Assertion:Ethylene glycol is added to water and used as antifreeze in the radiators of auto-mobiles. Reason: Addition of ethylene glycol lowers the freezing point of water.

Most substances contract on freezing. However, water does not belong to this category. We know that water expands on freezing. Further, coefficient of volume expansion of water in the temperature range from 0^(0)C to 4^(0)C is negative and above 4^(0)C it is positive. This behaviour of water shapes the freezing of lakes as the atmospheric temperature goes down and it has an extremely important effect on plant and animal life in lakes. If the atmospheric temperature is below 0^(0)C :

The amount of ice that will separate out on cooling the solution containing 50g of ethylene glycol (CH_2OH)_2 in 200 g of water at -9.3^@C is

This behaviour of water shapes the freezing of lakes as the atmospheric temperature goes down and it has an extremely important effect on plant and animal life in lakes. If the atmospheric temperature is below 0^(0)C and ice begins to form at t = 0, thickness of ice sheet formed up to a time .t. will be directly proportional to

In a 10 metre deep lake, the bottom is at a constant temperature of 4^(0)C . The air temperature is constant at -4^(0)C . The thermal conductivity of ice is 3 times that of water. Neglecting the expansion of water on freezing, the maximum thickness of ice will be

This behaviour of water shapes the freezing of lakes as the atmospheric temperature goes down and it has an extremely important effect on plant and animal life in lakes. Under fixed atmospheric conditions, if it takes 2 hr. to form a 1 cm thick layer of ice in a lake, time taken for the thickness of ice layer to grow further by 1 cm will be

Ice starts freezing in a lake with water at 0^(0)C when the atmospheric temperature is -10^(0)C . If the time taken for 1 cm of ice to be formed is 12 minute, the time taken for the thickness of the ice to change from 1 cm to 2 cm will be
