What happens to the volume of gas in a cylinder with a movable piston when the absolute temperature is halved, and the external pressure on the piston doubles. The volume increases by 25% The volume remains the same O The volume is doubled The volume is halved The volume decreases by 75% A process occurs under conditions where no work can be done by or on the surroundings. The energy of the surroundings increases during this process. Which statement about the system is correct? The system is undergoing an exothermic process The system is undergoing an endothermic process The internal energy of the system is increasing The heat capacity of the system is decreasing The enthalpy of the system is increasing
