What is convection heating from a campfire?
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.
What is the energy produced by random movements of molecules called?
The constant random motion of molecules caused by their inherent kinetic energy is called Brownian motion . It describes how particles in solution and even individual molecules randomly move as energy moves through a system.
How does heat make molecules move?
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.
What are 3 ways heat is produced?
Conduction, convection and radiation TRANSFER heat; you can't create heat; the law of conservation of energy states that energy cannot be created or destroyed. Therefore, you can't create heat.
What makes solids melt?
When we heat a solid, the energy is transferred to the molecules, and to the bonds between the molecules. Eventually, the bonds become broken and the molecules become free to move about. Just as in a liquid.
Do molecules in water move slower in cold water?
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.
Why do molecules move slower when you remove the heat?
because they do Molecules move firstly due to their own kinetic energy. On addition of heat energy is now present in the environment for the molecules to use,so they use it.This energy is used as kinetic energy and the molecules can therefore move faster than they normally would. Once you remove the source of the extra energy from the system the molecules go back to moving in their natural momentum.
When energy is removed from a liquid do the molecules move faster or slower?
I might be wrong, but I would say slower. If you mean energy in form of heat, molecules move slower if the liquid is colder, so if a liquid releases energy in form of heat (turns ¨cooler¨), than the molecules move slower. As I said, I might be wrong. Just my thoughts
What makes molecules move faster?
The input of energy into the system. Most of the time, that energy is heat.

How does heat energy affect the movement of particles?
If you take a vessel full of water and heat it with the spirit lamp you will find that when the heat energy is continuously transferred the molecules in the vessel gets the energy as a result they move in a faster rate. The transfer of heat energy to any molecules increases its kinetic energy.
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.
What kind of energy causes molecules to move around quickly?
Kinetic Energy. Kind of like heat.
How are heat and Thermal energy related?
it is related because heat is temperature and temperature tells how fast molecules move and thermal energy is kinetic + potential energy
What happens when molecules are heated and why?
They move faster because the heat gives them more energy
What happens to all matter when heat?
the atoms use the energy to move the molecules
