As the temperature of a gas increases, the average kinetic energy of the gas particles increases and the average speed of a gas particle increases.
According to the kinetic theory of gases, all gases are made of microscopic molecules that move in straight lines until they bump into another gas molecule or object. This transfer of energy causes molecules to move around faster and bump into each other more.
Kinetic energy is proportional to the speed of the molecules. As the speed of the colliding molecules increases, so does the total kinetic energy of all the gas molecules. It's pretty difficult to measure the speed of an individual gas molecule.
Instead, temperature can be used as a measure of the average kinetic energy of all the molecules in the gas. As the gas molecules gain energy and move faster, the temperature goes up. This is why Amy feels warmer!
To determine the average kinetic energy of gas molecules, we need to know the temperature of the gas, the universal gas constant (R), and Avogadro's number (NA).

Kinetic energy has increased.
The <em>Kinetic Molecular Theory</em> of gases states that the average kinetic energy of the molecules of a gas is directly proportional to its Kelvin temperature.
Thus, if the temperature of the air in a room has increased, the average kinetic energy of its molecules has increased.

Answer: The maximum wavelength of light for which a carbon-chlorine Single bond could be broken by absorbing a single photon is 354 nm
Explanation:
The relation between energy and wavelength of light is given by Planck's equation, which is:
where,
E = energy of the light =
(1kJ=1000J)
N= avogadro's number
h = Planck's constant
c = speed of light
= wavelength of light

Thus the maximum wavelength is 354 nm
Answer: 12.18 u
Explanation: The average atomic mass of an element is calculated by taking the weighted average of the atomic masses of its stable isotopes.
In other words, each stable isotope will contribute to the average mass of the element proportionally to its abundance.
