Here are the correct answers for the temperature worksheet, based on common real-world temperatures and the difference between Fahrenheit (°F) and Celsius (°C).

1. The temperature of a typical summer day is
* Reasoning: $30^\circ\text{C}$ is equal to $86^\circ\text{F}$, which is a warm summer day. $15^\circ\text{C}$ ($59^\circ\text{F}$) is cool, and $-5^\circ\text{F}$ is freezing cold.
* Answer: a. $30^\circ\text{C}$

2. The temperature of a snowy day should be below
* Reasoning: Snow forms when it is freezing or colder. Freezing is $0^\circ\text{C}$ or $32^\circ\text{F}$. Therefore, the temperature must be below $32^\circ\text{F}$.
* Answer: c. $32^\circ\text{F}$

3. The water in a hot bubble bath should NOT be lower than
* Reasoning: A comfortable hot bath is usually around body temperature or slightly higher ($37^\circ\text{C}$ - $40^\circ\text{C}$). $37^\circ\text{C}$ is normal body temperature. $98^\circ\text{F}$ is also body temperature, but $98^\circ\text{C}$ is boiling hot and would burn you! $40^\circ\text{F}$ is refrigerator cold. Between the safe options, $37^\circ\text{C}$ is the standard reference for warm/hot water relative to the body.
* Answer: a. $37^\circ\text{C}$

4. The soup served in a restaurant should be around
* Reasoning: Hot soup is served near boiling point but safe to eat. $100^\circ\text{C}$ is the boiling point of water. $100^\circ\text{F}$ is just hot tap water (lukewarm for soup). $50^\circ\text{F}$ is cold.
* Answer: a. $100^\circ\text{C}$

5. The temperature of boiling water is
* Reasoning: Water boils at $100$ degrees Celsius. In Fahrenheit, it boils at $212$ degrees.
* Answer: b. $100^\circ\text{C}$

6. If your body temperature is at \_\_\_\_\_ you are having a fever.
* Reasoning: Normal body temperature is about $37^\circ\text{C}$ ($98.6^\circ\text{F}$). A fever is anything significantly higher than that. $103^\circ\text{F}$ is a high fever. $10^\circ\text{C}$ and $23^\circ\text{C}$ are dangerously low (hypothermia).
* Answer: c. $103^\circ\text{F}$

7. The water turns to ice when the temperature is lower than
* Reasoning: The freezing point of water is $0^\circ\text{C}$ or $32^\circ\text{F}$. Ice forms when it gets colder than this point.
* Answer: b. $0^\circ\text{C}$

8. It is nice and dry in the fall when the temperature is around
* Reasoning: Fall (autumn) is cool but not freezing. $15^\circ\text{C}$ is about $59^\circ\text{F}$, which is perfect crisp fall weather. $15^\circ\text{F}$ is very cold winter weather. $20^\circ\text{F}$ is also below freezing.
* Answer: a. $15^\circ\text{C}$

Final Answer:
1. a
2. c
3. a
4. a
5. b
6. c
7. b
8. a
