+ 2 X a X 7.5
a = - 10.82
/15
a =- 7.7776 ms-1
F = ma = 1 X -7.7776 ms-1
F = -7.7776 N

- In an experiment to determine the specific latent heat of vaporization of water, steam of mass 20g at 100°C is passed into 200g of water...(Solved)
In an experiment to determine the specific latent heat of vaporization of water, steam of mass 20g at 100⁰C is passed into 200g of water initially at 40⁰C in a container of negligible heat capacity. The temperature of the water rises to 80⁰C. (take the specific capacity of water 4200J/kg/k and the boiling water as 100⁰C)
i. Determine the specific latent heat of vaporization of water.
ii. What are the two errors in this experiment?
