In a cylinder with methane with a capacity of 60 liters at 0°C there was a pressure P = 80 atm. The cylinder was connected to a gas burner with an efficiency of 80% and, burning methane, the water was heated. If you then heat the balloon to 80°C, pressure P will be established in it again. How much water could be heated from 0°C to boiling? Calorific value of methane q = 41.8 kJ/g, molecular weight 16.
