The pressure of the sample of gas at 273 K is equal to 0.273 atm assuming the volume is constant.
Gay-Lussac's law can be described as that when the volume of the gas remains constant then the pressure (P) of the gas and the absolute temperature (T) in a direct relationship.
Gay Lussca's law can be described as mentioned below:
P/T = k
The pressure of gas is directly proportional to absolute temperature of the gas.
P ∝ T ( Volume of gas is constant)
or, P₁/T₁ = P₂/T₂ .................(1)
Given, the initial temperature of the gas, T₁ = 400 K
The final temperature of the gas, T₂ = 273 K
The initial pressure of the gas, P₁ = 0.40 atm
The final pressure of the given gas can be calculated from Gay Lussac's law as:
P₂ = (0.40/400) ×273
P₂ = 0.273 atm
Therefore, the pressure of this gas at 273 K is 0.273 atm.

a lithosphere
a biosphere
a cryosphere
the answer is bioshere
Answer:
A biosphere
Explanation:
Biosphere refers to the zone of life on a planet. It includes all living elements of a planet. It is also known as Eco-sphere and includes the interaction of all living being with their surrounding.
Of all the planets and exo-planets, Earth is the planet known to have life and thus biosphere.
Whereas atmosphere, lithosphere and cryosphere can be found on other planets as well.
Atmosphere: Layer of air and gases surrounding a planet or any celestial object. (Except Mercury, all the planets of solar system have atmosphere)
Lithosphere: it refers to the rigid outer part of the planet which includes crust and mantle. (All the rocky planets have lithosphere)
Cryosphere: portion of the planets where water is in ice form. (Many exoplanets have been discovered having cryosphere)
