Question

The temperature at the point  in a substance with conductivity  is  Find the rate of heat flow inward across the cylindrical

Quizplus · Accepted Answer

The rate of heat flow can be calculated using the formula Q = UAΔT, where Q is the rate of heat flow, U is the thermal conductivity, A is the area, and ΔT is the temperature difference. Since the problem provides the temperature and conductivity, the only missing piece of information is the area. Since the problem describes a cylindrical object, the area can be calculated using the formula A = 2πrL, where r is the radius and L is the length. Without knowing the dimensions of the cylinder, it is impossible to calculate the exact rate of heat flow. Therefore, the best choice is C, which admits that there is not enough information to solve the problem. Any attempt to find an exact value for the rate of heat flow would require more information.
