Can chemical energy be converted to gravitational potential energy?

Answer 1

By using chemicals in a rocket engine to raise a vehicle high above the earth's surface, the vehicle will gain gravitational potential energy. It will also gain kinetic energy, depending on what trajectory it follows

Answer 2

Yes, chemical energy can be converted to gravitational potential energy. This can occur, for example, when an object powered by a chemical reaction moves against the force of gravity, causing a transfer of energy from the chemical bonds to the object's position in a gravitational field.
