CoachCold resistance refers to a material's ability to withstand low temperatures without damage or degradation. Hot resistance, on the other hand, is a material's ability to withstand high temperatures without damage or structural changes. Both properties are important considerations in choosing materials for various applications.

What is different hot and cold conductor?
A conductor has low electrical resistance when hot and higher electrical resistance when cold. This is due to the increased thermal agitation of electrons in the conductor when it is hot, causing higher resistance compared to when it is cold.
What has more resistance hot air or cold air?
Cold air is more dense, thus is gives more resistance. Notice how you land when you're flying. In the winter, it's usually a smooth gradual landing. In summer, you hit the runway with much more force.
Does a football travel faster in hot or cold?
A football will typically travel faster in hot weather compared to cold weather. This is because the air molecules are more spread out in hot weather, reducing air resistance and allowing the ball to move more quickly through the air.
In which direction does air move: from hot to cold or from cold to hot?
Air moves from hot to cold.
In which direction does heat flow: from hot to cold or from cold to hot?
Heat flows from hot to cold.
