A pot of water at 20.0ºC is warmed to 100º when 40000cal is added. what is the mass of the water?

500 g

Explanation:

m = Mass of water

c = Specific heat of water =

= Temperature difference =

Q = Heat added = 40000 cal

Heat is given by

The mass of water is 500 g.

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.​
