water vapor
Water becomes dense when it is more saturated than absorbing a solution. For example, salt with make water more dense because as more salt is added, it becomes saturated.
it expands and it becomes bigger
due to heat, air expands and density decreases.air becomes lighter.lighter air rises up .
When air becomes warm, it expands and becomes less dense, causing it to rise. This can lead to the formation of clouds and eventually precipitation. In water, warmth can increase its evaporation rate and decrease its density, causing it to rise as well.
decreases as it becomes less dense and expands. This is why warm water rises in cooler water.
Water becomes dense when it is more saturated than absorbing a solution. For example, salt with make water more dense because as more salt is added, it becomes saturated.
Water expands when it freezes and becomes ice.
Water vapor in the atmosphere condenses when it cools to its dew point, the temperature at which air becomes saturated with moisture. This cooling can occur due to rising air, which expands and cools, or contact with cooler surfaces. As the air cools, it can no longer hold all the moisture as vapor, leading to the formation of tiny water droplets or ice crystals, resulting in clouds, fog, or precipitation.
After clouds form as warm air rises, expands, cools, and becomes saturated, the water vapor condenses into tiny water droplets or ice crystals, depending on the temperature. These droplets cluster together, creating visible clouds. When the droplets coalesce and grow larger, they can eventually fall as precipitation, such as rain or snow, depending on the atmospheric conditions. This process plays a crucial role in the Earth's water cycle and weather patterns.

condensationCondensation creates clouds. Clouds develop in an air mass that becomes saturated (relative humidity becomes 100%).Read more http://www.kgbanswers.com/in-what-process-must-occur-for-clouds-to-form/4008725#ixzz1EQ3cx57a
No, when matter becomes heated it always expands, meanwhile when matter becomes cool it always contracts.
it expands and it becomes bigger
It expands, rises, and becomes less dense.
When air is heated, it expands and becomes less dense. This causes its molecules to move more quickly, increasing the air's temperature.
This is becuase it becomes a solid and the particles expand to fit neatly into a solid square.
The individual air molecules' kinetic energy increases, thus, increasing the amount of collisions between the molecules. It expands, so it becomes less dense than the surrounding air and therefore it rises (floats) upwards.
