Important Questions on Temperature and Its Measurement

EASY
Differentiate clinical thermometer and laboratory thermometer.
MEDIUM
Explain the working of ethanol thermometer.
EASY
Where is a ethanol thermometer used for ?
EASY
Ethanol thermometer is not suitable to measure low temperatures.
EASY
A thermistor is a specific type of resistor that uses sensors to help regulate cold and heat.
EASY
Alcohol thermometers are used to measure low temperature.
EASY
Name the thermometer which does not use mercury as the thermometric liquid.
EASY
An ethanol thermometer has a greater value of _____ coefficient of expansion than a mercury thermometer.
EASY
In the first thermometer air was used as the thermometric substance.
EASY
A clinical thermometer contains a thermistor.
MEDIUM
List the advantages of ethanol thermometer over other liquid thermometers.
EASY
The first thermometer was invented by Galileo.
MEDIUM
Air was used in the first thermometer as it expands rapidly on _____ and contracts on cooling.
EASY
What are the uses of thermistor thermometer?
EASY
Thermistors are used as thermal sensors.
EASY
Mercury or _____ (water/alcohol) is used in thermometer.
EASY

The resistance of a thermistor at 0°C is 2000 Ω. At 100 °C the resistance falls to 200 Ω. When the thermistor is placed in water of constant temperature, its resistance is 620 Ω.

Assuming that the resistance of the thermistor varies linearly with temperature, calculate the temperature of the water.
