Math in Focus Grade 3 Chapter 16 Practice 6 Answer Key Measuring Temperature
Fill in the blanks with these words.
Question 1.
Answer:
1. Room temperature: The temperature maintained thermostatically that encompasses at the usual and customary working environment of 20°-25° (68°-77 °F).
2. The temperature feels like 32°F to 50°F then it is cold.
3. The temperature feels like 50° F to 68°F then it is cool.
4. The temperature feels like 104° F to 122° then it is very hot.
5. The simple answer to this question is that the boiling point of water is100 °C or 212 °F at 1 atmosphere of pressure (sea level). However, the value is not a constant. The boiling point of water depends on the atmospheric pressure, which changes according to elevation.
Write each temperature using °F. Then write hot, warm, cool, or cold to describe the temperature.
Example
Question 2.
Answer: 71°F; warm.
Explanation: If the temperature feels 68°-77 °F then it comes under warm or it is at room temperature.
Question 3.
Answer: 125°F; Very hot.
Explanation:
-A temperature higher than 89°C or 192°F is considered very hot.
Question 4.
Answer: 94°F; Hot.
Explanation:
-A temperature higher than 75°C or 167°F is considered hot.
Question 5.
Answer:85°F; warm
Explanation:
– serving to maintain or preserve heat especially to a satisfactory degree a warm sweater.
– If the temperature feels 68°-77 °F then it comes under warm or it is at room temperature.
Question 6.
Answer: 101°F; hot.
Explanation:
-A temperature higher than 75°C or 167°F is considered hot.
Question 7.
Answer:21°F; very cold.
– The definition of cold is: “Of or at a low or relatively low temperature, especially when compared with the human body.” If you want to get technical, the temperature at which water freezes is 32 degrees Fahrenheit. The freezing temperature is also 0 degrees Celsius and 273.15 Kelvin.
– The temperature feels like below 32 degrees Fahrenheit then it comes under very cold.
Circle the temperature that matches the activity.
Question 8.
18°F
70°F
Answer: 70°F; warm.
Explanation:
– In the picture, he was reading and sitting in a very relaxed position. Then definitely it is room temperature. If the temperature feels like 68°F to 86°F then it is warm where the human body can control the temperature and feel free.
Question 9.
98°F
102°F
Answer:
Explanation:
– In the picture, a person is sick and the temperature is reading with thermometer. So, the temperature is above 100 degrees then it is hot. So I prefer 102 degrees Fahrenheit.
Circle the picture that matches the temperature.
Question 10.
Answer: It is freezing.
The freezing point of water is zero degrees Centigrade or 32 degrees Fahrenheit. Rather, we can say that zero degrees are the point at which water is melting at the same rate it is freezing. Hence, creating a balance. Actually, at zero-degree water molecules are moving very slowly, and the formation of solid begins i.e. Ice.
Question 11.
Answer:100 degrees Fahrenheit.
Explanation:
-A temperature higher than 75°C or 167°F is considered hot.
Shade the temperature on each thermometer.
Example
65°F
Question 12.
50°F
Answer: 50°F; cool.
- Cool: Any temperature between 8° and 15° (46° and 59 °F)
Question 13.
32°F
Answer: 32°F, very cold.
– The definition of cold is: “Of or at a low or relatively low temperature, especially when compared with the human body.” If you want to get technical, the temperature at which water freezes is 32 degrees Fahrenheit. The freezing temperature is also 0 degrees Celsius and 273.15 Kelvin.
– The temperature feels like below 32 degrees Fahrenheit then it comes under very cold.
Question 14.
212°F
Answer: 212°F; boiling point
The boiling point of water is 100 degrees Celsius or 212 degrees Fahrenheit at 1 atmosphere of pressure, or sea level. The boiling point of water depends on the atmospheric pressure, which changes according to elevation.
Question 15.
0°F
Answer:0°F; very cold
– The definition of cold is: “Of or at a low or relatively low temperature, especially when compared with the human body.” If you want to get technical, the temperature at which water freezes is 32 degrees Fahrenheit. The freezing temperature is also 0 degrees Celsius and 273.15 Kelvin.
– The temperature feels like below 32 degrees Fahrenheit then it comes under very cold.

Question 16.
Water boils at __________°F.
Answer: 212 °F.
The boiling point of water is 100 degrees Celsius or 212 degrees Fahrenheit at 1 atmosphere of pressure, or sea level. The boiling point of water depends on the atmospheric pressure, which changes according to elevation.
Question 17.
Water freezes at ___________°F.
Answer:32 °F
The optimal temperature in cold conditions is 0°C 0r 32 °F. However, if the chamber is left open for a while or hot food is added, the equilibrium will be disturbed and the cubes will harden more slowly.
