No.
No. it is not. It is a physical change.
A physical change; more water vapour has joined the cloud, making it thicker and less able to allow light through.
Cloud.
The formation of snowflakes in a cloud is primarily a physical change rather than a chemical change. As water vapor in the atmosphere cools, it undergoes condensation and crystallizes into ice crystals, which then grow into snowflakes. This process involves changes in state (from gas to solid) but does not alter the chemical composition of the water molecules.
a cloud
The temperature inside the cloud is warmer than that around the cloud. Warm air rises, and the cloud stays 'floating'
a meal in Madagascar is like floating on a cloud
That visible mass of water floating in the atmosphere is called a cloud. Clouds are made up of tiny water droplets or ice crystals that have condensed from the air.
Yes, "I wandered lonely as a cloud" is a metaphor. It compares the speaker's experience of solitude to that of a cloud floating aimlessly in the sky.
Original answer is INCORRECT. Clouds forming in the sky is a physical change because a chemical change requires a change in the chemical composition of a material and the H2O, no matter a solid liquid or gas, is always H20.
Yes the word cloud is a noun. It can also be used as a verb.
A nebula is a physical change. It is a cloud of gas and dust in space that is not undergoing any chemical reactions. The process of a nebula forming into a star involves physical changes such as gravity causing the gas to condense and heat up.
