Ice must absorb heat to melt into water. what must water do to evaporate?

The temperature must be increased in order to evaporate water

Evaporation happens when atoms or molecules escape from the liquid and turn into a vapor. If the energy of water molecules is increased which means heat is released then the water molecules come to surface of the container and leaves it. These water molecules are called vapors. When water is heated, the molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor.

Explanation:

From the ideal gas equation

PV=nRT

P=Pressure

V=Volume

R=Ideal gas constant

T=Temperature

n=number of mole

P=745mmHg

760mmHg=1atm

745mmHg=0.98atm

volume of water displaced=volume of hydrogen produced=145ml=0.145L

R=0.082Latm/mol/K

T=22°C=273+22=293K

no of mole=PV/RT

=0.98×0.145/0.082×293

=0.1421/24.026

=0.0059mol
