A process that occurs while the pressure remains constant is referred to as

• adiabatic process

• constant-volume process

• constant-pressure process

• isothermal process

In an adiabatic process, if work is done on a system (W < 0), then the system thermal energy

• increases

• decreases

• stay same

• no change

In an adiabatic system, If a system does work (W > 0), then its thermal energy

• increases

• decreases

• no change

• stay same

• freezing

• radiation

• equilibrium

When a gas expands adiabatically,

• the internal (thermal) energy of the gas decreases

• the internal (thermal) energy of the gas increases

• it does no work

• work is done on the gas
