300 K to 600 K. The pressure of the gas doubled.
The number of moles of gas will be
(a) 5
(b) 2.5
(c) 10
(d) 20​

Answer 1

Answer:

Option A is al right

Explanation:

V1=5

T1=300

P1=p or 1 atm

V2=?

P2=2p or 2 atm

T2=600

according to gas laws,

P1V1/T1=P2V2/T2

P×5/300=2P×V×600

P×5×600=2P×V×300

P×5×600/2P×300=V

V=5 MOLES
