Twenty Grams Of Oxygen Gas Undergo Changes From T 24 C And V 28 L To T 45 C And V2 46 L In The Process Work 1 (19.06 KiB) Viewed 30 times

Twenty grams of oxygen gas undergo changes from T₁ = 24°C and V₁ -28 L to T₂ = 45°C and V2 = 46 L. In the process, work equivalent to 2100 kJ is done by the system. Assuming that the gas is ideal, calculate the following: a.) change in internal energy in kJ b.) heat absorbed or released in kJ c.) change in enthalpy in kJ d.) change in entropy in kJ/K Note: The heat capacity of oxygen is a function of temperature. Use Cp/R table and R = 8.314
