Question

Select the correct answer. A piece of wood near a fire is at 23°C. It gains 1,160 joules of heat from the fire and reaches a temperature of 42°C. The specific heat capacity of wood is 1.716 joules/gram degree Celsius. What is the mass of the piece of wood?
A. 16 g B. 29 g C. 36 g D. 61 g

Answer 1

The mass of the piece of wood is 36 g

Explanation:

The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.

$Q=m\times c\times \Delta T$

Q = Heat absorbed= 1160 Joules

m= mass of substance = ?

c = specific heat capacity = $1.716J/g^0C$

Initial temperature = $T_i$ = 23°C

Final temperature = $T_f$  = 42°C

Change in temperature ,$\Delta T=T_f-T_i=(42-23)^0C=19^0C$

Putting in the values, we get:

$1160=m\times 1.716\times 19^0C$

$m=36g$

The mass of the piece of wood is 36 g
