Quick Concept Cards

Temperature Basics

🔴 Definition Temperature is the degree of hotness or coldness of a body.

```

🟠 SI Unit The SI unit of temperature is kelvin. Its symbol is K.

🟡 Temperature Scales Common temperature scales are Celsius, Fahrenheit, and Kelvin.

🟢 Measuring Device Temperature is measured using a thermometer.

🔵 Clinical Thermometer It is used for measuring human body temperature.

🟣 Laboratory Thermometer It is used in science experiments and laboratories.

⚫ Scale Relation C/5 = (F − 32)/9 = (K − 273)/5

🌡️ Temperature Scales

Celsius, Fahrenheit, Kelvin

Scale	Symbol	Common Use
Celsius	°C	Daily weather and normal temperature readings
Fahrenheit	°F	Used in some countries for weather and body temperature
Kelvin	K	Scientific measurements

C/5 = (F − 32)/9 = (K − 273)/5

School-level memory trick: Celsius, Fahrenheit, and Kelvin are three different ways to express temperature.

🧪 Types of Thermometers

Comparison

Thermometer	Use	Example
Clinical thermometer	Used to measure human body temperature	Used by doctors during fever check-up
Laboratory thermometer	Used in experiments	Used to measure temperature of water in a beaker
Digital thermometer	Gives quick digital temperature reading	Used at home and hospitals

Daily life example: Doctors use a clinical thermometer to check fever because it is designed for body temperature range.

Quick Check

Normal human body temperature is around 37°C.

37°C ≈ 98.6°F

For school-level Kelvin conversion, K = °C + 273.

🧠 HOTS Questions

Think Deeper

1. Why is Kelvin considered the SI unit?

Kelvin is internationally accepted for scientific temperature measurements.

2. Why should a laboratory thermometer not be used for body temperature?

A laboratory thermometer does not have a constriction and is not specially designed for the human body temperature range.

3. Why does mercury rise on heating?

Mercury expands when heated, so its level rises in the thermometer tube.

4. Why is temperature important in industries?

Many industrial processes require controlled temperature for safety, quality, and proper production.

5. Why is body temperature maintained nearly constant?

A nearly constant body temperature helps body organs function properly.
