Imani's Experiment with Sencha Tea and Silver Spoon
What energy change occurs when the silver spoon is added to the hot cup of sencha tea?
A. The spoon adds its cold to the hot tea
B. The hot tea absorbs the heat from the spoon
C. The cool spoon causes the water to expand thus cooling it
D. The tea loses heat to the spoon causing the spoon to become warmer
Answer:
D. The tea loses heat to the spoon causing the spoon to become warmer
When the silver spoon at a lower temperature than the tea is added to the tea, a heat transfer occurs between the two until equilibrium is reached. Heat transfer takes place from the body with a higher temperature to a body with a lower temperature. As a result, the tea loses heat to the spoon causing the spoon to become warmer.
During the experiment, the thermal energy from the hot tea is transferred to the cooler silver spoon, leading to an increase in the spoon's temperature. This transfer of heat results in a change in the energy of both the tea and the spoon.
In conclusion, the energy change that occurs when the silver spoon is added to the hot cup of sencha tea is that the tea loses heat to the spoon, causing the spoon to become warmer.
