Question

If heat is the random kinetic energy of jiggling particles, in what way is it different to temperature?

Answer 1

temperature is degree of hotness and coldness whereas heat is energy in transit

Answer 2

Temperature is THE AVERAGE INTENSITY OF MOTION of the molecules. But HEAT is THE OVERALL QUANTITY of Kinetic energy.

Good question! Temperature is INTENSIVE while HEAT is accumulated- EXTENSIVE

Answer 3

Given how we mention temperature, surely some of the jigglings cancel out vectorially also?

Answer 4

Again: temperature is related (not actual \[E_{KIN}\] but a function of it} to the kinetic energy of a "typical" molecule. Like , say, average income of a US citizen/
While HEAT is the OVERALL SUM of ENRGIE-S - like the overall GDP of the country

Answer 5

they do cancel out but temperature gives us an average

Answer 6

Kinetic energy is a scalar, and positive one only !

Answer 7

Yes, but for temperature

Answer 8

Sorry ghazi - You mislead people. Kinetic ENRGIES DO NOT CANCEL EACH OTHER !

Answer 9

The are NOT-vectors and , not cancel each other!

Answer 10

i am not talking about kinetic energy and fyi please go through the dynamics of heat vectors

Answer 11

I understood that before! But can opposite KEs reduce the temperature?

Answer 12

Sorry man - henpen asked specifically about temperature, and it is A SCALAR.
NO henpen -YOU HAVE BEEN MISLEAD (AS I expected) KE CANNOT CANCEL EACH OTHER

Answer 13

KE only ADD and ACCUMULATE

Answer 14

ANd HEat, my dear ghazi IS NEVER A VECTOR !!!!!!

Answer 15

talking about it at a molecular level heat is function of collision of molecules too kindly take that into consideration..i do agree KE is of course a scalar quantity but you can't ignore mean velocity factor that accounts for develope heat by the way thanks @Mikael

Answer 16

No, you have been mislead into thinking that I have been mislead. This is my question.
