Question

What is the specific heat of a substance if 1560 cal are required to raise the temperature of a 312-g sample by 15°C?

A) 0.033 cal/g°c
B) 0.33 cal/g°c
C) 0.99 cal/g°c
D) 1.33 cal/g°c

Answer 1

The specific heat capacity the substance is calculated using the below formula

Q(heat) = Mc delta T
Q =1560 cal
m(mass) 312 g
delta T (change in temperature ) = 15 c
C= specific heat capacity=?

by making c the subject of the formula
c=Q/m delta T
= 1560 cal/ 312g x 15 c = 0.33 cal/g/c (answer B)
