Answer:

Use the formula ∑X/N to calculate the arithmetic mean. After this, we calculate the deviations of all the observations from the mean value using the formula D= X-mean. Here, D = deviation of an item that is relative to mean. It is calculated as D = X- mean.

) 40 g of ice at 0° C is used to bring down the temperature to 40° C of a certain mass of water at 60° C. Find the mass of water used.(Specific heat capacity of water = 4200 Jkg-1 °C-1, latent heat of fusion of ice = 336 x 103 Jkg )​

Explanation:

in cgs,

s of water = 1

latent heat of fusion = 80

principle of calorimetry,

heat lost = heat gain

by water = by ice

m x 1 x ( 60- 40) = 40 x 80 ( melt) + 40 x 1 x ( 40-0)

m x 20 = 4800

m = 240g
