🌡️ Class 7 Science — Temperature and Its Measurement (MCQs with Answers)

Temperature tells us how hot or cold a substance is — it’s something we feel every day, from a hot cup of tea to a cool breeze. In Class 7 Science, the topic “Temperature and Its Measurement” helps students understand what temperature means, how it’s measured, and why it’s important in daily life.

There are three main temperature scales — Celsius (°C), Fahrenheit (°F), and Kelvin (K). The SI unit of temperature is Kelvin (K). A clinical thermometer is used by doctors to check body temperature, while a laboratory thermometer is used for scientific experiments. The normal body temperature of a healthy person is 37 °C or 98.6 °F, and a laboratory thermometer usually measures from –10 °C to 110 °C.
