In a laboratory, liquid in a thermally insulated container is stirred for one, `hr`, by a mechanical linkage to a in surrounding, for this process:

`W lt 0 , q=0`

`W lt 0 , q gt 0`

`W gt 0 , q=0`

Text Solution

Verified by Experts

The correct Answer is:

`W= +v` because work done on system.
`W=0` because thermally insulated container.

An ideal gas is enclosed in a thermally insulated container. Container is covered by an insulating piston which is connected with spring. Small displacement is given to piston as shown in figure. Which of the following statements is correct? Neglect friction everywhere.

A 0.60 kg sample of water and a sample of ice are placed in two compartmetnts A and B separated by a conducting wall, in a thermally insulated container. The rate of heat transfer from the water to the ice through the conducting wall is constant P, until thermal equilibrium is reached. The temperature T of the liquid water and the ice are given in graph as functions of time t. Temperature of the compartments remain homogeneous during whole heat transfer process. Given specific heat of ice =2100 J//kg-K , specific heat of water =4200 J//kg-K , and latent heat of fusion of ice =3.3xx10^5 J//kg . Initial mass of the ice in the container equal to
