What change would occur in the kinetic energy of vapor if a container of vapor is placed at 0 Kelvin?
A.The kinetic energy of gas particles will increase.
B.The kinetic energy of gas particles will decrease.
C.The kinetic energy of gas particles will remain unchanged.
D.The gas particles will have no kinetic energy.
The kinetic energy of gas particles will be transferred to the container.

D. The gas particles will have no kinetic energy.
At absolute zero temperature (0 Kelvin), all molecular motion stops, resulting in the gas particles having no kinetic energy.
To determine the change in kinetic energy of vapor when placed at 0 Kelvin, we need to understand the relationship between temperature and kinetic energy.
According to the kinetic theory of gases, the average kinetic energy of gas particles is directly proportional to the temperature of the gas. In other words, as the temperature increases, the kinetic energy of the gas particles also increases, and vice versa.
0 Kelvin, also known as absolute zero, is the lowest possible temperature on the Kelvin scale. At this temperature, the particles of a substance would have a minimum possible amount of kinetic energy.
So, in this scenario, when a container of vapor is placed at 0 Kelvin, the kinetic energy of the gas particles will decrease significantly. Therefore, the correct answer is B: The kinetic energy of gas particles will decrease.
