Which object has the highest temperature? (see chart below)

Object Kinetic Energy Of Molecules (J)

a 1.50 x 10^4

b 1.73 x 10^5

c 2.73 x 10^3

d 5.06 x 10^4

Answers:

(a) object C

(b) object A

(c) object B

(d) object D

I can't see the chart.

But by kinetic energy theory, the temperature is a measure of the average kinetic energy of the particles.

So a low kinetic energy would depict a low temperature and a high kinetic energy would depict a high temperature.

So from this theory the particle with the highest temperature would be the one with the highest kinetic energy.

And that is by b, with a value of 1.73 x 10^5 J.

(c) object B
