Does anyone know how to do this please

See the answer below.

Explanation:

The latent heat of fusion is defined as the amount of energy needed to make a phase change from solid to liquid. And it can be calculated by means of the following expression:

where:

Qfusion = Heat Energy [J]

m = mass = 0.65 [kg]

Dh =  latent heat fusion = 330000[J/kg]

2)

We know that energy can be calculated from power, where power is defined as the relationship between energy over time.

where:

P = power = 60 [w]

E = energy [J]

t = time = 5 [min] = 300 [s]

The mass change due to the process is equal to:

Now using the following equation for the latent heat of Fusion, we can calculate this value:

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.​
