Match the following. | Column A | Column B | |---|---| | 1. Digital thermometer | a. Radiation | | 2. Laboratory thermometer | b. An insulator | | 3. 0°C | c. Range from -10°C to 110°C | | 4. Wool | d. Freezing point of water | | 5. Black base of cooking utensils | e. Thermistor |
Answer (1)
To match the items in Column A with those in Column B, let's look at each item one by one:
Digital thermometer : This device typically uses a sensor called a thermistor to measure temperature. Therefore, the match is with option e. Thermistor.
Laboratory thermometer : These thermometers are designed for measuring temperatures in scientific experiments and can typically measure a range from -10°C to 110°C. Hence, the match is option c. Range from -10°C to 110°C.
0°C : This is known as the freezing point of water. Thus, the match is option d. Freezing point of water.
Wool : Wool is a material that is commonly used as an insulator because it traps air and keeps heat in. Therefore, it matches with option b. An insulator.
Black base of cooking utensils : Black surfaces are known to absorb radiation better, which makes them efficient in absorbing heat. Thus, the match is option a. Radiation.
In summary:
Digital thermometer - e. Thermistor
Laboratory thermometer - c. Range from -10°C to 110°C
0°C - d. Freezing point of water
Wool - b. An insulator
Black base of cooking utensils - a. Radiation
