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. $15^\circ\text{C}$
