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.
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.
Atoms comprising a molecule move faster as heat increases.
So when molecules are heated, the heat is so intense that they have to move around for them to cool down.
When it is cold, molecules move slower than when it is hot.
The simplest answer is: the fire adds heat energy to the air molecules near it. The higher energy molecules start bouncing around faster. When these molecules move away from the fire, they carry the energy (heat) with them.
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 molecules move slower when heat is removed.
heat
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
No, as heat is lost molecules move slower.
adding heat to a substance makes its molecules to move quickly
Yes, the less heat there is present, the less heat, the slower the molecules will move. This is due to a lack of energy given from the heat.
Heat is the speed of which molecules move in an object.
