Any chemical can be hot. Any chemical can be cold.
Dissolving sugar in hot water is a chemical change.
Heating is a chemical phenomenon.
No, it is not.
Yes, the metal bar undergoing a color change due to heating in a fire is a physical change, not a chemical change. Chemical changes involve the formation of new substances with different chemical properties. Heating a metal bar until it glows red hot does not alter its chemical composition.
Its physical because the chemical properities of it doesn't change.

why does chemical weathering happen?
Chemical weathering occurs faster in hot climates because high temperatures accelerate chemical reactions, increasing the rate of breakdown of minerals. In hot climates, there is also typically more moisture which can further speed up the chemical weathering process. Additionally, biological activity is often more prevalent in hot climates, which can also contribute to chemical weathering.
Heating is a chemical phenomenon.
Chemical weathering occurs more rapidly in a hot, wet climate because chemical reactions speed up with increased temperature.

Exothermic chemical reactions release heat.
Only as hot as it is outside. The burns associated with it are chemical, not thermal.
Cooking a hot dog is primarily a chemical change. During the cooking process, the heat causes the proteins and other components in the hot dog to undergo chemical reactions, resulting in changes in flavor, texture, and color. While there may be some physical changes, such as the expansion and browning of the hot dog, the key transformations are chemical in nature.
