The units for free fall acceleration
What is m/s^2?
100
It is the equation to find acceleration.
What is a=(vf-vi)/t or the change in speed/ change in time

Explain why metals expand when they are heated.

Thermal expansion occurs because a material's atoms vibrate more as its temperature increases. The more its atoms vibrate, the more they push away from their neighboring atoms. As the space between the atoms increases, the density of the material decreases and its overall size increases.

How is conduction and convection different?

Conduction occurs in solids that are touching/have contact.

Convection occurs in fluids (liquids/gases), warmer particles have less mass and rise - cooler particles have more mas and sink
