True or False: As water evaporates, it removes a lot of heat with it.

True, when it evaporates heat goes down, because it’s up the the sky.

Facts: In order for water to evaporate, hydrogen bonds must be broken. Water's heat of vaporization is 540 cal/g.

Because of the need for so much energy to evaporate, as water leaves the surface from which it is evaporating and removes a lot of heat with it.

no. dot product   =0 when vecs at right angles

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is
