A heat source is defined as something that generates its own heat, such as an electric heater or fire. In contrast, items like socks, blankets, and coats do not produce heat but rather provide insulation. The document provides a list of various examples asking if they qualify as heat sources.

1. Heat Sources!
What’s a heat source? What
isn’t?

2. Heat Source!
A heat source is something
that makes it’s own heat!

3. For Example…
An ELECTRIC HEATER is a heat source! It
makes heat and can warm up a
room!
A pair of socks is NOT a heat source.
Though socks can help keep your feet
warm, they don’t make their own
heat. They simply use INSULATION to
keep your feet warm.
