On the Dal lake of Kashmir, a layer of 2 cm thick ice is formed when the outside temperature is `-10^@C` . How much time it will take for the increase in thickness of ice by 0.5 mm? Take, Density of ice `= 1 g//c^3` m
Latent heat of ice = 80 cal/g
Thermal conductivity of ice = `0.008 cal s^(-1) cm^(-1) ""^@C^(-1)`

Explanation

To solve the problem of how much time it will take for the increase in thickness of ice by 0.5 mm on the Dal Lake of Kashmir, we can follow these steps:

### Step 1: Convert the thickness increase to centimeters
The increase in thickness of ice is given as 0.5 mm. We need to convert this to centimeters for consistency with the other measurements.
\[ 0.5 \text{ mm} = 0.05 \text{ cm} \]
