When two samples at different temperatures are mixed, the temperature of mixture can be

i) equal to lower or higher temperature

ii) greater than lower but less than higher temperature

iii) average of lower and higher temperatures

When two samples at different temperatures are mixed, the temperature of

mixture can be

(i)equal to lower or higher temperature.

Ex : when ice cubes are mixed with water at room temperature then water

also cool down to $0°\text{C}$

Ex : When water at room temperature is heated by steam at $100°\text{C}$then

water also raises its temperature to $100°\text{C}$

(ii)greater than the lower temperature but less than higher tempeture

(iii) Average of lower and higher temperatures.

We get all (i), (ii) and (iii) as true by using daily life illustrations.
