Answer 1

Answer:

9. Muscles use the stored chemical energy of food we eat and convert that to heat and energy of motion (kinetic energy).

2. Here are only some of your many choices for heating energy sources: natural gas, propane (LP), oil, coal, wood, electricity, heat pumps, ground source heat pumps and solar energy. Radiantec strives to offer products that are highly energy efficient and yet still a smart investment.
