The gas it uses.
air
when u pass gas
A hot air balloon uses heated air to generate lift, while a gas balloon uses a lighter-than-air gas, such as helium or hydrogen. Hot air balloons are propelled by wind currents, while gas balloons can be steered to some extent using ballast and vents. However, gas balloons typically have longer flight durations compared to hot air balloons.
An Air Rifle is either a BB rifle or a pellet rifle. It uses air or gas to propel the projectile.
Uses the gas from the burning propellant
A gas clothes dryer uses a gas burner to heat the air inside the dryer. The heated air is then circulated through the clothes drum to remove moisture from the clothes. The moisture-laden air is then vented outside, while the cycle continues until the clothes are dry.
You can only get gas heating and air conditioning. The gas heating and air conditioning is less because it uses less gas then how much water you would be using. The electricity for the heater and AC can be fairly cheep.
no, it just uses your car battery
hot plate
Convection is the form of heat transfer that uses liquid and gas for heating. It involves the movement of fluids, such as liquid or gas, to transfer heat from one part of a fluid to another. This can occur naturally, such as when hot air rises, or can be artificially induced, such as in forced-air heating systems.
No. A car heater gets its heat from the motor and uses no extra gas at all, unlike a car's air conditioner which does use more gas.
