  1. Day 7: • Element Quiz #2 • Packet O Fun:Use notes to fill in pg. 2 & bottom of pg. 4. • Specific Heat! • CW/HW: Specific Heat Questions pg 8-9

  2. Specific Heat • Specific Heat = Energy needed for 1 gram of the substance to raise 1°C • cal/g°C or J/g°C • Water’s specific heat = 4.184 J/g°C or 1.000 cal/g°C.

  3. Specific Heat Capacities

  4. Q = Cp x m x ∆T • Q = heat (Joules) • Cp = specific heat (J/g°C) • m = mass • ∆T = change in temperature (Tfinal – initial) (°C)

  5. Hg has a specific heat of 0.139 J/g°C. How much heat is required to raise the temperature of a 22.80 grams sample from 16.2°C to 32.5°C?

  6. How many joules of heat are required to raise the temperature of 200 grams of water from 20.0°C to 50.0°C?
