A hot air balloon uses a gas flame to heat the air it contains to a temperature required to enable it to hover at a small distance above ground level. The mass of the balloon, ropes, basket and riders is 240 kg and the volume of the balloon is 1100 m³. The temperature of the surrounding air is 15°C and its density is 1.23 kg m-³. To what temperature does the air in the balloon need to be heated? [5]
