Vaporisation can change the state of matter from a solid or liquid to a gas. During Evaporation the liquid state of matter is turned directly into a gas. ... As for evaporation , only the top level of water is turned into gas. When vapourisation occurs, molecules could come from below the surface when the liquid is boiling.

When matter directly changes from liquid state to gaseous it uses more energy it is called vaporisation but in the case of evaporisation, liquid changes slwly from the surface of the liquid and it requires less energy to chnges its state to gas.

UNIFORM ACCELERATION: Velocity of an object increases or dicreases by equal intervals of time. NON UNIFORM ACCELERATION: Velocity of an object increases or dicreases by unequal amounts in equal intervals of time.

1Thank You

Viraj ... 3 years, 5 months ago

If the velocity of an object changes by an equal amount in equal intervals of time ,then the acceleration of the object is known as uniform acceleration. Ex. Motion of an object falling down. If the velocity of an object changes by unequal amount in equal intervals of time then the acceleration of the object is known as non uniform acceleration. Ex. Motion of a car moving on a crowded road.
