2. Which state of matter—solid, liquid, or gas—is the best at conducting heat? Why?

Best at conductioning heat- Solid

Explanation:

In order for heat to conduct it has to pass from particle to particle.

A solid has particles closely compacted so the heat is able to tranfer quickly from particle to particle.

A liquid has isn't as compacted it actually has enough space to slide over each other

A gas has very far apart particles and takes heat longer to transfer from one particle to another.
