A 10 kg iron bar (specific heat 0.11 cal/gm-oC) at 80oC is placed on a block of ice. How much ice melts?


Correct option is

1.1 kg


Iron bar will release heat till its temperature falls to 0oC. After that thermal equilibrium will be reached and ice will not melt further. If m gm be the mass of ice melted, then





The metal of a pendulum clock has a coefficient of expansion as K. Its period is 2 s at 15oC. If the temperature increases to 25oC, shall the clock:


A metal ball immersed in alcohol weighs W1 at 00C and W2 at 59oC. The coefficient of cubical expansion of the metal is less than that of alcohol. Assuming that the density of metal is large compared to that of alcohol, it can be show that:


Two straight metallic strips each of thickness t and length L are rivetted together. Their coefficients of linear expansions are   If they are heated through temperature , the bimetallic strip will bend to form an arc of radius:


A pendulum clock is 5 sec fast at temperature of 15oC and 10 seconds slow at a temperature of 30oC. At what temperature does it give the correct time?


A thermometer is graduated in millimeters. It registers – 3 mm when the bulb of thermometer is in pure melting ice and 22 mm when the thermometer is in steam at a pressure of 1 atmosphere. The temperature in oC when the thermometer registers 13 mm is:


The resistance of a resistance thermometer has values 2.71 and 3.70 ohm at 10oC and 100oC. The temperature at which the resistance is 3.26 ohm is:


The standard fixed point for temperature measurements in use today is:


A test tube containing water is placed in boiling water so that its mouth remains outside the boiling water. Choose the wrong statement:


What extinguishes a fire most quickly?


A vertical glass jar is filled with water at 10oC. It has one thermometer at the top and another at the bottom. The central region of the jar is gradually cooled. It is found that the bottom thermometer reads 4oC earlier than the top thermometers and the top thermometer reads 0oC earlier than the bottom thermometer. This happens because:
