anonymous · Answer

P1 V = nRT

P1 = 20 * 300 * 8.3 / 10

anonymous · Answer

didnt get...so that temp remains constant?

anonymous · Answer

ok...it's fine...it's leaking slowly so no change in temp.

anonymous · Answer

p1 = 4980

anonymous · Answer

again use work done for an isothermal process.

anonymous · Answer

is p1 = 4980 i used R = 8.314

anonymous · Answer

but wat's ur unit for p1?

anonymous · Answer

R = 8.314 J mol K

anonymous · Answer

yes...i agree...but wat's ur unit for p1?

anonymous · Answer

i think...u'll look for p1 in atm caz p2 is also in atm...or u can chage both p1 and p2 to some other unit.

anonymous · Answer

use R= 0.0821 lit atm/mol/K

anonymous · Answer

then u'll get p1 in atm.

anonymous · Answer

ok...I m not doing the calculation
