Acylinder contains oxygen at a pressure of 2.00 atm. the volume is 4.00 l, and the temperature is 300 k. assume that the oxygen may be treated as an ideal gas. the oxygen is carried through the following processes: (i) heated at constant pressure from the initial state (state 1) to state 2, which has t=450k. (ii) cooled at constant volume to 250 k (state 3). (iii) compressed at constant temperature to a volume of 4.00 l (state 4). (iv) heated at constant volume to 300 k, which takes the system back to state 1.

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.
