A balloon is filled with 35.0 L of helium in the morning when the temperature is 35.00 oC.
nexus9112 [7]

Answer: V = 33.9 L

Explanation: We will use Charles Law to solve for the new volume.

Charles Law is expressed in the following formula. Temperatures must be converted in Kelvin.

V1 / T1 = V2 / T2 then derive for V2

V2 = V1 T2 / T1

= 35 L ( 308 K ) / 318 K

= 33.9 L

zhuklara [117]

Answer:

Option D is correct.

Explanation:

Compared to a sample of helium at STP, the same sample of helium at a higher temperature and a lower pressure because any gas at a higher temperature and a lower pressure will  behaves like  an ideal gas. for eg.

nitrogen at STP show its behavior as an ideal gas.

When pressure of a gas increased & temperature is decreased then the gas does not follow ideal gas law.

Therefore option D is correct.
