    counterexample for boiling point: I saw that boiling point will increase because: more energy is required for the solvent's vapor pressure to reach the external pressure. counterexample for freezing point: Because of increasing the pressure, which prevents water molecules properly arranging...

    Relationship between magnitude of current and magnetic field

    then example if the "magnitude" of the 1st conductor has a bigger magnetic strength of 10 and the 2nd conductor is 5, so in the end they will exert a magnetic force of magnitude 5 on each other ?

    What happens when a conducting sphere rubs against metal?

    I think there will not be a fixed charge on conducting material

    What happens when a conducting sphere rubs against metal?

    I know that metal is a "reservoir" of electrons, whereby electrons can flow out and in easily, so when conducting sphere is rubbed against metals, is there even a resulting charge on the conducting sphere?

    How to find the heat energy produced in a resistor?

    i found current to be 2/5 A. then 2/5A multipled by 6s = 2.4C. and since one joule per coulomb is equal to the unit of p.d, i get 2.4J. I don't get 4.8J(supposed answer)

    Finding the potential difference between 2 points in a circuit

    2V=5kohms 2kohms= 0.8V 3kohms=1.2V. p.d across P and Q= 1V-0.8V=0.2V is this explanation not sufficient ?
