Understanding What Temperature Is
Temperature is a measure of how hot or cold something is. It tells us how fast the tiny particles inside an object or substance are moving.
How Temperature Works
When particles move quickly, the temperature is high. When they move slowly, the temperature is low. Temperature reflects this motion and energy.
Why Temperature Matters
Temperature affects weather, cooking, health, and how materials behave. It helps us understand heat, energy, and the conditions around us.
Common Temperature Scales
The most used scales are Celsius (°C), Fahrenheit (°F), and Kelvin (K). Scientists often use Kelvin because it starts at absolute zero, the lowest possible temperature.
Temperature in Daily Life
We use temperature to check the weather, cook food, measure body heat, and maintain machines or devices. It influences almost everything we do.
The Simple Takeaway
Temperature measures how fast particles are moving. It helps explain heat, cold, and the physical changes we see in the world.
