D Question 3 1.75 pts When 2.8 mol of a diatomic gas is heated at a constant pressure of 2.4 atm, its temperature increases from 226.6 K to 311.1 K. Given that the molar hear capacity of the diatomic gas at constant pressure is 29.4 J K-1 mol ], determine AH. Express your answer in Joules to the nearest whole number (XXXX). D Question 4 1.75 pts When 4.1 mol of a diatomic gas is heated at a constant pressure of 1.1 atm, its temperature increases from 230.6 K to 306.1 K. Given that the molar hear capacity of the diatomic gas at constant pressure is 29.4 J K-1 mol , determine AU. Express your answer in Joules to the nearest whole number (XXXX)
