On a day wilderness expedition you'll need to heat of water to the boiling point each day. the air temperature will average . you have available canisters of compressed butane fuel, which you'll burn to heat the water. each canister has of butane in it. what is the minimum number of fuel canisters you must bring? the standard heat of formation of butane at is . you'll probably find other data in the aleks data resource.

Acylinder with a movable piston contains 11.7 moles of a monatomic ideal gas at a pressure of 1.32×10^5 pa. the gas is initially at a temperature of 300 k. an electric heater adds 43200 j of energy into the gas while the piston moves in such a way that the pressure remains constant. cp=20.79 j k^−1 mol^−1 for a monatomic ideal gas, and that the number of gas molecules is equal to avogadro's number (6.022×10^23) times the number of moles of the gas. (a) what is the temperature of the gas after the energy is added? (b) what is the change in volume of the gas? (c) how much work is done by the gas during this process?
