Question

Can some one walk me through Gas laws and help we with some problems?

Answer 1

@SeanStewart16

Answer 2

Okai so for the first one
There is no change of temperature mentioned, thus we consider the temperature to be constant.
Therefore PV= constant.
P1V1 = P2V2
So use that and take the answer !

Answer 3

For the second one
V1/T1 = V2/T2
Because pressure is constant !

Answer 4

Third one the volume is kept constant , therefore
P1/T1 = P2/T2

Answer 5

4th one use the combines gas law ! ( as they have given

Answer 6

5th one
PV = nRT
P pressure pascals
V volume in Litres
R universal gas constant
T temperature in Kelvin ! Now substitute the values and get the answer !

Answer 7

okay so i just plug in and make both sides equal?

Answer 8

Answer 9

yep yep !
