Ice is a poor conductor of heat and less dense than water. During winter, ice floats and insulates the water under it. Below the frozen layer, the water remains in its liquid state and does not freeze. Also, oxygen is trapped beneath the layer of ice. This makes it possible for aquatic animals to survive during winter.

Contained in a well lagged copper calorimeter....(Solved)
In an experiment to determine the specific latent heat of water, steam of 100⁰C was passed into water
Contained in a well lagged copper calorimeter. The following measurements were made:
-Mass of calorimeter =40g
-Mass of water + calorimeter = 135g.
-Final mass of calorimeter + water +condensed steam =148g
-Final temperature of the mixture =52⁰C.
Given that specific heat capacity of water = 4200Jkg^-1 k^-1
Specific heat capacity of copper = 390Jkg^-1 k^-1.
Determine the:
i)Mass of condensed steam
ii)The heat gained by the calorimeter and water if the initial temperature of the calorimeter and water
is 24⁰C
iii)Given that LV is the specific latent heat of vaporization of steam, write an expression for the heat
given out by steam.
iv)Determine the value of LV in (iii) above.
v)State the assumption made in the experiment.
