Two identical metal spheres at 8 °C are put in two beakers with equal amounts of water, as shown below.
Two beakers are side by side; one is labeled Beaker A and the other is labeled Beaker B. Both beakers are the same shape, size, and are about two-thirds full with water. Both beakers have a metal sphere with a temperature of eight degrees Celsius submerged in the water.
Heat flows from the water to the metal spheres in Beaker A and Beaker B. Which statement is correct?
The temperature of the water in both beakers is lower than 8 °C.
The temperature of the water in both beakers is greater than 8 °C.
The temperature of the water in both beakers will increase.
The temperature of the metal spheres in both beakers will decrease.

If heat flows from the water to the spheres and you know that heat flows from higher temperature to the lower temperature then you know that the T of the water must higher than the T of the sphere @ 8 C SO T of the beakers will decrease since they losing heat and T of the spheres will increase since they are gaining heat.
