Three identical beakers have 80ml of water, 50ml of water and 50ml of ice. The water in the first 2 beakers is initially at the same temperature. If all three beakers are heated in a similar way for one minute, in which beaker will the rise of temperature be highest?

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.
Answer: the 50ml of water
Explanation: theres less space to heat up and less energy to heat up than a cup of ice water of an 80ml of water
