Two vessels are labeled $A$ and $B$. Vessel A contains $\mathrm{NH}_{3}$ gas at $70^{\circ} \mathrm{C},$ and vessel $\mathrm{B}$ contains Ne gas at the same temperature. If the average kinetic energy of $\mathrm{NH}_{3}$ is $7.1 \times 10^{-21} \mathrm{J} /$ molecule, calculate the meansquare speed of Ne atoms in $\mathrm{m}^{2} / \mathrm{s}^{2}$

$$4.24 \times 10^{5} m^{2} / s^{2}$$

In physics, a gas is one of the three major states of matter (the others being liquid and solid). A gas is a fluid that does not support tensile stress, meaning that it is compressible. The word gas is a neologism first used by the early 17th-century Flemish chemist J.B. van Helmont, based on the Greek word ("chaos"), the simplest of all the elemental forms of matter.

In physics, thermodynamics is the science of energy and its transformations. The three laws of thermodynamics state that energy can be exchanged between physical systems as heat and work; that the total energy of a system can be calculated by adding up all forms of energy in the system; that energy spontaneously flows from being localized to becoming dispersed, spread out, or uniform; and that the entropy of an isolated system not in equilibrium will tend to increase over time, approaching a maximum value at equilibrium.

He is for mola for, for a trot, mean square velocity, pi r m s is equal to under root 3 r t divided by m 3 r d under root m we have here, t is equal to 70 degrees. Centigrade is equal to 3. He 43 kelvin molar mass of neon is equal to 20.18 gram per mole is equal to 0.02018. Kg per mole is equal to 8.314 joule per kelvin per mole. Putting these values into the formula so we have root. Mine square velocity is equal to 3 into 8.31 joule per kelvin per mole into 343 kelvin divided by 0.02018 kg per mole is equal to 4.24 multiply 10 raised to the power 5 joule per k. We know that 1 joule is equal to 1 kg in 2. Meter square out of second square joule per k g is equal to k. G into metric square square divided by k. G is equal to m square divided by s square per second square. So here we have values. 4.24 multiply 10 raised to the power 5 joule kg is equal to 4.24 multiply 10 raised to the power 5 meters square per second square is equal to 4.24. Multiply 10 raised to the power 5 meter square per second square.
