What else can I help you with?
When heat is added to water what occurs?
makes the molecules in the water move faster.
What type of energy makes molecules move faster and can cause phase changes?
Thermal
How is electricity used to make the heater working?
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.
Why does heating increase the speed at a solute dissolves in water?
It makes the water molecules move faster.
When energy is converted to molecules and they move faster does temperature increase or decrease?
As molecules move faster, they cause friction, which increases the temperature of the molecules.
Which occurs when air is compressed A. Air Temp rises and air molecules move faster B. Air temp decreases C. Air temp decreases and air molecules move faster D. Air molecules move slower?
A. air temperature rises and air molecules move faster
What changes takes place during evaporation and condensation?
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.
Will an aluminum door expand in the summer or winter?
It will expand in Summer as the heat makes the aluminum molecules move faster causing them to expand
Do molicules move faster in a solid or in a liquid?
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.
Does alcohol make molecules move?
Heat makes molecules move. Alcohol, if used as a solvent, makes some molecules more mobile.
Do molecules move faster when heat increases?
Atoms comprising a molecule move faster as heat increases.
Do molecules move slower or faster or the same during evaporation?
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.
