Q.2 Choose the Correct Answer from the Following 1- According to Fourier's law of heat conduction, the rate of heat transfer by conduction depends upon a. area of cross section normal to the heat flow b. temperature gradient c. both a. and b. d. none of the above 2- Why is the negative sign introduced in the equation of Fourier's law of heat conduction? q = -kA(dT/dx) a. because heat transfer rate is inversely proportional to temperature gradient b. because the value of thermal conductivity k is negative c. because heat is transferred from higher temperature to lower temperature d. none of the above 3- The materials which have low thermal conductivity are called thermal insulators. 4- The unit of the rate of heat transfer is d) Watt. 5- The temperature distribution in a large thin plate with uniform surface temperature will be d) Linear.
