What three phase changes need the input of thermal energy?
The three phase changes that require the input of thermal energy are melting, vaporization, and sublimation. Melting is the change from solid to liquid, vaporization is the change from liquid to gas, and sublimation is the change from solid to gas. In all these processes, thermal energy is needed to break the intermolecular forces holding the particles together.
What is the change in condesation?
Condensation is when water vapour (steam) turns into a liquid. When water vapour are gas particles which have a lot of energy and go in all directions however when water vapor is cooled the particles lose energy and when they bump into each other they do not have enough energy to bounce again so they stay together and form a liquid
How does the temperature of a liquid change when it boils?
vapour
The Change from a liquid to vapor is called?
The change of liquid the vapour state is known as EVAPORATION.It is a physical change ,because no ne substance is formed.It is only a change of state and the liquid can be recovered by Condensation of the vapour.
When does liquid change to vapor?
it depends what the liquid is. water liquid turns into vapour at 100c
Is evaporation a change between which two states of matter?
Evaporation is a change from a liquid state to a gaseous state. It occurs when molecules in a liquid gain enough energy to escape into the air as vapor.
Is rain evaporation physical or chemical?
Physical change from liquid to vapour. The water remains chemically the same whether liquid or vapour.
When energy is added to a liquid and it changes into a gas it is called?
When energy is added to a liquid causing it to change into a gas, it is called vaporization or evaporation. This process involves the liquid molecules gaining enough energy to break free from the attractions holding them together in the liquid phase and transition into the gaseous phase.
What is wet vapor?
Wet Vapour is the region which contains a mixture of liquid and vapour. The liquid is saturated liquid and the vapour is saturated vapour. The temperature stays uniform until the entire phase change is complete.
Is evaporation a chemical change?
No, evaporation is a change from liquid to gas (water vapour).
What is needed to change a vapour back to liquid?
To change a vapor back to a liquid, you need to decrease the temperature of the vapor below its boiling point so that it condenses. This can be achieved by cooling the vapor in a process known as condensation.
What is change in the physical state of both lavender oil vapour and water vapour as they cool?
they turn from gas to liquid
