A constant pressure air thermometer gave a reading of 47.5 units of volume when immersed in ice cold water, and 67 units in a boiling liquids. The boiling point of the liquid will be

If the temperature of an object is 140^oF, then its temperature in centigrade is

Of the following thermometers, the one which can be used for measuring a rapidly changing temperature is a

On centigrade scale, the temperature of a body increases by 30^oC. The increase in temperature on Fahrenheit scale is

When the room temperature becomes equal to the dew point, the relative humidity of the room is

When a copper ball is heated, the largest percentage increase will occur in its

A vertical column 50 cm long at 50^oC balances another column of same liquid 60 cm long at 100^oC. The coefficient of absolute expansion of the liquid is

The apparent coefficient of expansion of a liquid when heated in a copper vessel is C and when heated in a silver vessel is S. If A is the linear coefficient of expansion of copper, then the linear coefficient of expansion of silver is

A uniform metal rod is used as a bar pendulum. If the room temperature rises by 10^oC, and the coefficient of linear expansion of the metal of the rod is 2 × 10^–6 per ^oC, the period of the pendulum will have percentage increase of

A bar of iron is 10 cm at 20^oC. At 10^oC, it will be (α of iron = 11 × 10^–6/^oC)
