According to the kinetic molecular theory, the correct answer is:
c) have an average kinetic energy proportional to the temperature in Kelvin.
What is kinetic molecular theory
The kinetic molecular theory is about how gases behave. It makes assumptions about the tiny particles in gases. Based on this idea:
Particles in an ideal gas do not stick together very much.
The theory says that gas particles don't stick together or push each other apart very much.
The particles of a perfect gas are not close together. The theory says that gas particles are always moving around randomly and are far apart from each other.
The speed of gas particles is equal to the temperature in Kelvin. The theory says that the energy of gas is related to its temperature. As the heat goes up, the gas particles move faster.
According to the kinetic molecular theory, the particles of an ideal gas
a) attract one another strongly.
b) are packed closely together.
c) have an average kinetic energy proportional to the temperature in Kelvin.
d) all of the above.
