2. A gaseous system absorbs 43 J of heat and increases its internal energy by 64 J. Which of the following statements is correct? The volume of the system increases and a negative amount of work is done. The volume of the system decreases and a negative amount of work is done.

The change in internal energy of a system (ΔE) can be described in terms of heat (q) and work (w) according to the equation ΔE = q + w. The conversion of 40 g of liquid H2O to steam at 1.0 atm leads to an increase in its volume. This expansion exerts 4.545 kJ of work on the surroundings. If the increase in internal energy of the H2O is 85.724 kJ, how much heat energy does this vaporization process use?...

Which of these statements are true? -The internal energy of any gas depends only the temperature of the system. - The internal energy of a gas always increases with temperature -The heat capacity of a monoatomic ideal gas is always smaller than the heat capacity of a polyatomic ideal gas. - q = 0 for any process that does not result in a change in temperature.

Which of the following statements about pressure-volume work is true? The reversible process provides the maximum amount of work. Work done at constant-pressure is zero. When work is done on the system in an adiabatic process there is a decrease in the internal energy of the system. Changes in pressure-volume work must always be offset by changes in the heat of the system. A free expansion takes place against a constant external pressure of 1 bar.
