Could someone please set out the entire experiment to calculate the latent heat of vaporisation/fusion for water.

Please include all details including all measurements that taken.

 Please go into as much detail as possible, this is to help me with the Paper 3 & 6 phy.



Also please explain how a SLIP RING commutator works.
