    You can calculate using formula W=nRT ln P1/P2

    eduncle-logo-app

    Data is given to you

    eduncle-logo-app

    yes

    eduncle-logo-app

    but in this question can I take volume and temperature constant

    eduncle-logo-app

    as it's ideal process

    eduncle-logo-app

    yes when u find heat absorbed then q=U +W

    eduncle-logo-app

    U becomes 0

    eduncle-logo-app

    what is u

    eduncle-logo-app

    it's 0 n

    eduncle-logo-app

    internal energy

    eduncle-logo-app

    yes

    eduncle-logo-app

    in ideal gas or process we can take temp.and volume cons.

    eduncle-logo-app

    right

    eduncle-logo-app

    According to question

    eduncle-logo-app

    but for ideal gas volume is always constant

    eduncle-logo-app

    you know for ideal gas...PV is constant when T is constant

    eduncle-logo-app

    boyles law

    eduncle-logo-app

    So different conditions different question u have to proceed like that

    eduncle-logo-app

    yes sir I know this

    eduncle-logo-app

    U telling this thing ...this is true one mole of ideal gas will occupy a volume of 22.4 L at STP

    eduncle-logo-app

    But in numerical solving...according to ques..you proceed

    eduncle-logo-app

    ok sir

    eduncle-logo-app

    calculate and change J into cal

    eduncle-logo-app

    😊👍

    eduncle-logo-app

    already calculated sir

    eduncle-logo-app

    very good👍👍

    eduncle-logo-app

    but internal enegy 0

    eduncle-logo-app

    yes

    eduncle-logo-app

    temp is constant na it occurs at 100°C

    eduncle-logo-app

    sir

    eduncle-logo-app

    yes Shweta
