Question

the difference between the boiling point and the freezing point of pure water at standard pressure is
(1)32 K
(2)273 K
(3)100 K
(4)373 K

Answer 1

water boils at 100 degrees celsius
water freezes at 0 degrees celsius
1 K = 273 degrees celcius

all you have to do is calculate the K value for 0 celcius and the K value for 100 degrees celcius and subtract to find the difference :)

Answer 2

thanks :) so its (3) right ?

Answer 3

373 K -273 K = ??K
