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.
When gas molecules are heated, their kinetic energy increases, causing them to move faster. This increase in speed leads to higher average velocity and greater collisions with other molecules, resulting in an overall increase in the gas pressure and volume.
it moves faster
Molecules move faster when heated -- no matter what state they're in.
The speed of gas molecules increases as the temperature of a gas increases.
It is true that, in a rigid container, when the speed of the gas molecules increases, the temperature of the gas rises. This has nothing to do with the speed or lack of speed of the gas as a whole.
Yes, when the molecules in a gas are cooled down and their speed decreases, they come closer together and turn into a liquid. This process is known as condensation, and it occurs when the kinetic energy of the gas molecules decreases enough for them to form a liquid.
The molecules absorb more energy, more speed and can be released from the liquid.
That could cause a change from solid to liquid, or from liquid to gas.
When molecules in a body move with increased speed, they gain kinetic energy. If this increase in kinetic energy is significant enough, it can lead to a change in phase, such as from a solid to a liquid, or from a liquid to a gas. These phase changes are a result of the increased movement of molecules overcoming the intermolecular forces holding them together in a particular phase.
The average speed of gas molecules is proportional to the square root of the temperature of the gas. As the temperature increases, the average speed of the molecules also increases. This is described by the Maxwell-Boltzmann distribution of speeds.
As the molecules in a body move with increased speed, i.e. increasing kinetic energy, it is possible that the body will change from the solid phase to the liquid phase, or the liquid phase to the gas phase, and in some cases from the solid directly to the gas phase.
A change in state occurs in both. Also, the molecules, in wich the state contains(solid, liquid,gas), change their movement, and speed.
