If earth suddenly stops rotating about its own axis, the increase in it’s temperature will be

Latent heat of ice is 80 cal/g. A man melts 60 g of ice by chewing in 1 minute. His power is

A faulty thermometer has its lower fixed point marked as —10°C and upper fixed point marked as 110°. If the temperature of the body shown in this scale is 62°, the temperature shown on the Celsius scale is

If there are no heat losses, the heat released by the condensation of x g of steam at 100°C into water at 100^oC can be used to converty g of ice at 0^oC into water at 100^oC. Then, the ratio y : x is nearly

The figure shows a glass tube (linear coefficient of expansion is α) completely filled with a liquid of volume expansion coefficient γ. On heating length of the liquid column does not change. Choose the correct relation between γ and α

Two thermometers are used to record the temperature of a room. If the bulb of one is wrapped in wet hanky

A pendulum clock keeps correct time at 0°C. Its mean coefficient of linear expansions is α /°C, then the loss in seconds per day by the clock if the temperature rises by t°C is

The coefficient of apparent expansion of a liquid when determined using two different vessels A and B ate γ_{1 and γ2 respectively. If the coefficient of linear expansion of the vessel A is α, the coefficient of linear expansion of the vessel B is}

The coefficient of volume expansion of a liquid is 49 × 10^–2 K^–1. Calculate the fractional change in its density when the temperature is raised by 30°C.

A clock with a metal pendulum beating seconds keeps correct time at 0°C. If it loses 12.5 s a day at 25°C, the coefficient of linear expansion of metal pendulum is
