2. Mass
Who has more mass?
Who generate more heat? Remember Q=MCΔT
3. Mass
• Does outer space have mass?
• Does air have mass? Remember egg and
can.
4. Specific Heat Capacity
• This is just the amount of heat absorbed
per gram for each degree rise in
temperature.
5. 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?
6. 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?
7. Q=MCΔT (Biol link)
• What happens when people heat up?
• What happens when they cool?
• Hint (people are mostly made of water)
