Changing temperature, density and pressure occur when a chemical reaction.
Heat?
No, chemical changes can occur at various temperatures depending on the specific reaction. While many chemical reactions do happen at higher temperatures to provide enough energy for the reaction to occur, there are also reactions that occur at lower temperatures. Temperature is just one factor that can influence the rate of a chemical reaction.
a precipitate is a solid that forms during a chemical reactions
When an antacid tablet dissolves in water, it is a chemical reaction. The tablet reacts with the water to neutralize excess stomach acid, which changes the chemical composition of both the tablet and the water.
Changes in energy themselves are not considered chemical changes. Instead, changes in energy may occur as a result of a chemical change taking place, such as in an exothermic or endothermic reaction where energy is either released or absorbed.
Chemical changes occur after a chemical reaction.

A chemical reaction, a chemical change.

It depends on the chemical reaction. For example when you burn something it is a chemical reaction, but that is way different than if you mix baking soda and vinegar which is also a chemical reaction. It changes the matter into a different chemical matter make up of that substance.
An exothermic reaction and the change between potential and kinetic.

A reaction in a chemical reaction refers to the transformation of one or more substances into new substances with different properties. This process involves the breaking and formation of chemical bonds between atoms or molecules. Energy changes may also occur during a chemical reaction.

A chemical change. Color change is a good indicator of a chemical change.
