Question

A student heats a beaker containing ice and water. He measures the temperature of the contents of the beaker as a function of time.Which of the following would correctly represent the result?

• A. Ice and water are equilibrium.
• B. Temperature does not change.
• C. Temperature of water increases
• D. Initially temperature of the content of beaker does not rise.because of latent heat of fusion.

Answer 1

The correct option is D Initially temperature of the content of beaker does not rise.because of latent heat of fusion.

Figure (d) represents the result correctly.

Explanation: Initially temperature of the content of beaker does not rise, because of latent heat of fusion. When all ice melts and, the temperature of content starts rising, hence, figure (d) represents the result correctly.
