How do i figure this out?
explanation not just a answer

Explanation:

Density is mass divided by volume.  For example, Block A:

ρ = m / V

ρ = 60 g / 125 cm³

ρ = 0.48 g/cm³

I assume each block is a cube, so the length of block underwater divided by the side length of the block is the percent underwater.

% = 1.8 / 3.9

% = 46%

Repeat for Blocks B through E.

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.​

explanation:

a fuel engine ( known as a gasoline engine in american english )is an internal combustion engine with spark ignition, designed to run on petrol (gasoline) and similar volatile fuels.
