What is the process by which a gas changes to a solid?
Deposition is the phase transition in which gas transforms into solid without passing through the liquid phase. The reverse of deposition is sublimation and hence sometimes deposition is called desublimation.
When a liquid is changing to a gas Which of the following is correct?
At a certain temperature, the particles in a liquid have enough energy to become a gas. The process of a liquid becoming a gas is called boiling (or vapourization), while the process of a gas becoming a liquid is called condensation.
Which is the process by which a solid changes to a?
Sublimation is the process of transformation directly from the solid phase to the gaseous phase, without passing through an intermediate liquid phase. At temperatures and pressures below those of the triple point, a phase change between the solid and gas phases can take place.
Are freezing and melting reverse process?
Freezing is the process of changing a liquid into a solid by cooling whereas melting is the process of changing a solid into a liquid by heating. Hence it can be said that freezing is the reverse of melting.
Which is the reverse process of freezing?
Freezing is the process of turning a liquid into solid by cooling. But Melting turns solid into liquid by heating. Thus melting is the reverse process of freezing.
What happens to matter at melting point?
The atoms in a liquid have more energy than the atoms in a solid. There is a special temperature for every substance called the melting point. When a solid reaches the temperature of its melting point, it can become a liquid. Liquid water freezes and becomes solid ice when the molecules lose energy.
Is melting point and boiling point the same?
The boiling point is the temperature at which a material changes from a liquid to a gas (boils) while the melting point is the temperature at which a material changes from a solid to a liquid (melts). Keep in mind that a material’s melting point is the same as its freezing point.
