8. One litre of water at 30°C is mixed with one litre of water at 50°C. The temperature of the mixture will be
(a) 80°C
(b) more than 50°C but less than 80°C
(c) 20°C
(d) between 30°C and 50°C
If one litre of water is mixed with one litre of water at . Then, the temperature of the mixture will be
(d) between and
Because the volume of both the liquids with temperature is equal. Therefore, when we add both theories, there is a transfer of heat that takes place from a liquid with a high temperature to a liquid with a low temperature. That's why the temperature is between and
