Grilling a steak increases the thermal energy by transferring heat from the grill to the steak. This results in the meat cooking and increasing in temperature.
Steak is a form of potential energy because it contains stored energy in the form of chemical bonds that can be released and converted into kinetic energy when it is consumed and metabolized by the body.
