Changes in ________ move matter from one state to another.
2 answers:
Answer: Option (A) is the correct answer.
Explanation:
Change in state of a substance or matter is affected by changes in kinetic energy of atoms of the matter.
More is the kinetic energy within the atoms of a matter, more easily it is able to change its state.
Also, it is known that
This relation shows that kinetic energy is directly proportional to temperature of a substance.
Hence, we can conclude that changes in temperature move matter from one state to another.

Answer:
5 moles of Argon is present in the mixture.
Explanation:
Total pressure of the gaseous mixture = 4 atm
Total number of moles = 16
Partial pressure of Ne = 2.75 atm
By Dalton's law of partial pressure, the total pressure of gaseous mixture is the sum of partial pressures of individual gases which are non-reactive.
Hence:
Also :
Partial pressure = mole fraction*total pressure
∴Number of moles of Argon = 5
Answer:
Energy: Radio Waves least, Infrared 2nd,, Blue light 3rd, Gamma Rays 4th
Wavelength: Gamma Rays smallest wavelength, Blue light 2nd, Infrared 3rd, Radio waves 4th
Frequency: Radio Waves smallest frequency, Infrared 2nd, Blue Light 3rd, Gamma Rays 4th
Explanation:
The different types of radiation are defined by the the amount of energy found in the photons. Radio waves have photons with low energies, microwave photons have a little more energy than radio waves, infrared photons have still more, then visible, ultraviolet, X-rays, and, the most energetic of all, gamma-rays.
Answer:
(a) A strong acid
Explanation:
We have given the pH of the solution is 2.46
pH=2.46
So the concentration of
solution having H+ concentration more than is acidic
Since in the given solution, H+ concentration is 0.00346 M which is more than 10^{-7}[/tex] so this is an acidic solution
Note-The concentration of decide the behavior of the solution that is, it is acidic or basic
