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.
Answer:
(☞ ಠ_ಠ)☞ Work, in physics, measure of energy transfer that occurs when an object is moved over a distance by an external force at least part of which is applied in the direction of the displacement.
If the force is being exerted at an angle θ to the displacement, the work done is W = fd cos θ.
(☞ ಠ_ಠ)☞S.I. unit of work is Joule.
(☞ ಠ_ಠ)☞ if the force has a component in the same direction as the displacement of the object, the force is doing positive work. it is positive work done. =780 J. She has done work against the gravitational force of earth.
