Question

The specific heat capacity of graphite is 0.71 J/g°C. Calculate the energy required to raise the temperature of 750 g of graphite by 160°C.

Show your work.

Answer 1

Q=mcdeltaT
Q=(750)(0.71)(160)
Q=85200j

Answer 2

Answer : The energy required will be, 85200 J

Solution :

Formula used :

`Q=m* c* \Delta T`

where,

Q = heat required = ?

m = mass of graphite = 750 g

c = specific heat capacity of graphite =
`0.71J/g^oC`

`\Delta T=\text{Change in temperature}` =
`160^oC`

Now put all the given values in the above formula, we get heat required.

`Q=(750g)* (0.71J/g^oC)* (160^oC)=85200J`

Therefore, the energy required will be, 85200 J
