You pick up a 3.3 kg can of paint from the ground and lift it to a height of 1.4 m.
A. How much work do you do on the can of paint?
B. You hold the can stationary for half a minute, waiting for a friend on a ladder to take it. How much work do you do this time?
C. Your friend decides not to use the paint, so you lower it back to the ground. How much work do you do on the can as you lower it?

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​
