1.Only thermal energy transfers; 'cold' is absence of thermal
energy
2.Temperature measures average kinetic energy; heat is energy
transfer
3.Metals conduct heat faster, so they feel cold by drawing heat from
your hand
4.Energy is conserved; it transforms between forms but total amount
stays constant

Use to answer form questions!
1.Specific heat = energy needed to raise 1g by 1C.
Water has HIGH specific heat (4.18 J/gC) - hard to heat up, hard to
cool down.
2.Thermal conductivity = how fast heat moves through a
material.
Metals conduct quickly; air, foam, and fiberglass conduct slowly
(good insulators).
3.Engineers select materials based on thermal properties.
Cookware needs high conductivity; coolers need low conductivity and
contents with high specific heat.
HIGH Specific Heat=Slow to Heat/Cool|LOW Conductivity=Good Insulator

Q1 (NEW):
Explain how a thermos keeps drinks hot OR cold using at least two
thermal properties.
Q2 (SPIRAL W2):
If you wanted to design a handle that stays cool on a hot pan, would
you use metal or wood? Explain using conductivity.
Q3 (INTEGRATION):
You're designing a container to keep ice cream frozen during a
summer picnic. Describe your design using specific heat,
conductivity, and heat transfer mechanisms.
