Question

A solid object heated to 120°C is placed inside a container of water at 33°C. A thermometer is placed inside the container and a measurement of the temperature is taken every few seconds. Which graph BEST represents the change in water temperature after the solid object is added?

Answer 1

c

Step-by-step explanation:

Answer 2

Since the object that was added into the water was hot, the water's temperature will increase. The increase of temperature with time will follow a curve increasing from 33°C towards the equilibrium temperature. The curve will plateau when it reaches the equilibrium temperature.
