Best Answer

Heat is a form of energy and thus when comes in contact with matter transfers ahead. the molecular structure is made up of several bonds of which some are weak and fragile in double bonds. Heat disturbs this stability by inducing break in weak hydrogen bonds and Vander Val bond and thus disturbs the molecular structure.

when heat and temperature rise it causes the molecules in a substance to gain energy so they will start moving faster.

Heat can cause molecules to spread out and the cold can cause them to become closer together.

When a substace is heated how does the molecular motion change?

The average speed of the random molecular motion increases. The corresponding increase in molecular kinetic energy accounts for what happened to all of that heat energy.

What does Molecular Motion mean?

When the temperature increases during a chemical or physical change the molecular movement increases. This means the molecular movement is faster. If the temperature decreases the molecular movement decreases. This means the molecular movement is slower.


What does heat result from?

Heat is random motion or vibrations that take place on an atomic or molecular level. The faster particles are moving, the hotter they are.
