    How to Calculate Vapor Pressure of Isooctane at 25°C?

    I think I got it. The vapor pressure should equal to 1 atm since boiling point is the temperature where the vapor pressure equals the surrounding's pressure or the atmospheric pressure. Thanks a lot!

    Calculating Energy Absorption of 2.0kg Bag of Ice

    A 2.0 kg bag of ice is used to keep a cooler of pop cold for 5.5 h. If the ice had an initial temperature of -4ºC and, after 5h, was liquid water with a temperature of 3ºC, find the power of energy absorption. Any help would be great. I don't know where to start:confused:.

    Frictional Force: Find Accel. of 3kg & 2kg Blocks

    I think, One thing you could do is that, find the force of friction and then find then thr net force, after that since you have the net force and the mass, you can find acceleration.

    Calculating Kinetic Energy for a Swinging Wrecking Ball

    A wrecking ball, with mass of 315kg, hangs from a crane on 10.0m of cable. If the crane swings the wrecking ball so that the angle that the cable makes with the vertical is 30.0º, what is the potential energy of the ball in relation to its lowest positio? What will be the kinetic energy of the...
