If we double the average kinetic energy of the gas atoms, what is the new temperature in ∘c?

-- Take the original temperature in °C .

-- Add 273.

-- Double the number you have now.

-- Subtract 273.  Now you have the new temp in  °C .

if kinetic energy is doubled than temperature of the gas must be double

Explanation:

As we know that average kinetic energy of the gas atom is known as

here we know that

f = degrees of freedom

R = ideal gas constant

T = temperature of the gas

now we know that average kinetic energy of the gas is double that of initial value

so from above formula we can say that kinetic energy is directly proportional to the temperature of the gas

so here if kinetic energy is doubled than temperature of the gas must be double

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.

scattering of light by tiny particles in air to produce the colors we see on sky, is dependent on the following factors:

(i) wavelength of light

(ii) size of the scattering particle  

(iii) distance traveled by light through the atmosphere.

according to rayleigh's law of scattering, the amount of scattering is inversely proportional to the fourth power of its wavelength. shorter the wavelength, greater is its scattering. hence violet/blue light is scattered more than red.

sun's light is a composite light ( visible light) with wavelengths in the range 400 nm (violet) to 700 nm (red). as sunlight passes through our atmosphere, the molecules of air scatter light according to their wavelengths. during sunrise and sunset, the sun's position is below the horizon. hence light from the sun travels a greater distance in the atmosphere when compared to its position a noon.

as sunlight enters the earth's atmosphere, blue light is scattered away and at the end of its journey in the sky, only red and orange wavelengths remain in the beam.

hence at sunrise and sunset, the sky appears reddish orange.
