PhysicsMediummultiple choice

Heat is supplied to a homogeneous sample at uniform rate. Its temperature-time graph is shown. Which conclusions follow?

Options:(select one or more)

Answer:

B, C

Solution:

On slopes, $\frac{d T}{d t} = \frac{P}{( m c )}$ . Liquid slope is smaller, so $c_{l} > c_{s}$ , B. Plateau duration is $\frac{m L}{P}$ ; the second plateau is longer, so $L_{v} > L_{f}, C$ .
