Question

Which sample has the highest temperature?

Average Kinetic Energy of Molecules (J)

1. Sample A is 1.50 x 10^4
2. Sample B is 1.73 x 10^5
3. Sample C is 2.73 x 10^3
4. Sample D is 5.06 x 10^4

Thanks in advance for your help.

Answer 1

B

....................

Answer 2

sample B is the one with the highest kinetic energy, so it should have a higher temperature

Step-by-step explanation:

The temperature of a body is related to the internal energy of a body, if the body is a gas, this internal energy is directly related to the temperature, so for the gases the energy inside a body and the temperature are directly related

An expression for this gas relation is that thermal energy equals kinetic energy

ET = K

3
`K_(B)` T = ½ m v²

T = K/3
`K_(B)`

Where ET in thermal energy and
`K_(B)` is Boltzmann's constant, in 3 it is because it is a three-dimensional system

Therefore, the body with the highest kinetic energy must have a higher temperature

When we observe your answers, sample B is the one with the highest kinetic energy, so it should have a higher temperature
