it moves faster
The average speed of its molecules increases with heating and decreases with cooling. You may also find it interesting that the faster the molecules are moving the more they will hit the walls of the container and thus the pressure in the container will also go up with heating and down with cooling.
The speed of the movement of the molucules is increased as they absorb heat energy. This is why solids 'melt' to liquids and then 'vapourise' to gas - the molecules are moving faster and further apart.
More heat = more energy. If the gas molecules have more energy, they express it in the form of kenetic energy (the energy of motion). therefore, more heat = more speed.
If there is a lack of energy, the particles slow down. If enough energy is taken away, it will change physical states to liquid, then to solid. Ie. Gaseous nitrogen is chilled to below -70 degrees C and becomes liquid nitrogen as the speed of the molecules slows down.
The speed of the gas particles will increase as they are heated. That is why the pressure in a container increases. The particles are hitting the walls of the container with more force as they are heated.
At higher temperature (heating up) all particles move faster.
it moves faster
Increases
Decreases
The speed of the molecules speeds up when the gas is heated.
they get heated up and evaporate
Gas molecules change their motion when they bounce into the surfaces of their containers. If the surfaces absorb the impact, then energy is transfered out of the system and particle speed decreases.
Liquid to a gas
The molecules of a gas move faster when heated so the pressure increases.
The speed of the molecules speeds up when the gas is heated.
it moves faster
Molecules move faster when heated -- no matter what state they're in.
When a gas is heated it's molecules begin to move faster and farther apart, juat as all other states of matter will when heated.
The molecules absorb more energy, more speed and can be released from the liquid.
they get heated up and evaporate
When gas is heated then its molecule get energy and start to move faster.
The kinetic energy content increases and the speed of its particles increases.
When matter is heated the molecules move faster and the speed becomes so great the molecules cannot hold together. The molecules fly apart and become a gas.
Gas molecules change their motion when they bounce into the surfaces of their containers. If the surfaces absorb the impact, then energy is transfered out of the system and particle speed decreases.
Liquid to a gas
The molecules of a gas move faster when heated so the pressure increases.
