What this chapter is about
This chapter introduces you to the idea of temperature. Temperature tells us how hot or cold something is. You already know that a glass of lassi from the fridge feels cold, while a cup of tea feels hot. But how do we measure this hotness or coldness? That is what this chapter teaches.
Key ideas
- Temperature is a measure of how hot or cold an object is.
- Our sense of touch can give us a rough idea about temperature, but it is not reliable for exact measurement.
- A thermometer is a device used to measure temperature accurately.
- The unit of temperature we commonly use is degree Celsius, written as °C.
- A clinical thermometer is used to measure body temperature. It usually shows readings from 35 °C to 42 °C.
- A laboratory thermometer is used in science experiments and can measure a wider range of temperatures.
- Normal human body temperature is around 37 °C.
- Heat flows from a hotter object to a colder object until both reach the same temperature.
Formulas and facts to remember
- Temperature: A measure of how hot or cold something is.
- Thermometer: A device that measures temperature.
- Degree Celsius (°C): The common unit for measuring temperature.
- Normal body temperature: About 37 °C.
- Clinical thermometer range: Usually 35 °C to 42 °C.
- Freezing point of water: 0 °C (when water turns to ice).
- Boiling point of water: 100 °C (when water turns to steam).
- Heat always moves from a hotter body to a colder body.
Common mistakes
- Thinking the liquid inside a thermometer is always mercury → Many thermometers now use alcohol or digital sensors.
- Holding the thermometer by the bulb while reading → This warms the bulb and gives a wrong reading.
- Believing our hands can tell exact temperature → Our sense of touch is unreliable; always use a thermometer.
- Forgetting to shake down a clinical thermometer before use → The old reading stays and mixes with the new one.
- Confusing temperature with heat → Temperature tells how hot something is; heat is the energy that flows between objects.
Quick revision
- Temperature measures how hot or cold an object is.
- A thermometer gives us the exact temperature in numbers.
- We measure temperature in degree Celsius (°C).
- Normal human body temperature is about 37 °C.
- Water freezes at 0 °C and boils at 100 °C.
- Our touch can fool us; a thermometer cannot.
