what is the SI unit of mass? temperature?time?
Answer (1)
1. Mass – kilogram (kg)Example:You're at the market buying rice. You ask for 5 kilograms of rice because that’s what your family usually consumes in a week. The vendor weighs it on the scale using kilograms, the standard unit for mass.2. Temperature – kelvin (K)Example:While scientists usually use kelvin in labs, you experience temperature in Celsius every day. For example, when it’s 25°C outside (warm day), that’s actually 298 kelvin in scientific terms. Meteorologists and researchers use kelvin when studying weather or climate.3. Time – second (s)Example:When you boil an egg, you might set a timer for 300 seconds, which is 5 minutes. Every second matters in cooking—especially if you want a soft- or hard-boiled egg. That countdown is measured in seconds, the SI unit of time
