Question

1)How is the kinetic energy related to the temperature of a gas in the Kelvin scale?

2)When would a gas have zero kinetic energy?

3)How do you convert between degrees Celsius and degrees Fahrenheit?

Answer 1

1- Temperature is a number that is related to the average kinetic energy of the molecules of a substance. Temperature can be measured on the Kelvin Scale. That is the relationship to kinetic energy.

2- A gas, or any matter, would have zero kinetic energy when its temperature reaches absolute zero, zero degrees Kelvin. While such matter is theoretically possible, it has never been observed since any observations of such matter would require some sort of energy transfer, which would be impossible for a substance with zero kinetic energy.

3-
-Take the temperature in Celsius and multiply 1.8.-
-.Add 32 degrees.
-.The result is degrees Fahrenheit.

Answer 2

Yes, for monatomic perfect gas, (1/2) m v^2 = (3/2) k T

so the kinetic energy of a molecule is proportional to the absolute temperature (o K)
