a) The molar heat capacity of a diatomic molecule is 29.1J/K·mol. Assuming the atmosphere contains only nitrogen gasand there is no heat loss, calculate the total heat intake if theat mosphere warms up by 5°C during the next 50 years.
b) Given that there are 2.7 
1020 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?
