What is heat?
Heat is thermal energy that flows between
objects due to a difference in temperature.

What is thermal conductivity?
Thermal conductivity is the ability
of a material to transfer heat.
When is heat waste?
Cars will stop working if they cannot release their extra heat.
Main Idea
A candle is placed on a steel block and begins
to melt. How do you know whether the candle
or the steel block is hotter?
Heat must flow into a candle in order
for it to melt. If heat is flowing into the
candle, it must be cooler than the steel
block.

Conclusions
An infrared image of a house
shows that the roof is brighter
than the rest of the house. What
does this mean?
The roof is
radiating
more heat
energy.

What is volume?
Volume is the loudness of a sound.
What is echolocation?
Finding objects by using sound
waves is known as echolocation.
Main Idea
How could a stereo playing loudly rattle
dishes?
The vibrations from the speakers could travel
as sound waves through the air and hit the
dishes. The sound energy from the wave
could then vibrate the dishes.
