Question

Copper has a specific heat of 0.386 J/g°C. How much heat is required to increase 5.00 g of copper from 0.0°C to 10.0°C?

A 3.86 J
B 5.00 J
C 10.0 J
D 19.3 J

Answer 1

the answer is 19.3 j

Answer 2

Answer: D) 19.3 J

Step-by-step explanation:

Using the equation below:

`Q= m* c* \Delta T`

Q= heat gained by copper = ?

m= mass of copper = 5.0 g

`\Delta T` = change in temperature =
`(10-0)^0C=10^0C`

c = heat capacity of copper = 0.386 J/g ° C

Putting in all the values we get:

`Q=5g* 0.386J/g^0C* 10^0C`

`Q=19.3Joules`

Thus heat gained by 5 g of copper is 19.3 Joules.
