Thermal Heat and Energy

which states the Law of Conservation of Energy?

• Energy can be created or destroyed along with changing from form to form.

• Energy can't be created, destroyed, or changed from one form into another.

• Energy can't be created nor destroyed, but only change from one form to another.
