Calorimetric Formulas –

P1V1 P2V2 = T1 T2

No Phase Change: Q = m(ΑT)

Pressure Formula: P = F A

Latent Heat of Fusion: Q = mΑHfus

Mass-Energy Formula: E = mc 2

Latent Heat of Vaporization: Q = mΑHvap

Constants Volume of Ideal Gas at STP: 22.4

L mol

Speed of Light in a Vacuum: c = 3.00 × 108 m s Specific Heat of Water: (H 2O) = 1.00 cal = 4.18 J (g ºC) (g ºC) J Latent Heat of Fusion of Water: ΑHfus(H 2O) = 80 cal g = 334 g J Latent Heat of Vaporization of Water: ΑHvap(H 2O) = 540 cal g = 2260 g

Unit Conversions Calorie-Joule Conversion: 1 cal = 4.184 J Absolute Temperature Conversion: K = ºC + 273 Pressure Conversions: 1 atm = 760 mm Hg = 760 Torr = 101.325 kPa = 14.7 lbs.2 = 29.92 in. Hg in. Copyright © 2003 California Department of Education
