Question

if in winter season the surface temperature of lake is 1 Degree Celsius the temperature at the bottom of Lake will be

Answer 1

temperature below the lake must be less than 1 degree celcius

Answer 2

Temperature at the bottom of Lake will be

Either the surface temperature of water is 1°C or less the base layer will have 4°C temperature.It is the temperature at which the water have most extreme density,below or more this temperature the thickness is low.  As the outside of the lake freezes the ice go about as separator and secure the living bodies in water (reference hc verma vol 2) .Typically, the base temperature of a water body is more by 3 degrees than its surface temperature particularly in lakes and stores during winters. On account of a stream, the progression of water is significant. In the event that the base stream is great and with low profundity, the base temperature is probably going to continue as before . In freshwater, the most elevated thickness of water is at around 3 to 4 degree centigrade.
