Question

1.2 kg ice at 0°C is mixed with 1 kg water at 24°C in a closed calorimeter. The fraction of ice that melts is

Answer 1

Answer:

The fraction of ice that melts is 0.25.

Explanation:

Let m be the of mass of ice that melts.  

As we know,

$m_{1}L=m_{2} S\triangle T$

Given,

$m_2 = 1 kg\\s = 1 cal/g C\\L = 80 Cal/gm\\\triangle T=24^{0} C$

Where, L is the latent heat.

Now,

$m_1(80) = 1*(1)*(24)\\m_1 = 0.3 kg$

Thus, the fraction of ice that is melt,

$f = \frac{0.3}{1.2}\\f = 0.25$

Therefore, the fraction of ice that melts is 0.25.
