Question

A 50.0 g sample of copper is at 25.0°C. If l 200 I of energy is added to it by heat, what is the final temperature of the copper?

Answer 1

35,4°C

Explanation:

i suppose 200 J of energy
from the relation:
`Q= m xx c_p xx Delta T`
we have (cp= specific heat of copper)
`Delta T= Q/(m xx c_p) = (200J)/( 50 g xx 0,385 J/(g °C))=10,4°C`
The final temperature will be 25,0+ 10,4 = 35,4°C
