Important Questions on Physical Environment
Do you think the height of the mercury columns in the two thermometers given in the figure have been shown correctly? Give reason for your answer.
Look at the height of mercury columns in the thermometers shown in the figure. Can you say liquid in which container A or B is at higher temperature?
Table 1- The table shows the readings of two thermometers dipped in ice-water.
| A | B | |
| Height of mercury column | Same as B | Same as A |
| The degree of warmth expressed by the number at the height reached by the mercury column. (L) |
Table 2- The table shows the readings of two thermometers placed above boiling water.
| A | B | |
| Height of mercury column | Same as B | Same as A |
| Greater extent of hotness expressed by the number at the height where the mercury column has raised. (U) |
Fill in the following table by taking data from Table-1 and Table-2.
| A | B | |
| Number written after dipping the bulb of the thermometers in ice-water (L) | ||
| Number written after putting the bulb of the thermometers above boiling water (U) | ||
| U-L | ||
| In how many parts should we divide the region between two marks so that each part may be called 'one degree' |
Observe the following pictures.

The rise in temperature of the water = _____ .
Water of which container will lose more heat?
A glass of water is taken in a container. Temperature of water is . That water is heated up to with the help of a burner. Then, after making the container empty twenty glasses of water is poured into it. Temperature of water is still . Again the temperature of water is increased to by using the same burner.
In which case will water absorb more heat in going from a temperature of to ?
