a cylinder with a radius of 40cm and a depth of 50cm is filled with air at a temperature of 20°c and a pressure of 1.0atm, as shown in figure (a). the piston has a final mass. until equilibrium at height h as in figure (b). 25.0kg stood on the piston to blow air with a temperature of 20.0°c as shown (c). a. how much does the piston move down when the dog is standing on it? b. what is the air temperature equal to the piston and the dog up to height hi?

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.​
