Question

In two beakers (A& B) 50ml water of abt 70 degree Celsius each is taken. Then in beaker A , 50ml of water of abt 50 degree Celsius is added and 5 mins, in beaker B ,50 ml of water of abt 30 degree Celsius is added. What would observe if the temperature of both beakers recorded immediately? Why?

Answer 1

Beaker B would be more warmer than beaker A  

Reason:

As we know that heat transfers from higher temperature to lesser temperature.

For Beaker A,  

As we pour 30°C water in 70°C water, the temperature contrast is enormous so water will cool instantly and for five minutes it'll cool against distinction with room temperature.  

For Beaker B,  

After waiting for 5 minutes with 70°C water in room, so that will cool it gradually. Additionally after 5 minutes we will add 30°C water to it, however temperature distinction will be little so cooling will be truly moderate.  

In this manner on the off chance that we measure temperature quickly following 5 minutes, beaker B will be more warmer than  A.

Hope this helps!
