A closed bottle contains some liquid. The bottle is shaken vigorously for `5` minutes. It is found that the temperature of the liquid is increased. Is heat transferred of the liquid? Is work done on the liquid? Neglect expansion on heating.

If the temperature of a liquid is increased, then its surface tension

A closed bottle contains some liquid. We shake bottle vigorously for some time. It is found that temperature of liquid is increased (neglect expansion on heating). If Q, DeltaU and W represent heat, change in internal energy and work done, then

Name the mode of transfer of heat in the liquid

Heat in a liquid is transferred by :

Describe one experiment to show that liquids expand on heating.

Which of the following liquids does expand maximum on heating?

If temperature increases, the surface tension of a liquid

In a closed insulated container, a liquid is stirred with a paddle to increase the temperature. Which of the following is true?

A beaker containing a liquid is kept inside a big closed jar. If the air inside the jar is continuously pumped out, the pressure in the liquid near the bottom of the liquid will

A thermally insulated, closed copper vessel contains water at 15^@C . When the vessel is shaken vigorously for 15 minuts, the temperature rises to 17^@C . The mass of the vessel is 100 g and that of the water is 200 g. The specific heat capacities of copper and water are 420(J)/(kg-K) and 4200(J)/(kg-K) resprectively. Neglect any thermal expansion. (a) How much heat is transferred to the liquid vessel system? (b) How much work has been doen on this system? (c ) How much is the increase in internal energy of the system?
