FAQs on Temperature and its Measurement Video Lecture - Science for Class 6

1. What is temperature and why is it important?
Ans.Temperature is a measure of how hot or cold something is. It is important because it affects our daily lives, such as how we dress, how food is cooked, and even our health. Understanding temperature helps us to adapt to different weather conditions and manage our environment.
2. How do we measure temperature?
Ans.Temperature is measured using different instruments called thermometers. Common types include mercury thermometers, digital thermometers, and alcohol thermometers. Each type has a scale, usually in Celsius (°C) or Fahrenheit (°F), to show the temperature reading.
3. What are the different scales of temperature measurement?
Ans.The most common scales for measuring temperature are Celsius (°C), Fahrenheit (°F), and Kelvin (K). Celsius is widely used in most countries, Fahrenheit is primarily used in the United States, and Kelvin is mainly used in scientific contexts.
4. What is the freezing and boiling point of water in Celsius and Fahrenheit?
Ans.In Celsius, the freezing point of water is 0°C and the boiling point is 100°C. In Fahrenheit, the freezing point is 32°F and the boiling point is 212°F. These points are important reference points for understanding temperature changes.
5. Why do we use a thermometer instead of our hands to measure temperature?
Ans.We use a thermometer because it provides an accurate and precise measurement of temperature, while our hands can only give a rough estimate of how hot or cold something feels. Thermometers are designed to measure temperature changes accurately, ensuring reliable results.
