4/20
What two types of thermometers are commonly used?
4/20
The two common types of thermometers are clinical thermometers (for measuring body temperature) and laboratory thermometers (for various scientific purposes).
5/20
How does a clinical thermometer work?
5/20
A clinical thermometer works by measuring temperature when in contact with a person's body, often displaying readings digitally.
6/20
What is the normal body temperature?
6/20
The normal body temperature for a healthy human is approximately 37.0 °C, though it may vary slightly among individuals.
7/20
What precautions should be taken when using a digital thermometer?
7/20
Wash the tip with soap and water before and after use and avoid immersion of the digital display in water.
8/20
What scale is used in clinical thermometers?
8/20
Clinical thermometers generally use the Celsius scale to display body temperature in degrees Celsius (°C).
9/20
What is an infrared thermometer?
9/20
An infrared thermometer is a non-contact thermometer that measures temperature without physical contact, useful for reducing the risk of disease transmission.
10/20
How do you read a laboratory thermometer?
10/20
A laboratory thermometer should be read while it is immersed in the liquid, and your eye should be aligned with the liquid level in the tube.
11/20
What is the range of a typical laboratory thermometer?
11/20
A typical laboratory thermometer might have a range from -10 °C to 110 °C.
12/20
How do factors influence body temperature?
12/20
Body temperature can be influenced by age, activity level, and the time of day, leading to variations from the average normal.
13/20
What is the Fahrenheit scale?
13/20
The Fahrenheit scale is another temperature scale with units measured in degrees Fahrenheit (°F), where 37.0 °C equals 98.6 °F.
14/20
What is the Kelvin scale?
14/20
The Kelvin scale is the SI unit of temperature, denoted by K, used primarily in scientific contexts.
15/20
How to convert Celsius to Kelvin?
15/20
To convert Celsius to Kelvin, use the formula: Temperature in Kelvin = Temperature in Celsius + 273.15.
16/20
What happens to the temperature of boiling water?
16/20
The temperature of boiling water remains constant at 100 °C at sea level, despite continuous boiling.
17/20
What are some common mistakes when measuring temperature?
17/20
Common mistakes include not waiting for the thermometer to stabilize, not reading at eye level, and holding the thermometer incorrectly.
18/20
How can temperature be measured in air?
18/20
Air temperature is measured using outdoor thermometers that provide readings of maximum and minimum temperatures over time.
19/20
Who was Anna Mani?
19/20
Anna Mani was an Indian scientist known for her contributions to meteorology and for inventing weather measurement instruments.
20/20
What impact does the environment have on temperature readings?
20/20
Environmental changes, such as weather patterns, can cause daily temperature variations that are tracked by meteorological stations.
