Question

Heat capacity of a substance is given by C = BT^2, where T is in degree Fahrenheit and the value of B is 50, what is the value of B if T is in degree Celsius?

(a) 81

(b) 25

(c) 162

(d) 100

This question was addressed to me in an interview.

Enquiry is from Temperature topic in portion Temperature and Pressure of Basic Chemical Engineering

Answer 1

The correct choice is (c) 162

For explanation I would say: TF = 9TF/5 + 32 => coefficient of T^2 in C will be B*(9/5)^2 = 50*81/25 = 162.
