1. A flask holds 9.73 kg of a monatomic ideal gas (mass number 86.4). If the gas changes temperature isochorically (constant volume) from temperature 802o C to 376o C, find the change in the internal energy of the gas, in kJ. A positive answer means the internal energy increased; a negative answer means the internal energy decreased.  

2. A flask holds 2.25 kg of a diatomic ideal gas (mass number of the gas 92.1). If the gas changes temperature isochorically (constant volume) from temperature 356o C to 519o C, find the change in the internal energy of the gas, in kJ. A positive answer means the internal energy increased; a negative answer means the internal energy decreased.
