Answer:
As the ball is at 70 degree celsius and the water is at 30 degree celsius, the heat flow will take place from the hot metal ball towards the water which is at low temperature. Therefore, there will be a decrease in the temperature of the metal ball.

Answer:
Explanation:
Since there is a difference in temperature between the water and ball, and heat always flows from the body at high temperature to the body at low temperature therefore heat will flow from ball to water. The heat flow continues till both the bodies reach the equilibrium temperature. In this case it will be 50°C.
