The heating curve could describe processes such as boiling, condensation and freezing.
What is a heating curve?
A heating curve is a plot or graph wherein a substance is subjected to increasing temperature against time to measure the amount of energy it absorbs and changes state with increasing temperature.
Which processes could the heating curve be describing?
- boiling. Yes, since matter goes from liquid to gas.
- condensation. Yes, since matter goes from gas to liquid.
- endothermic reaction. No, since phase changes are physical changes.
- exothermic reaction. No, since phase changes are physical changes.
- freezing. Yes, since matter goes from liquid to solid.
