Mini tried to cool her tea by blowing on it. Which of the following do...
Answer:
Introduction
In this question, we are asked to determine which of the given options will be hotter when Mini tries to cool her tea by blowing on it. Let's analyze each option to understand the correct answer.
Analysis of Options
a) Mini's tea
When Mini blows on her tea, the air from her mouth comes into contact with the hot tea. The heat from the tea transfers to the air molecules, causing them to move faster and therefore increasing their temperature. As a result, the tea will become slightly hotter.
b) The air she blew from her mouth
As Mini blows on her tea, the air from her mouth is in direct contact with the hot tea. Since the tea is hotter than the air from her mouth, the heat will transfer from the tea to the air molecules. This transfer of heat will cause the air blown from her mouth to become hotter.
c) The atmospheric air
The atmospheric air refers to the air surrounding us, which is generally at room temperature. When Mini blows on her tea, the hot air from her mouth will mix with the cooler atmospheric air. The heat from the hot air will transfer to the cooler air, causing it to become slightly warmer. However, since the atmospheric air is at a lower temperature than the tea, it will not become hotter than the tea.
d) None of these
Since we have determined that both Mini's tea and the air she blew from her mouth will become hotter, we can conclude that the correct answer is not "None of these."
Conclusion
Based on the analysis above, we can conclude that Mini's tea (option a) will be hotter when she tries to cool it by blowing on it. The heat from the tea will transfer to the air blown from her mouth, but the atmospheric air will not become hotter than the tea.
