n ideal monatomic gas is contained in a vessel of constant volume 0.400 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 18.0 kJ of thermal energy is supplied to the gas. Using the ideal gas law and initial conditions to calculate the number of moles of gas in the vessel =80.99 moles. Find the specific heat of the gas. In J/K What is the work done by the gas during this process? In kJ Use the first law of thermodynamics to find the change in internal energy of the gas. In kJ
