What is the specific heat of a substance if 1560 cal are required to raise the temperature of a 312-g sample by 5 degrees celsius?
A) 0.033 cal/g*C
B) 0.33 cal/g*C
C) 0.99 cal/g*C
D) 1.33 cal/g* C

0.33 cal/g*C

Explanation:

The amount of heat required is determined from the formula

q

=

m

c

Δ

T

,

where

q

is the amount of heat transferred

m

is the mass of the substance

c

is the specific heat capacity of the substance

Δ

T

is the change in temperature

q

=

1560 cal

m

=

312 g

Δ

T

=

15 °C

c

=

q

m

Δ

T

=

1560 cal

312 g × 15 °C

=

0.33 cal⋅g

-1

°C
