The conversation between human and AI assistant.
Do the melting and freezing points have to be same for any substance?
That makes sense. What about the effect of pressure on melting and freezing points?
Pressure can also have an effect on the melting and freezing points of a substance. In general, the higher the pressure, the higher the melting point and the lower the freezing point. This is because pressure affects the way that molecules interact with each other, making it more difficult for them to break apart when a solid is heated or when a liquid is cooled.
