I would like some help with keywords. So far, I have:
- Metal
- Glass
- Styrofoam
- Plastic
- Paper
- Refrigeration
- Insulation
- Temperature
- Conductor
- Heat
- Energy
The things I would like to know are:
- Are these keywords correct?
- What other keywords can you think of?
- Are there any sites that you know that I can search for more keywords?
Please help.
