Question

The specific heat of copper metal is 0.385 J/(g × °C). How much energy must be added to a 35.0 gram sample of copper to change the temperature from 20.0°C to 65.0°C? (2 points)
270 J
809 J
606 J
1130 J

Answer 1

Q = mC∆T 

where: 
q = heat 
m = mass of substance = 35.0 grams 
C = 0.385 J/g*C 
∆T = change in temperature = 65C - 20C = 45C 

q = (35.0 g)*(0.385 J/g*C)*(45C) = 606 J
