Temperature and its Measurement Class 6 Long Question Answer

Question 1.

Describe how a thermometer works to measure temperature. Include the role of the liquid inside the thermometer and how it changes with temperature.

Answer:

A thermometer measures temperature using a liquid, usually mercury or alcohol, contained in a very thin glass tube. When the temperature increases, the liquid inside the thermometer expands and rises up the tube. When the temperature decreases, the liquid contracts and falls. The scale on the thermometer allows us to read the temperature based on how high or low the liquid level is.

Question 2.

What are the main influences of temperature in nature?

Answer:

A wide variety of physical processes are connected to temperature. Such physical properties of bodies include density, vapour pressure, solubility, electrical conductivity, thermal conductivity, state of matter, strength, etc. Other related phenomena are :

1. The range and the rate at which chemical reactions happen.
2. The air temperature directly affects almost every organism.

Question 3.

What are some common applications of thermometers in various fields?

Answer:

Thermometers are used in various fields, including medicine for monitoring body temperature, cooking for ensuring food safety, meteorology for weather forecasting, and industrial processes for quality control. They are also essential in scientific research for experiments requiring precise temperature measurements, highlighting their versatility and importance.
