Heat and Specific Heat, Relaxation time (8points) 11. The molar specific heat of many materials at low temperatures is found to obey the Debye law $c_v = A[T/\theta]^3$ where A is a constant equal to $1.94 \times 10^3$ J mol$^{-1}$ K$^{-1}$ and with the Debye temperature $\theta$ taking different values for different materials. For diamond, it is 1860K. (5points) a. Evaluate $c_v$ at 20 K and 120 K b. How much heat is required to heat one mole of diamond between 20 K and 120 K? c. What is the average molar specific heat in this range?
A tank with some water in it begins to drain. The function v ( t ) = 40 − 2.5 t determines the volume of the water in the tank (in gallons) given a number of minutes t since the water began draining. What is the vertical intercept of v ?
