The input of energy into the system. Most of the time, that energy is heat.
makes the molecules in the water move faster.
Thermal
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.
It makes the water molecules move faster.
As molecules move faster, they cause friction, which increases the temperature of the molecules.
A. air temperature rises and air molecules move faster
Evaporation - the fastest molecules escape 1. When a Liquid is heated, the heat energy goes to the molecules, which makes them move faster. 2. Some molecules move faster than others. 2. Fast-moving molecules at the surface will overcome the forces of attraction from the other molecules and escape. This is Evaporation.
It will expand in Summer as the heat makes the aluminum molecules move faster causing them to expand
Molecules in a liquid move faster than in a solid because the intermolecular forces in a liquid are weaker, allowing molecules to move around more freely. In a solid, molecules are held tightly in a fixed position by strong intermolecular forces.
Heat makes molecules move. Alcohol, if used as a solvent, makes some molecules more mobile.
Atoms comprising a molecule move faster as heat increases.
Molecules move faster during evaporation because when a liquid evaporates, the molecules gain energy from the surroundings, increasing their kinetic energy and causing them to move more rapidly.
