Question

the plastic sphere is placed in 500 mL of water. The plastic sphere’s temperature is 85 °C. The water’s temperature is 15 °C. In wich direction will the thermal energy move, from the plastic to the water or the water to the plastic. Explain your answer

Answer 1

Heat energy will flow from the plastic sphere to the water. This is because heat energy always flows from a warmer object to a cooler object.

Step-by-step explanation:

In this case, the plastic sphere has a higher temperature of 85 °C, while the water has a lower temperature of 15 °C. Therefore, heat energy will naturally flow from the plastic sphere to the water until both objects reach thermal equilibrium, where they have the same temperature. As a result, the plastic sphere will cool down and the water will warm up until they reach the same temperature.
