90 grams of liquid water are in a cylinder with a piston maintaining 1 atm (101325 pa) of pressure. it is exactly at the boiling point of water, 373.15 k. we then add heat to boil the water, converting it all to vapor. the molecular weight of water is 18 g/mol and the latent heat of vaporization is 2260 j/g.

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
