In an isothermal process, you are told that heat is being added to the system. Which of the following is nottrue?

of an ideal gas expands at a constant temperature of . If of energy is inputted into the system and the net change of internal energy , by what factor does the volume of the gas change?

of an ideal gas is at a pressure of . If of heat is transferred to the gas as it expands at a constant pressure of , what is the change in internal energy of the gas?

Which of the following is not one of the laws of thermodynamics?

A piston alters the gas held in a sealed chamber. If of heat is added to the system when the piston compresses at a constant force of , what is the change in internal energy of the system?

If the isothermal expansion of a gas inside a container absorbs 25 kJ of heat energy, how much work is done by the gas in this process?
