Task id12862
In a cylinder with methane with a capacity of 50 liters at a temperature t0 = -23°C there was a pressure Po = 150 atm. The cylinder was connected to a gas burner and, burning methane, melted 10 kg of ice with the same initial temperature, turning it into water with a temperature of 0 ° C; burner efficiency 80%. At what temperature must the cylinder be heated in order for the pressure Po to be established in it again? The calorific value of methane is q = 41.8 kfu/g. Specific heat capacity of ice 2.1 J/g • deg.
