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.
