1 The particles of an ideal gas lose no energy to its container. 2  A real gas conducts and radiates heat, thereby losing energy. 3  There is no attraction between the molecules of an ideal gas. 4  A real gas has particle attractions.
â¢ Another difference between the two gases pertains to their weight. Propane is heavier than natural gas and in case of any leakage, it falls down on the ground and thus poses a greater risk of injury than natural gas which is lighter and dissipates into air. â¢ Propane is more energy efficient than natural gas.For the same amount of gas, propane gives 2550 BTU whereas natural gas gives only 1000 BTU. But this better thermal efficiency does not translate into any profit as propane is costlier than natural gas. Propane is more energy efficient than natural gas.
