The average kinetic energy and rms speed of N₂ molecules at STP is 
and 
Given,
The average kinetic energy of a molecule is given by, 
where k is the Boltzmann constant and Tis the absolute temperature of the gas.
The rms speed of 
molecules is given by
The average kinetic energy of a gas's particles is inversely related to its temperature. As the gas warms, the particles must travel more quickly since their mass is constant.
The average kinetic energy (K) is equal to one half of the mass (m) of each gas molecule times the RMS speed (vrms) squared.

Answer:
The final volume of NaOH solution is 30ml
Explanation:
We all know that
V1S1 = V2S2
or V1= V2S2÷S1
or V1= V2×S2×1/S1
or V1=100×0.15×1/0.50
V1= 30
∴30 ml NaOH solution is required to prepare 0.15 M from 100ml 0.50 M NaOH solution.
Answer:
The definition of physical science is the sciences concerned with the study of inanimate natural objects, including physics, chemistry, astronomy, and related subjects.
Explanation:
Answer:
Coefficients represents no of moles while subscripts represent no of atoms.
Answer:
1000 g
Explanation:
d = m/v
We are given d: 10g/cm3
and v: 100cm3
Plug them into the equation to get 10 = m/100
Then, cross multiply 10x100 to get mass which is: 1000g
