Question

A piece of ice at -10 °C is sealed in an insulting container and is constantly heated to 50 °C water Which of the following statements is correct? a) The temperature rises monotonically because ice and water are the same compound. b) The temperature rises monotonically because it is heated constantly. c) The temperature rises monotonically because no heat is lost to surrounding (in an insulting container.) d) The temperature does not rise monotonically because ice and water have different densities. e) The temperature does not rise monotonically because a phase change occurs at a fixed temperature. f The temperature does not rise monotonically because ice and water have different values of specific heat.

Answer 1

The answer is e

Step-by-step explanation:

The correct statement is: e) The temperature does not rise monotonically because a phase change occurs at a fixed temperature.

As the ice is constantly heated, it will absorb heat and undergo a phase change from solid (ice) to liquid (water) at its melting point (0 °C). During this phase change, the temperature remains constant until all the ice has melted. After the ice is completely melted, the temperature will resume rising. This non-monotonic behavior is due to the energy required for the phase transition from ice to water.
