What causes the thermometer with the wet sock to read lower than the thermometer with the dry bulb?
The rate of evaporation of water from the wet side, this is how relative humidity is measured. As the water evaporates it effectivly 'uses' some of the heat energy which would otherwise be heating the thermometer. The higher the relative humidity (water saturation of the air) the less water can evaporate and the lower the difference between the wet and dry side.
What cause wet bulb to read lower than dry bulb?
Evaporation of the water in the wet bulb fabric cover causes the temperature of the wet bulb to go down. When the air is dry, more water will evaporate, and when the air is saturated, less will evaporate.

What will the mercury thermometer show when it is kept in ice?
The question must be asked carefully. If the thermometer is in water ice and there is no liquid water, and there is one atmosphere of pressure, the thermometer can read anything from the freezing point of water and lower, depending on the range of the thermometer. If the thermometer is in a stable mix of water and ice, it will read the freezing point of water.
What are precautions that are to taken while measuring the temperature in clinical thermometer?
