1. What temperature is shown below on the thermometer if the temperature is marked in °F?
a) 70 °F
b) 72 °F
c) 74 °F
d) 78 °F
Answer: c) 74 °F
Explanation: The marking is above 70 °F. 1 marking is 2 °F. So, there are 2 markings that are 4 °F. Hence,
Temperature on the thermometer = 70 °F + 4 °F
= 74 °F
2. What is the sum of temperatures in the afternoon and at night if the temperature in the afternoon is 48°C and the temperature at night is 27°C?
a) 65°C
b) 75°C
c) 95°C
d) 105°C
Answer: b) 75°C
Explanation: The sum of temperature in the afternoon and at night = 48 + 27
= 75°C
3. The level of mercury is used to indicate the temperature in degrees Celsius (°C). What is the difference between the marked temperature on a thermometer and the boiling point of water in Celsius?
a) 40 °C
b) 60 °C
c) 80 °C
d) 100 °C
Answer: a) 40 °C
Explanation: Marked temperature on a thermometer = 60 °C
Temperature at which water boils = 100 °C
Difference between the marked temperature on a thermometer and the boiling point of water in Celsius = 100 °C − 60 °C
= 40 °C
4. What is the difference between average temperatures in winter and summer?
a) 75° C
b) 75° F
c) 105° C
d) 105° F
Answer: d) 105° F
Explanation: Temperatures in winter = 35 °F
Temperatures in summer = 140 °F
Difference between temperatures in winter and summer = 140° F - 35° F
= 105° F
5. The thermometer is giving you an incorrect temperature reading. It is showing you a temperature that is 13°C higher than the correct temperature. What is the correct temperature?
a) 53°C
b) 47°C
c) 37°C
d) 27°C
Answer: d) 27°C
Explanation: Incorrect temperature reading = 40°C
The incorrect temperature is 13°C higher than the correct temperature.
Thus, the correct temperature is 13°C lower than the incorrect temperature.
Correct temperature reading = 40°C − 13°C
= 27°C
