Question

How would the volume of helium in a balloon be affected if the balloon was placed in a room where air temperature is lower?

Answer 1

Step-by-step explanation:

So,when balloon filled with helium gas was placed in lower temperature we will observe that the volume of the helium gas inside the helium will decrease due to which size of the balloon will also get decreased.

This is because volume is directly proportional to the temperature of the gas at constant pressure and number of moles. And this law is known as Charles law of

`V\propto T` (At constant pressure and number of moles)

Answer 2

The volume will decrease.

Step-by-step explanation:

According to Charles' Law, the volume of a gas is directly proportional to its temperature.

V = kT

Thus, if T decreases, V decreases.
