Question

Which sample has the lowest temperature?

Sample A

Sample B

Sample C

Sample D

heres a table
Sample Average Kinetic Energy of Molecules(J)
A 1.50×104
B 1.73×105
C 2.73×103
D 5.06×104

Answer 1

i think it is A ? right since it has the lowest average kinetic energy and temperature is related to kinetic energy?

Answer 2

Temperature is defined as the average kinetic energy of a molecule

\(T ∝KE_{ave}\)

Hence, the one with the greatest average KE is the answer.

Answer 3

oh I mean lowest KE, it's asking for lowest temp lol

Answer 4

it would then be A ,correct?since it is the lowest?

Answer 5

Isn't C smaller?

Answer 6

i thought 1.50x^4 would be smaller?

Answer 7

no, it's bigger. You could expand them if you want.
\(1.73\cdot10^{4} >1.50\cdot10^{3}\)

Answer 8

you seem to have the numbers confused, wouldnt we compare , c which is C 2.73×10^3 and A what i think it is which is A 1.50×10^4 ?

Answer 9

A 1.50×104 smallest
B 1.73×105 second largest
C 2.73×103 third largest
D 5.06×104 largest

Answer 10

this is what im thinking, unless im making mistake ,:/ im not quite sure

Answer 11

your exponents seem to be different then whats given

Answer 12

Hold on

so are the sample values as follows?

A - \(1.50\cdot10^{4}\)
B - \(1.73\cdot10^{5}\)
C - \(2.73\cdot10^{3}\)
D - \(5.06\cdot10^{4}\)

Answer 13

yes ,that is correct

Answer 14

So wouldn't \(2.73\cdot10^{3}\) be the smallest?

Answer 15

in standard it would be 2,730 , and a which is what i was thinking would be 173000. ohh okay so yes it would be the smallest

Answer 16

that makes sense now, thank you!
