Explanation:
Most molecules survive for long periods of time at room temperature because at room temperature, they are stable. The room temperature is the temperature between 20-25°C where human beings are the most comfortable.
At the room temperature, most molecules are in their natural physical state without any reason to rearrange their bonds and a times be destroyed. The energy at room temperature is just perfect for bond stability.

Deuterium has one proton and one neutron, 12H, while tritium has one proton and two neutrons, 13H.
I believe the correct answer would be that t<span>he change in enthalpy can be found by adding the enthalpies of the individual thermochemical reactions of a chemical reaction.</span> In Hess' Law, enthalpy is independent of the mechanism of the reaction. The enthalpy should be the sum of all the changes in the reaction.
<span>The average speed of the gas is related to the kinetic
energy of the gas. The kinetic energy of
the gas is also related to the temperature of the gas. If the average speed of
the gas is closer to zero, it means that it has very low motion or kinetic
energy. This can be inferred that the gas has a very low temperature. At absolute
zero, the motion of all the gas molecules stops. This means that the kinetic
energy of the gas is also zero. Zero kinetic energy means zero average speed.</span>
<span>So, the answer is cylinder B. The average speed of the gas
in cylinder B is closest to zero.</span>
