MOST matter expands as it gets hotter.

Temperature!! Heat causes the medium (matter of sort) to expand, and cold causes it to contract. Hence why you need cold temperature for gases to become liquids.


Yes glass does expand a little with heat but it contacts more when cold and can crack if not carefully watched.


It is heat that makes stuff expand. We call the change thermal expansion in physics.


when the molecules get heated up, they move around more, making the matter expand


Rubber expands with the cold and contracts with heat


All matter expands somewhat due to heat. So yes, headlights will expand slightly when hot versus cold.


Heat causes matter to become warmer, usually to expand,and occasionally to change its physical state.


Matter is matter, and heat is not cold. But matter is cold, and heat is not warm but yet very hot. I understand the living conditions in Europe. Yes, I am very correct and also wiser than u.. :)


it is related to states of matter because when you add heat to the particles the space between the particles expand.


Yes. Yes. Yes. Yes. It makes brass expand. Guess what cold does!



Because molecules in matter are always moving, virtually all matter has some heat energy, even when it seems cold to you. Matter that seems cold is merely not as hot as objects near it, or as hot as your hand. It still has temperature and thus heat energy. As long as its temperature is above -459.7°, it has heat energy.


Muscles expand and contract as a way to produce heat for the body.


fire/heat makes matter expand the melt away


Yes, the heat causes the air to expand in the tires. Conversely, the cold air in winter reduces tire pressure.


Heat energy causes all matter to expand, a reason for this strange occurrence is that when a particular substance receives heat whether it be through conduction, convection or radiation the atoms inside the substance become more energised therefor needing more space to move, they push the outside boundaries making the substance expand. If the substance receives an exceeding amount of heat energy it will change states of matter.

Heat(Hot) makes a object expand or get bigger. Cold makes a object shrink or get smaller.


The application of heat energy usually causes matter to expand, not contract.There one or two exceptions, eg. water (as ice) contracts as you melt the ice.


All balloons expand in heat.


A concrete patio usually cracks due to heat cold. If it is to cold it contract and break. If it is to hot it will expand and break. Then water can seep into those cracks and freeze causing the crack to expand


Most substances will expand when heated. -- So the volume becmes greater.


This is because when heat is applied to particles, they gain energy, therefore they travel faster and space out. The volume will increase though the density will decrease. So matter will always expand when exposed to heat.


i believe heat does expand... I'm not sure though. i think the particles separate to have room to vibrate. that causes the heat to expand. :)


yes, the heat makes the particles move and in the heat they expand.
