Q=MCΔTQ= HeatM=MassC= Specific Heat CapacityΔT=Change in Temperature
Mass Who has more mass?Who generate more heat? Remember Q=MCΔT
Mass• Does outer space have mass?• Does air have mass? Remember egg and can.
Specific Heat Capacity• This is just the amount of heat absorbed per gram for each degree rise in temperature.
Specific Heat Capacity• How many of you drink coffee?• How many of you take a bath instead of a shower?• What if people were made of metal?
ΔT=Change in Temperature• If an object undergoes a change in temperature from 99-98 Celsius, and an identical object undergoes a change in temperature from 50 to 40 Celsius, then which object gave off the most heat?
Q=MCΔT (Biol link)• What happens when people heat up?• What happens when they cool?• Hint (people are mostly made of water)
Q=MCΔTHow do bodies of water stabilize temperature?
Q=MCΔT• If M= 5 grams• C=1 calorie/(gram*celsius)• ΔT=1 degree• What is Q?• What if M= 10 grams?
