    physics paper 1,2 ........can we discuus da papper nw?

    Exactly and you can see only 2/3p is decreasing...the other answers were p which is the same....2p means double...3/2p is also more....from tat way itself you see that it's the answer

    physics paper 1,2 ........can we discuus da papper nw?

    Use p*v=p*v since it is constant temperature The pressure at the start is P and 200 cm3 When the valve is open the gas spreads and the volume occupied is 200+100=300cm3....and let the pressure be x which we need to find 200P=300x X=200/300 P X=2/3 P

    ATP for Physics

    Repeat the reading several times Take the average of the values Keep out side factors constant...(this varies from experiment to another just put a sensible one to make the experiment fair) When answering the questions think what are the possible human errors and suggest how to avoid it THESE...
