Identify controlled variables in the following scenario:
A grey and white car were parked in the full sun for three hours. The inside temperature was measured every hour with a digital thermometer.
- Location parked (full sun)
- Direction car faces
- Where the thermometer is placed
- 3 hours
Any other acceptable answers
Describe why filtration is not used to separate components in a solution.
Because the particles are similar sizes.
Describe what the residue to is
The component with the larger particle size that is trapped in the filter
