Two identical metal spheres at 8 °C are put in equal amount of water in two beakers, as shown below.

eduard

Answer:

$\boxed{ \text{The temperature of the water in Beaker A will increase.}}$

Step-by-step explanation:

Heat always flows from a hotter object to a colder one. If heat flows from the sphere to the water, $\boxed{\textbf {the temperature of the water will increase.}}$

A is wrong. If the temperature of the water is greater than 8 °C, heat will flow from the water to the sphere.

B is wrong. If the temperature of the water is lower than 8 °C, heat will flow from the sphere to the water..

D is wrong. If heat flows from the water to the sphere, the temperature of the water will decrease.
