Question

Water has a specific heat of 4.184
J/Kg°C. Wood has a specific heat
of 1.760 J/Kg°C. What material
needs more energy to raise the
temperature 1°C
a.) wood b.) both are the same c.) water

Answer 1

Answer:

Water.

Explanation:

This means:

1) For the temperature of water to raise at any point to the next degree by 1°C, will require a specific heat capacity of  4.184  J/Kg°C

2) For the temperature of wood to raise at any point to the next degree by 1°C, will require a specific heat capacity of  1.760  J/Kg°C

Note that: specific heat is directly proportional to energy, therefore the higher the heat capacity, the higher the energy.

4.184  J/Kg°C is higher than 1.760  J/Kg°C, hence WATER needs more energy.
