Complete the table and sort the wavelengths
1 answer:
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: HBr has the lowest rate of effusion at a given temperature.
Explanation: The effusion rate usually increases with increase in temperature because the kinetic energy of the gaseous molecules increases. But it was not true for gases having heavier mass. This was explained by Graham's Law.
Graham's Law states that the rate of effusion of a gas is inversely proportional to the square root of its molecular weight.
We are given different gases with different Molecular masses. The gas having larger Molecular mass will have the lowest rate of effusion.
Mol. Mass of = 80 g/mol
Mol. Mass of = 16 g/mol
Mol. Mass of = 17 g/mol
Mol. Mass of HBr = 81 g/mol
Mol. Mass of HCl = 36 g/mol
As, Mol. mass of HBr is the highest, so its rate of effusion will be the lowest.
