What is Temperature?

Temperature is a measure of how hot or cold something is. It helps us understand if something is hot or freezing. We use a special device called a thermometer to measure temperature. The thermometer usually has a scale with degrees and a liquid inside that expands or contracts according to the temperature.

Origin of Temperature

The concept of temperature has been studied for a very long time. The ancient Greeks and Egyptians were some of the first civilizations to explore the idea of temperature. However, it wasn’t until the 16th and 17th centuries that scientists like Isaac Newton and Galileo Galilei began to develop temperature scales and instruments to measure it accurately.

Temperature in Everyday Life

We experience temperature every day. When we go outside on a sunny day, we can feel the warmth of the sun on our skin. When we drink a hot cup of cocoa, we can feel the heat in our mouths. Similarly, in winter, we wear warm clothes to protect ourselves from the freezing temperatures.

Synonyms and Comparison

Temperature is often used interchangeably with the words “heat” or “cold.” Heat refers to high temperatures, while cold refers to low temperatures. It’s like when you touch a hot stove, you feel the heat; and when you touch an ice cube, you feel the cold.

Temperature can also be compared to a weather forecast. Just like a weather forecast tells us if it’s going to be hot or cold outside, temperature helps us understand the hotness or coldness of objects.


In conclusion, temperature is a way to measure how hot or cold something is. It’s a concept that has been studied for centuries and helps us understand our everyday experiences with heat and cold. So, the next time you feel the warmth of the sun or the chilliness of an ice cream, remember that it’s all about temperature!
