Question

whoever tells right answer with explanation will get brainliest mark

Answer 1

PV=nRT

now from above conditions the equation will become,

V=RT

but R=constant

so, V directly proportional to T

hence straight line is sure.

since m(slope) =R(positive)

so ,slope will also be positive hence (4) option is incorrect,

now just solve eq., V=RT

1stly, putting T=273K

So, V will be 22.4l

(2) option has been terminated,

Now similarly put T=373K

So, V will come as 30.6l

So answer is(3)
