An iron block with the respective measures 10 cm x 20 cm x 50 cm at an initial temperature of 25°C. After being heated to a temperature of 50°C what will be the final volume of the iron block?

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.

mass:

given values:

mass = 0.3 kg.

the answer is 100. i just did this lesson and got a 100% on it. : )
