An ideal monatomic gas is contained in a vessel of constant
volume 0.330 m3. The initial temperature and pressure of the gas
are 300 K and 5.00 atm, respectively. The goal of this problem is
to find the temperature and pressure of the gas after 24.0 kJ of
thermal energy is supplied to the gas.
(a) Use the ideal gas law and initial conditions to calculate
the number of moles of gas in the vessel. Your response differs
from the...

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...
