2
Q
why does convection not happen in solids?
A

3
Q
what happens when you heat a liquid?
A
- the particles closest to the heat gain kinetic energy.
2.these particles spread out and become less dense, they also rise to the top.
3.the cooler particles go down and when heated they go up creating a cycle called convection current.
4
Q
