...
