  • Me: You have a 15g piece of metal that is heated up at 180*c. You place this piece of metal in a calorimeter that holds 40g of water at 25*c. The calorimeter reads a temperature of 30*c as the highest temp. what is the specific heat of the metal?

DATA:

Mass of metal = 15g

∆T = 180C0 – 30C0 = 150C0

SOLUTION:

∆Q = mC∆T

For Q

Specific heat capacity of water = 4.186J/gC0

1g water = 4.186J

40g = (4.186*40)

  = 167.44 J

∆Q = mC∆T

C = ∆Q/ m∆T

C = 167.44/(15*150)

C = 0.07441J/gC0
