Final answer:

The rate of heat flow through the wall of a house does not depend on the specific heat capacity of the wall material, but it is affected by dimensions, thickness, temperature differences, and thermal conductivity.

Step-by-step explanation:

The rate of heat flow through the wall of a house does not depend on the specific heat capacity of the wall. This is because the specific heat capacity is relevant to the amount of energy required to raise the temperature of the material but does not affect the conduction rate. Factors that do affect the heat flow are the dimensions of the wall, the thickness of the wall, the temperatures outside and inside the house, and the thermal conductivity of the wall. These quantities are involved in the calculation of the rate of heat transfer (Q/t), where thermal conductivity (k), surface area (A), thickness (d), and temperature difference (T2 - T1) come into play. The dependence of heat transfer on these quantities can be illustrated by the formula Q/t = k * A *(T2 - T1)/d, which shows that the rate of heat transfer is proportional to the area and temperature difference, and inversely proportional to the thickness.
