Unit 7 Formula Sheet

= m / V density
P = W / t power
1 watt = 1 J/s
Q = m c T       c = specific heat capacity
Q = m L       L = latent heat
TK = TC + 273
TF = 32 + TC * 9/5
L = L T
V = V T
3       volume expansion coefficient
Q / t = A T / L       Heat conduction; L is the length
Prad = A T4       Heat radiation; 
emissivity 1, 
= 5.67*10-8 W/(m2*K4)
P A / R2       Power recieved by area A at distance R from a point source 
Latent heat of vaporization of water at 100o C = 540 cal/g
Latent heat of melting ice at 0o C = 80 cal/g
1 calorie equals 4,186 Joules
Material Specific Heat Capacity near 0o C, cal/(g*K) Termal Conductivity at 0o C, W/(m*K)
