What is the substance that absorbs and releases heat in a cooling system?
A refrigerant is a substance that absorbs and releases heat in cooling systems.
Does a solid dissolve faster when you stir the solution?
Yes. This is due to the movement of the molecules. As you stir the solution, there is more kinetic energy. The more kinetic energy something has, the more heat is produced, which causes a substance to dissolve faster. In addition, stirring causes the substance to be exposed to more surface area.
Why does heating a substance causes molecules to expand?
There is the Kinetic theory of matter. All matter is made up of atoms and molecules that are constantly moving.When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.Mass of the object remains the same, however. Solids, liquids and gases all expand when heat is added. When heat leaves all substances, the molecules vibrate slower. The atoms can get closer which results in the matter contracting. Again, the mass is not changed.Best regards, Aleh Aprelenka
How do the molecules act in a soild?
the molecules are in fixed positions but are slightly vibrating :), and when energy is applied (heat) the molecules star vibrating faster
What does heating increase the speed at which a solute dissolves in water?
It will affect it because the chemicals in what you are trying to dissolve, will increase if you put it in hot water. The chemicals dissolve much faster the higher the temperature.
What happens to the molecules of a substance when it is melted?
the molecules vibrate, faster and faster as the heat increases then they become disordered
What happens to atoms of A substance when heat is added?
When heat is added to a substance, the molecules and atoms vibrate faster.
What is it when something absorbs heat?
What happens is that the molecules will move faster causing the object's temperature to increase and expand.
What is the substance that absorbs and releases heat in a cooling system?
A refrigerant is a substance that absorbs and releases heat in cooling systems.
Why do you get heat?
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.
If heat is removed from a substance how will atoms behave?
Kinetic theory of matter: All matter is made up of atoms and molecules that are constantly moving. When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. ... They contract when they lose their heat.
When a substance melts or boil it absorbs what?
Heat.
When a substance melt or boils it absorbs?
Heat
When does land and water absorb and lose heat?
It absorbs heat faster
When an ice cube is dropped in water which substance water or ice absorbs heat?
The ice absorbs heat from the water, which is why it melts
What is the driving potential for heat transfer?
The driving potential for heat transfer is the temperature difference between two systems. Heat will naturally flow from a higher temperature to a lower temperature in order to reach thermal equilibrium.
How do electrons help in transfer of heat energy?
when a substance is heated,the molecules in that substance get heat energy. we know that all of the molecule in the substance having electrons. when substance is heated. electrons becoming high energetic.and they move faster and also energy will propagate though out the substance
