A)The gas must absorb heat from its surroundings.
B)The gas must release heat to its surroundings.
C)The pressure of the gas also stays constant.
D)The process is adiabatic.
E)It is impossible to predict on the basis of this data.

As the temperature of the gas is kept constant during the compression process, the gas cannot absorb energy in the form of heat from its surroundings. Therefore, it must release energy in the form of heat to its surroundings. This energy release is necessary to maintain a constant temperature while the gas is being compressed. Choice A is incorrect for this reason. Choice C is also incorrect, as the pressure of the gas is increasing due to the compression process. Choice D is incorrect, as the process is not adiabatic if heat energy is being transferred between the gas and its surroundings. Choice E is not correct, as the information provided is sufficient to make a determination about the behavior of the gas during this process.
