Question

Examine the heating curve for water below. Answer each question andcomplete the table to review your understanding of heating curves

Answer 1

Step-by-step explanation:

When the temperature is increasing, the kinetic energy change, and when the graph is horizontal (the water is changing phases), the potential energy changes.

So at A, C, and E, there is a change in kinetic energy and at B and D there is a change in potential energy.

Then, we use a specific heat capacity of 4.2 J/g°C when the water is at A, C, and E. We use latent heat of 334 J/g for melting and latent heat of 2260 J/g for evaporation.

Therefore, the complete table is
