Question
The molar heat capacity of a diatomic molecule is 29.1 J·K-1.mol-1. Assuming the atmosphere contains only nitrogen gas and there is no heat loss, calculate the total heat intake (in kilojoules) if the atmosphere warms up by 2.4°C
during the next 50 years. Given that there are 1.8x1020 moles of diatomic molecules present, how many kilograms of ice (at the North and South Poles) will this quantity of heat melt at 0°C? (The molar heat of fusion of ice is
6.01 kJ·mol-1.)
