well this isn't a specific question you see there is 2 different kind of substances ;
For example:...
solid : when heat is added to a solid it becomes a liquid
liquid: when heat is added to a liquid it becomes a gas!
for example water > if you add heat it will hot add or take away chemicals!
When Oxygen is added to a substance it is called oxidation.
Overcome intermolecular forces
there is no chemical change when ammonium chloride is added to water. NH4Cl + H2O + heat -> products. it also cold when it is dissolved in water.
When heat is added to water the molecules move faster and faster until the water reaches it's boiling point and starts to vaporize.
The amount of energy it takes to change the temperature of a substance by a certain amount. How much energy it takes to heat a substance ~APEX
When heat is added to a substance, the molecules and atoms vibrate faster.
When a substance is heated it's volume will increase.
If heat is added to it.
Latent Heat.
when acid is added to a substance in the pH, the substance rises in a pressurized state
Heat energy must be added to or subtracted from a substance to cause a phase change.
heat
HEAT
It will change into a gas.Adding heat to or removing heat from a system may result in a temperature change and possibly a change of state. A liquid substance needs heat added to it in order to enter a gaseous state. If enough heat is added to a liquid substance it will change into a gas.
more or less heat
Heat is energy the substance needs to change it's state of matter (the more energy a substance has the higher it's temperature)
