Answer:
The heat needed to warm 25.3 g of copper from 22°C to 39°C is 165.59 Joules.
Explanation:
[tex]Q=mc\Delta T[/tex]
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 :
[tex]Q=25.3 g\times 0.385 J/g^oC\times 17^oC=165.59 J[/tex]
The heat needed to warm 25.3 g of copper from 22°C to 39°C is 165.59 Joules.
