Answer : The new volume of the air is, 6.83 L
Explanation :
Charles' Law : It states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,

where,
are the initial volume and temperature of the gas.
are the final volume and temperature of the gas.
We are given:

Putting values in above equation, we get:

Therefore, the new volume of the air is, 6.83 L
Answer:
the answer is B.Construction
Explanation:
Black coffee since it is a darker colour and has a heavier taste
Answer : The correct option is, (d) inversely proportional to volume and directly proportional to the kelvin temperature
Explanation :
Boyle's Law : It is defined as the pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.

Charles' Law : It is defined as the volume of the gas is directly proportional to the temperature of the gas at constant pressure and number of moles.

Gay-Lussac's Law : It is defined as the pressure of the gas is directly proportional to the temperature of the gas at constant volume and number of moles.

Combined gas law : It is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,

or,

From the above information we conclude that the pressure exerted by a gas is inversely proportional to volume and directly proportional to the kelvin temperature.
Hence, the correct option is, (d)
