23: Heat and Temperature
- #10The temperature of water at the surface of a deep lake is 2°C. The temperature expected at the bottom is
(a) 0 °C
(b) 2 °C
(c) 4 °C
(d) 6 °CdigAnsr: cAns : (c) 4 oC
The density of water is maximum at 4 oC, and the water at the bottom of the lake is most dense, compared to the layers of water above. Therefore, the temperature expected at the bottom is 4oC.
