A flask holds 8.75 kg of a diaatomic ideal gas (mass number of the gas 82,8). If the gas changes temperature isochorically (constant volume) from temperature 348° C to 752° 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. A flask holds 5.11 kg of a monatomic ideal gas (mass number 283). If the gas changes temperature isobarically (constant pressure)...
