Answer 1

For equal masses and initial temperatures, substance B, with the highest specific heat capacity, will contain the most heat and require more energy to raise its temperature by the same amount. It will also penetrate the least into a wax slab due to its higher specific heat capacity.

Step-by-step explanation:

The amount of heat contained in a substance is related to its mass, specific heat capacity, and temperature. For substances A, B, and C with equal mass and equal initial temperature, the one with the highest specific heat capacity would require the most energy to raise its temperature by the same amount, hence would have the highest amount of heat for the same temperature increase. The specific heat capacity is the amount of energy needed to increase the temperature of 1 kilogram of a substance by 1°C. Substance B, with a specific heat capacity of 470 J/kg°C, would have the most heat content for an equal mass and equal temperature increase compared to substances A and C.

When it comes to raising the temperature by an equal amount, the substance with the highest specific heat capacity will require more energy. Therefore, substance B needs more heat to raise its temperature by an equal amount, as it has the highest specific heat capacity (470 J/kg°C). Finally, if all substances are solid and have equal mass, the one with the highest specific heat capacity will penetrate the least into a wax slab when heated to 200°C because it will absorb more heat without increasing its temperature as much as the others.
