Question

Which type of objects should not be kept on the pan?
A. Wet
B. Dry
C. Cold
D. Hot

Answer 1

Heat is the form of energy which produces in us the sensation of coldness or hotness. Taking heat and thermal expansion and testing every option in the condition where it transfers the heat from higher to lower energy level. Then, explaining what effect damages or bad effect on it.

Complete step-by-step answer:
Heat is the energy of molecular motion which is equal to the sum of the total kinetic energy possessed by the molecules of the body. While heat is energy, temperature is a measurement of how hot or cold something is.
Most materials are likely to be a thermal expansion; it’s a tendency to expand when heated and to contract when cooled. Thermal expansion happens when an object expands and becomes larger due to some change in the object's temperature. All four objects expand when heated and exist in liquids, solids, and gases. The S.I. unit of heat is joule J
Taking part A:
Wet objects take away the thermal energy (heat) and are likely to meltdown or evaporate on the pan. It damages the pan's lifespan for cooking.
Taking Part B:
Dry objects are ideal on the pan as they are harder for thermal energy to pass on to objects in equilibrium. They don’t melt, evaporates, it does burn the object when kept for long
Taking Part C:
Cold object is the same as wet; it takes the thermal energy (heat) of the pan away and makes the object evaporate or meltdown into the liquid. It does take away heat energy faster and damages the lifespan of the pan.
Taking Part D:
Hot objects are likely to be placed on the pan as the energy transfer from pan to object will carry on without any interruption. Pan is made to withstand a limit of heat that cannot reach in daily life.
Thus, the final result is options A and B: wet and cold.

So, the correct answer is “Option A and B”.

Note: When a liquid is heated, it expands, irrespective of the temperature range. However, water is an exception. When water at ${{0}^{\circ }}C$ is heated, it contracts till${{4}^{\circ }}C$, instead of expanding. This anomalous behavior of water was explained by Thomas Charles Hope.
