A sample of an ideal gas is cooled from 50.0°C to 25.0°C in a sealed container at constant volume.
1 answer:
Answer: Option (E) is the correct answer.
Explanation:
Since, it is given that the container is sealed one. So, no gas molecule is able to escape into the surrounding. Therefore, average molecular mass of the gas will remain the same.
Also, it is given that gas is cooled down from to
. This means that there occurs a decrease in kinetic energy of the molecules of gas as kinetic energy is directly proportional to temperature.
Mathematically,
Hence, sped of molecules will decrease and molecules become closer to each other with decrease in temperature.
Thus, we can conclude that following values for the gas will decrease.
- The average distance between the molecules.
- The average speed of the molecules

When formaldehyde and acetone then react with each other( aldol condensation) then it will be formed <u> methyl vinyl ketone.</u>
<u />
In organic chemistry, an aldol condensation would be a condensation reaction in which an enol and enolate ion combines with a carbonyl chemical to produce a -hydroxy aldehyde or -hydroxy ketone, that is then dehydrated to produce a conjugated enone.
In aldol condensation, when formaldehyde and acetone then react with each other then it will be formed <u> </u><u>methyl vinyl ketone.</u>
It can be written as
→
When it will be heated then it gives methyl vinyl ketones.
→
So, the pair of reactants will be formaldehyde and acetone
