Question

The average kinetic energy in a substance is called
Select one:
a. temperature.
b. cold.
c. thermal energy. ***
d. heat.
I put c. but my test said a. was right.
This is confusing to me, as I think c. would have been correct, according to what my textbook had clearly stated. Can someone explain, please?

Answer 1

If it helps, here's what the textbook said: "The thermal energy of a substance is the total kinetic energy of all the particles it contains."

Answer 2

"total K.E." vs. "average K.E."

temperature is the average K.E.

Answer 3

Temperature is described as "a measure of how hot or cold matter is" and that was the only explanation for temperature.
"Average" is used with "total" interchangeably throughout the whole lesson/textbook, so I don't get it.

Answer 4

you and two friends get on a scale (shipping)

is your total weight the same as your average weights

google this ... "what is temperature in science"

Answer 5

That's annoying, since that is definitely NOT the way my lesson put it! Thanks for helping me understand.

Answer 6

can you guys tell me what the answers are please

Answer 7

for me all the answers r c ;-;

Answer 8

1. Temperature.
2. the average speed of particles increased.
3. Heat flows from hot to cold and is the transfer of thermal energy.
4. The molecules will have more potential energy because of their arrangement.

Answer 9

And cheers to living well and a good future. (rigged but who cares we ALL beat the system :)

Answer 10
