What happens in the space above the soft drink in a closed bottle or can as the soft drink warms to room temperature

As the refrigerant begins to warm up to room temperature, the air inside the bottle that is between the refrigerant and the bottle cap begins to slowly come down. As you might already imagine, air in contact with the liquid can generate bubbles, and this is what happens when the air in the bottle starts to drop as the soda heats up.

Explanation:

You have seen that at room temperature it is common for soda to overflow bubbles. This is because the air inside the soda bottle begins to come down and when it comes in contact with the liquid causes a lot of bubbles and can even make the soda overflow.

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.
