Energy Transfer 2
Specific Heat (Heating Capacity)
Def
Amount heat E req to raise temp by one degree per unit mass
Heat in J needed to raise temp of 1 gram by 1 degree C or K
Role in increasing different material temp
Low CP
Rapid increase temp
Less heat increase temp by one deg
High CP
Slow increase in temp
more heat to raise temp by one def
Water
High CP
Absorb lots of heat before temp rise
Regulate human body temp
Expel excess heat from body as water vaporize from lungs and sweat on skin and remove heat of vaporization from body.
Calculating Specific Heat of Foods
Siebel
Frozen ver
CP=1.256Xw+0.837
Unfrozen ver
CP = .837 + 3.349Xw
Charm
For Dairy
CP = 2.093Xf + 1.256 Xs + 4.187 Xw
Heldman and Singh
CP = 1.424 Xh + 1.549 Xp + 1.675 Xf + 0.837Xa +4.187Xw
Symbols
Xw
water content expressed as fraction
Xs
