The amount of energy in molecules of matter determines the state of matter. Matter can exist in one of several different states, including a gas, liquid, or solid state. ... A gas is a state of matter in which atoms or molecules have enough energy to move freely.
Answer:A property that changes if the amount of substance changes
Explanation:
This is the answer
Answer:
The frequency of this light is
.
Explanation:
Wavelength of the light = ![\lambda = 430 nm=4.30\times 10^{-7} m](https://tex.z-dn.net/?f=%5Clambda%20%3D%20430%20nm%3D4.30%5Ctimes%2010%5E%7B-7%7D%20m)
Speed of the light = c = ![= 3\times 10^8 m/s](https://tex.z-dn.net/?f=%3D%203%5Ctimes%2010%5E8%20m%2Fs)
Frequency of the light = ![\nu](https://tex.z-dn.net/?f=%5Cnu%20)
![\nu =\frac{c}{\lambda }](https://tex.z-dn.net/?f=%5Cnu%20%3D%5Cfrac%7Bc%7D%7B%5Clambda%20%7D)
![\nu =\frac{3\times 10^8 m/s}{4.30\times 10^{-7} m}=6.98\times 10^{14} s^{-1}](https://tex.z-dn.net/?f=%5Cnu%20%3D%5Cfrac%7B3%5Ctimes%2010%5E8%20m%2Fs%7D%7B4.30%5Ctimes%2010%5E%7B-7%7D%20m%7D%3D6.98%5Ctimes%2010%5E%7B14%7D%20s%5E%7B-1%7D)
The frequency of this light is
.
