4) What volume will the gas in the balloon at right occupy at 250k?

balloon: 4.3L 350K

2.87 liter.

Explanation:

Given:

Initially volume of balloon = 4.3 liter

Initially temperature of balloon = 350 K

Question asked:

What volume will the gas in the balloon occupy at 250 K ?

Solution:

By using:

Assuming pressure as constant,

V∝ T

Now, let  K is the constant.

V = KT

Let initial volume of balloon , = 4.3 liter

1000 liter = 1 meter cube

1 liter =

4.3 liter =

And initial temperature of balloon, = 350 K

Let the final volume of balloon is

And as given, final temperature of balloon, is 250 K

Now,

Dividing equation 1 and 2,

K cancelled by K.

By cross multiplication:

Now, convert it into liter with the help of calculation done above,

Therefore, volume of the gas in the balloon at 250 K will be  2.87 liter.

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying
