Question

In two beaker (a and b) 50ml water of sbout 70. °c each is taken .then in beaker A , 50 ml of water of about 30 C is added and after 5 minutes, in beaker B, 50 ml of water of about 30 C is added. what would you observe if the temperatures of both beakers recorded immediately

Answer 1

Temperature of water in two beakers will be different.

In beaker  

A : Initially  50ml water of about 70 degree  

B : 50ml water of about 70 degree:Beaker A, 50 ml water at 30 degree added.

So, temperature in this beaker will rise.

Beaker B , after five minutes 50 ml water added at 30 degree.

Now in five minutes temperature of A will fall a bit and temperature of B will rise.

Answer : After five minutes temperature of A will be less than temperature in B.
