Question

Determine the heat needed to warm 25.3 g of copper from 22 degrees celsius to 39 degrees celsius.

Answer 1

The heat needed to warm 25.3 g of copper from 22°C to 39°C is 165.59 Joules.

Step-by-step explanation:

`Q=mc\Delta T`

Where:

Q = heat absorbed or heat lost

c = specific heat of substance

m = Mass of the substance

ΔT = change in temperature of the substance

We have mass of copper = m = 25.3 g

Specific heat of copper = c = 0.385 J/g°C

ΔT = 39°C - 22°C = 17°C

Heat absorbed by the copper :

`Q=25.3 g* 0.385 J/g^oC* 17^oC=165.59 J`

The heat needed to warm 25.3 g of copper from 22°C to 39°C is 165.59 Joules.
