What is the specific heat of a metal substance if 135 kJ of heat is needed to raise 4.1 kg of the metal from 18.0°C to 37.2°C?
The specific heat of a metal.
Answer to Problem 10P
Solution:
The specific heat of a metal is 1715 J/kgK
Explanation of Solution
Formula Used:
The formula used is the relation between temperature and specific heat from thermodynamics
Where,
is the heat transferred
is the specific heat
is the mass
is the final temperature
is the initial temperature
Given:
is 135kJ or 135000 J
is to be determined
is 4.1 kg
is 37.2 C
is 18 C
Calculation:
Inserting the given values in the heat capacity formula:
J/kgK
