Physics 105, Fall Term, 2009
1) Temperature is a
measurement of speed of moving particles.
2) Heat is defined as the ability to
change the thermal equilibrium of another object, not how hot or cold the
3) Increasing the heat of almost all objects
will cause them to expand.
If you have difficulty understanding what the difference is between
temperature and heat, here is a 5 minute corny video that does a really good
job of explaining the difference:
What is the measure of the degree of hotness?
What is the measure of the quantity of hotness?
If object A has a higher temperature than object B, but object B has a
higher heat than object A, which object would be able to melt more ice
Not enough information to tell
The picture below is of a railroad track that was constructed in the winter.
This picture was taken in the middle of the day in July.
Explain why the track looks like this.
The temperature increased from the time the railroad track was built, so it underwent thermal expansion. Because the track is made of a single piece of metal and is bolted down to the ground at several parts, the only way for it to expand is by curving and bowing.
Will an object expand more or less if it has a higher coefficient of thermal
The comments entered in these last two boxes go into a big anonymous data file that I will use to guide the lectures of the day. That means two things:
1) If you have a specific question or concern and would like an individual
answer you will need to come by the office or send an email.
2) If you really want to get an anonymous comment to me before the lecture, it
must be submitted before 11am that day.
Was there anything that you didn't understand in the reading assignment?
What was confusing to you?
