While a balloon is being filled, if the temperature of the air in the balloon decreases, what happens to its volume?

It decreases

Explanation:

Charle's Law: This law states that volume is directly proportional to the temperature of the gas at constant pressure and number of moles.

    (At constant pressure and number of moles)

where,

= initial volume of gas  

= final volume of gas

= initial temperature of gas

= final temperature of gas

Therefore, as volume and temperature are proportional, if the temperature of the air in the balloon decreases,  its volume also decreases.

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.

its a 5.5 n
