Why charcoal have high value of heat combustion than petrol?
Petrol has a higher value of the heat of combustion.
Do Mylar balloons expand in heat?
All balloons expand in heat.
Does heat make gas contract or expand?
Heat makes gas expand. When gas is heated, its molecules gain energy and move faster, increasing the pressure and causing the gas to expand in volume.
What energy is released when petrol burns?
When petrol burns, chemical energy stored in the molecules of petrol is converted into heat and light energy. This is a result of the combustion process, where the carbon and hydrogen in petrol react with oxygen to form carbon dioxide and water, releasing energy in the form of heat and light.
Does aluminium swell?
No, although it does expand with heat as do most substances.
Why charcoal have high value of heat combustion than petrol?
Petrol has a higher value of the heat of combustion.
Do Mylar balloons expand in heat?
All balloons expand in heat.
Can you explain why a sealed can partly filled with petrol may begin to bulge in hot weather?
The sealed can will bulge in hot weather because the heat causes the petrol to evaporate creating more gas fumes in the can. This heat energy absorbed by the can converts to a change in energy of the petrol, Delta E=P Delta V. The outside atmosphere pressure P, being a constant, causes the volume V to expand. This explains why, if the petrol can is made of thin material, it bulges.
Does a solid expand?
yes, the heat makes the particles move and in the heat they expand.
Why does a petrol pump have a volume measurer inside it?
A petrol or gas pump has a volume measurement device inside it to measure the expansion of the gases that come from the petrol. As the gases expand, they can actually cause explosions.
If you heat an object it will?
expand
Why do oven trays expand and contract?
heat makes metal expand.
You feel cold when a drop of petrol falls on your skin?
Petrol evaporates quickly and absorbs heat from the surroundings, including your skin. This rapid heat transfer can make you feel cold when a drop of petrol falls on your skin. Additionally, the cooling effect can be enhanced if the petrol is at a lower temperature than your skin.
What happens to a petrol tank in hot weather?
Nothing happens to the tank but the fuel will expand slightly.
Is burning petrol a chemical reation?
Yes. burning petrol chemically creates a whole new set of chemicals. depending on the heat and exact composition of the petrol.
How easy is petrol to store?
Petrol is just gasoline, and is very easy to store. Petrol can be stored in a thick plastic container, kept out of sunlight and away from heat.
What happen when materials are heat?
They expand.
