Question

Copper has specific heat of o.385 J/ [g×°C). A piece of copper absorbs 5o00 J of energy and undergoes a temperature change from 100 C to 200 'C . What is the mass of the piece of copper?​

Answer 2

q = mC∆T

q = heat = 5000 J

m = mass = ?

C = specific heat = 0.385 J/gº

∆T = change in temp = 200 - 100 = 100º

solving for m (mass) we have...

m = q /(C)(∆T) = 5000 J /(0.385 J/gº)(100º)

m = 130
