Question

(b) Why does increasing the temperature cause a solid substance to change in suc- cession from a solid to a liquid to a gas?

Accepted Answer

Hey everyone in this example, we're asked why does a solid substance transition from a solid to a liquid to a gas when the temperature rises? So according to the prompt, we're going from a transition of solid to liquid and then from liquid to gas. And we are told that this corresponds to a rise in temperature. We want to recall that an increase in temperature corresponds to an increase in average kinetic energy, and so therefore our particles will overcome the inter molecular attractive forces and we'll have a less ordered state. So what we have recalled here below would be our final answer to explain why the transition from solid to liquid to gas occurs with an increase in temperature. So I hope that everything I reviewed was clear. If you have any questions, leave them down below and I will see everyone in the next practice video.
