Xg = 20X seconds
120*20x = specific heat of vaporization * X
specific heat ........ = 2400X/X = 2400kJ/kg

Thanks A@di ;D

The function of a slip ring is to make one or more continuous electrical connections from points in a stationary unit to points in a rotating section. Electrical connections on slip rings can be for both power and data signal connections.

ok this is Charles' Law
The volume of a fixed mass of gas is directly proportional to its temperature if the pressure is kept constant
meaning there is an increase in volume due to the temperature rise because the pressure is constant
so here the change in vol. in b)i) is only possible because the pressure is kept constant .. so no change

There is this experiment in oct nov 2006 question 5 (b) how do you carry it out? what do you have to draw, the MS is not clear.. can someone please do it for me?

So Boyle's Law is that if temperature is constant, then when volume decreases, pressure increases?
