Question

How much heat is needed to change the temperature of a 30.0 gram sample of copper from 20.0c to 60.0c?

Answer 1

Answer: 462.00 Joules of heat will be needed to change the temperature of copper from 20° C to 60° C.

Step-by-step explanation:

Mass of copper,m = 30.0 grams

Specific heat capacity of copper,c =
`0.385 J/g ^oC`

`T_1=20^oC,T_2=60^oC`

`\Delta T=T_2-T_1=60^oC-20^oC=40^oC`

`Q=mc\Delta T`

`Q=30.0 grams* 0.385 J/g ^oC* 40^oC=462.00 J`

462.00 Joules of heat will be needed to change the temperature of copper from 20° C to 60° C.
