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?

Answer 1

Answer: D)  19.3 J

Explanation:

Using the equation below:

$Q= m\times c\times \Delta T$

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:

$Q=5g\times 0.386J/g^0C\times 10^0C$

$Q=19.3Joules$

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

Answer 2

The answer is 19.3 j
