The mass of a particle is 2.2x10⁻¹⁵ kg

Consider smoke particles as an ideal gas

The translational RMS speed of the smoke particles is 2.45x10⁻³ m/s.

<em>v= √3kT/m</em>

<em>where k= 1.38x10⁻²³J/K, T is 288K, and m is the mass of the smoke particle</em>

<em>2.45x10⁻³ = √3x1.38x10⁻²³x288/m</em>

<em>m= 2.2x10⁻¹⁵ kg</em>

Therefore, the mass of a particle is 2.2x10⁻¹⁵ kg.

Must new substances be formed when you observe a chemical property? Explain
castortr0y [4]
Yes. It is rather a natural phenomenon. If you search and understand the process of chemical change or reaction that results to its chemical property outcome, it has a new formed substance. Unlike physical change or reaction it only changes in shape or form but the substance, compound or element in the matter is till the same. Furthermore, when chemical change is undergoing you notice the change in shape, size and from like the physical change but there is a change in the element, compound or substance. When you lit a fire on a paper the fire disorients, disorganizes and disturb the former positions of the atoms and because of the fire as catalyzer the atoms did its behavior –changing both intrinsic and extrinsic.
