The number 273 is an integer that follows 272 and precedes 274. It is an odd number and can be expressed as the sum of two prime numbers: 271 and 2. In mathematics, it is often used in various calculations and can be found in different contexts, such as statistics and number theory. In the context of temperature, 273 Kelvin is equivalent to 0 degrees Celsius, which is the freezing point of water. This relationship is significant in science, particularly in fields like thermodynamics and meteorology, where temperature measurements are crucial for understanding physical processes.
