Question

Which statement is true for a heating curve?

Answer 1

The correct option is B.

A heating curve refers to a graphical representation of how the temperature of a compound change when heat is added to it. The graph shows the phase transition that a substance undergoes as heat is added to it. The plateaus on the curve represent the critical temperature points where phase changes actually occur. The curve has two axes, the vertical and the horizontal axes. The temperature of the substance is typically plotted on the vertical axis while the time during which heat is applied is plotted on the horizontal axis.

Answer 2

I think it shows how the temperature of a substance changes when heated
