A water tank is filled with water up to 3.5m in height. calculate the pressure given by the tank at its bottom.

Explanation:

We are told that the height of the water tank is 3.5 m.

Now, the formula for pressure is;

P = ρgh

Where;

ρ is density of water = 1000 kg/m³

g is acceleration due to gravity = 9.8 m/s²

h = 3.5 m

Thus;

P = 1000 × 9.8 × 3.5

P = 34300 N/m²

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.​
