To convert Kelvin to Celsius, you can use the following formula:

Celsius = Kelvin – 273.15

So, in this case, 298.15 Kelvin to Celsius would be:

Celsius = 298.15 – 273.15

Celsius = 25°C

Kelvin is a unit of temperature in the International System of Units (SI) and is based on the triple point of water, which is defined as 273.16 K. This means that 0 K is absolute zero, the lowest possible temperature. On the other hand, Celsius is based on the freezing and boiling points of water, with 0°C being the freezing point and 100°C being the boiling point at standard atmospheric pressure.

Converting between Kelvin and Celsius is important in scientific research and many fields like physics, chemistry, and engineering. For example, in physics, Kelvin is often used for thermodynamic calculations and in chemistry, it is used to measure absolute temperatures in chemical reactions.

Understanding temperature conversions is crucial for many scientific experiments and analyses. Teaching students to convert temperatures from one unit to another helps them develop a deeper understanding of the principles behind these units and their use in real-world applications. By explaining the relationship between Kelvin and Celsius, students can gain a better understanding of temperature scales and how they are used in scientific research and everyday life.

In conclusion, 298.15 Kelvin is equivalent to 25°C. Understanding the conversion between Kelvin and Celsius is important for many scientific disciplines and can provide valuable insights into the principles of temperature measurement and its applications in the real world.
