MOST matter expands as it gets hotter.
Objects contract or expand depending on the temperature. Cold makes things contract, heat makes things expand. However, there are some exceptions. For example, water expands when it turns to ice. This is due to the process of crystallization. The reason that objects expand and contract is found at the atomic level. When an object is warm, its molecules move faster and spread out, making that object expand. However, when an object is cold, the atoms slow down and move back together, making the object contract.
Space is cold because it is a vacuum, meaning there is no matter to trap heat. Without any particles to transfer heat, objects in space lose heat quickly, making it very cold.

Yes all matter does have some heat energy in it
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.
Cold causes matter to contract. Heat causes matter to expand.
All matter expands somewhat due to heat. So yes, headlights will expand slightly when hot versus cold.
Heat causes expansion.
Heat causes matter to become warmer, usually to expand,and occasionally to change its physical state.
Cold is not a matter, but rather a description of the absence of heat energy. Cold is perceived when objects or substances have a lower temperature than our bodies, causing heat to flow from our bodies to the colder object, making us feel cold.
They expand in heat to allow blood to reach the extremities to be cooled.. Exactly the opposite is true when there cold.. Blood is drawn away from the extremities to help keep vital organs warmer.
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.
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.
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
Heat can increase the temperature of matter, causing it to expand or change state from solid to liquid or liquid to gas. Additionally, heat can break chemical bonds within matter, causing it to undergo chemical reactions or decompose.
