Measurements show that the energy of a mixture of gaseous reactants increases by 264 KJ during a certain chemical reaction, which is carried out at a constant pressure. Furthermore, by carefully monitoring the volume change it is determined that 82 KJ of work is done on the mixture during the reaction. Calculate the change in enthalpy of the gas mixture during the reaction.

An arctic weather balloon is filled with 49.2 L of helium gas inside a prep shed. The temperature inside the shed is 11.0 C. The balloon is then taken outside, where the temperature is -31.0 C. Calculate the new volume of the balloon. Assume helium gas is an ideal gas and the pressure on the balloon stays constant. T (in K) = T (in C) + 273.15.
