What happens to the particles of matter when thermal energy is added to it?
When thermal energy is added to particles of matter, it causes the particles to move faster and emit more energy.
Why does adding heat cause particles to vibrate faster?
Heat is a form of energy, you are adding energy to the system, this causes the particles to vibrate faster.
Why do material particles vibrate?
Thermal energy in a material causes the particles to vibrate. Particles cannot stop moving altogether, since they would then violate the Heisenberg uncertainty principle. This states that we cannot know a particles speed and position to infinite precision at the same time. A particle in a material that is not jiggling would violate this. The more and faster that the particles are jiggling, the more energy they must have. If they come into contact with particles that are jiggling less, then that energy spreads. The faster jiggling particles slow down, transferring their energy to the slower particles, which speed up. This is just the transfer of heat from one material to another! Here's a good video from famous physicist Richard Feynman explaining "jiggling atoms."
How Does Thermal Energy Cause Change?
An increase in thermal energy gives particles more kinetic energy, which causes them to vibrate more. As they vibrate more, the volume they take up increases.
Why do materials expand once heated?
This is called thermal expansion. When an object is heated, it's particles move faster. This causes greater separation between the particles and the object expands. The coefficient of thermal expansion describes how much an object will expand per degree with the same applied pressure.
What causes the particles of a substance to lose thermal energy?
The particles in a substance lose thermal energy as the temperature decreases, because the particles are moving and vibrating less.
What happens to the particles of matter when thermal energy is added to it?
When thermal energy is added to particles of matter, it causes the particles to move faster and emit more energy.
Why does adding heat cause particles to vibrate faster?
Heat is a form of energy, you are adding energy to the system, this causes the particles to vibrate faster.
What causes thermal conductivity?
when heat travells through a material which over heats it. Thermal conduction then applies
What is it called when the particles of an object start to move faster and causes it to grow?
Thermal expansion

Causes particles to vibrate in place?
the thermal energy is what causes the particles to vibrate.

What happens to an ideal gas in a closed container when temperature rises?
In a container of constant volume, when the gas is heated, thermal energy is converted to kinetic energy. This increase in kinetic energy causes the gas particles to accelerate. This acceleration of particles causes the particles to crash into each other, increasing pressure. Because it is a closed container, the number of particles and the volume the particles take up remain the same.
What can casuse a thermal burn?
heat causes a thermal burn
Which energy transformation takes place in a match head when light the match?
The mechanical energy used to strike a match is transformed first to thermal energy. The thermal energy causes the particles in the match to release stored chemical energy, which is transformed to thermal energy and the electromagnetic energy you see as light.
