A diver has a lung capacity of 2.4 L when the pressure is 0.8 atm. What is the volume of the diver’s lungs when the pressure cha
tangare [24]

Answer:

The final volume is 1.6 L.

Explanation:

It is given that,

A diver has a lung capacity of 2.4 L when the pressure is 0.8 atm. We need to find the volume of the diver’s lungs when the pressure changes to 1.2 atm. Let V₂ is volume.

It is based on Boyle's law. According to this law,

PV=K

K is constant

P_1V_1=P_2V_2

V_2=\dfrac{P_1V_1}{P_2}\\\\V_2=\dfrac{0.8\times 2.4}{1.2}\\\\V_2=1.6\ L

So, the final volume is 1.6 L.

What type of bond will form between two chlorine atoms?
Trava [24]
Since both atoms are the same and are both nonmetals, they would form a Nonpolar covalent bond. This bond occurs when usually atoms of the same element or atoms of propriety electronegativity differences are sharing electrons to form bonds. There is an equal sharing of valence electrons in this chemical bond.

vekshin1

Answer:

See explanation

Explanation:

We know that photosynthesis involves the combination of carbon dioxide and water in the presence of sunlight to yield glucose.

If the atmosphere is rich in carbon dioxide such as  in a green house where air is filled with carbon dioxide, the rate of photosynthesis is increased.

As the rate of photosynthesis is increased, the growth of plants is also increased.

Hence, in a greenhouse where the air contains more carbon dioxide, the rate of plant growth increases.
