Question

What is the specific heat of iron, if it requires 1050 J of heat energy to raise the temperature of 220.0 g of iron from 10.0oC to 20.4oC?

Answer 1

Answer: The specific heat for iron is
`0.459J/g^0C`

Step-by-step 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* c* \Delta T`

Q = Heat absorbed= 1050 Joules

m= mass of substance = 220.0 g

c = specific heat capacity = ?

Initial temperature =
`T_i` = 10.0°C

Final temperature =
`T_f` = 20.4°C

Change in temperature ,
`\Delta T=T_f-T_i=(20.4-10.0)^0C=10.4^0C`

Putting in the values, we get:

`1050=220.0* c* 10.4^0C`

`c=0.459J/g^0C`

The specific heat for iron is
`0.459J/g^0C`
