Anything that produces thermal energy
Living things use enzymes instead of a heat source of activation energy because they speed up chemical reactions as well as the metabolism in those living things.
to heat things up, to hold test tubes while the get heated (mostly to heat things up)
To heat things up. Think of it as a single burner stove. It isn't a high heat like a stove but it is effective for heating soups and similar items. You can use frying pan on them, but it isn't usually an even heat.
To heat up stuff
All snakes use heat sensors, they use them to find food, a shelter and what things are.
Thermodynamics is a study of monitoring heat rate in fluids. This helps you to assess the rate at which certain fluids heat up when exposed to warm tempratures.
Microwaves can be used for many things, but mostly heating things up that need to be re-heated or things that can actually be cooked easier and more efficently like rice and sometimes, certain tipes of steamed vegitables. Other then that, the only thing I can think of off the top of my head is to heat up milk for infants and to heat up water for tea/chocolate milk/etc...
things that uses heat are striaghtners, ovens, stoves, phones, cars and others
when tow things strike each other it get heat.
to see... and to heat things up...
Thermal Engergy: Heat engergy. Things get hotter when molecules heat up. Mechanical Engergy: This energy is in moving things.
There are heat sources in a lot of different things. A heat source is something that can heat something else up. There are heat sources in microwaves, ovens, and cars.
