Water vapour loses heat because it condenses back to liquid form. When its cooling, the liquid state changes to solid state and form a ice.
The temperature at which the water in liquid form vapourises is called boiling point and that where the solid turns to liquid is the melting point.
There is a corresponding decrease in the volume of the gas.
Another perspective:
To a certain point, it will condense to liquid. In micro scale, thermal energy is Sum of gas particles kinetic energy. Loosing energy and the attract force will pull the molecules close together.
When gases lose heat they condensate into liquids.
It gts cold. If it gets cold enough, it condenses, and becomes a liquid.
they move like old people
A loss of kinetic energy in the atoms or molecules of a sample of matter will result in the cooling of the sample. That sample will get colder as remove thermal energy from it. The atoms/molecules of a substance have kinetic energy associated with them. This kinetic energy is the result of atomic and/or molecular motion. As a sample of matter cools, the atoms and/or molecules will lose mobility. Loss of mobility and vibrational energy, which are forms of kinetic energy, will become apparent when thermal energy is removed from the sample.
The particles will move slower as energy is lost.
its particles stop moving around because of loosing kinetic energy. As you know kinetic energy is something that moves around .And particles in sample of matter cool off and stop.
Heat (thermal energy)
The particles in a substance lose thermal energy as the temperature decreases, because the particles are moving and vibrating less.
the particles in a gas lose enough thermal energy to form a liquid.
condensation
yes
yes
they move like old people
they dont move as much
its loses thermal energy...

It changes shape.
The particles will move slower as energy is lost.
