Heat gives energy to the molecules or the atoms.hence the energized atoms or molecules start vibrating and their power of bonding with other atoms or molicules become weak.
The number of collisions with enough energy to react increases.
Acetone molecules evaporate when you add heat to a beaker of liquid acetone.
Smaller molecules called amino acids make protein molecules.
the molecules are in fixed positions but are slightly vibrating :), and when energy is applied (heat) the molecules star vibrating faster

The heat energizes the molecules.The molecules of air will move here and there as they are free. Molecules of solids vibrate at there place.Due to heat the molecules get energized that is the main thing.
Heat makes molecules move. Alcohol, if used as a solvent, makes some molecules more mobile.
Energy makes molecules rapidly move faster and faster, and when you make molecules move faster you are creating heat. So by using electricity(energy), you speed up the molecules of water, thus creating heat.
The energy not used to make ATP molecules generates heat.
Heat is added to ice to make it melt.
The molecules that compose or make up a solid, such as land, need more energy or in this case heat, to move them. The molecules are compact where as in liquid they have more mobility. When a substance heats, its molecules move faster. Since liquid's molecules have more mobility, liquid heats more quickly.
the water molecules move away, e.g. evaporate
The molecules move slower when heat is removed.
Yes, because the gas molecules in the tennis ball expand. When the molecules expand there energy increases.
Quite simply, heat occurs because the molecules in an object or substance move very quickly. All matter, or substances, contain molecules which are always in a state of motion, and actions such as movement can make the molecules move faster, creating heat. Heat transfers because it is energy which travels in waves, and when it touches something else, the molecules in the new item or substance also become excited, moving faster and faster to create heat.
Water molecules retain energy due to heat transfer.
