Question

What is true of a sample of gas as temperature is increased?

Answer 1

Answer:

The particles move faster, and their average kinetic energy increases.

Explanation:

When the temperature of gases increases the reaction rates will increase. Molecules of gases will be furnished with higher kinetic energy. Kinetic energy is directly proportional to temperature. Increase in temperature causes the frequency of ordinary collisions and effective collisions per unit time to increase. This leads to a surge in kinetic energy too.

Answer 2

Answer: The particles move faster, and their average kinetic energy increases.

Explanation:

Kinetic energy is the energy possessed by an object by virtue of its motion.

Average kinetic energy is defined as the average of the kinetic energies of all the particles present in a system. It is determined by the equation:

$K=\frac{3RT}{2}$

K= kinetic energy

R= gas constant

T= temperature  

From above, it is visible that kinetic energy is directly related to the temperature of the system.

So, if temperature is more, average kinetic energy of the system is more and thus speed of the molecules will be more.Thus the molecules will move faster.
