Celsius to Kelvin Conversions

The video tutorial teaches students how to convert temperatures from Celsius to Kelvin using a simple formula: Kelvin = Celsius + 273. The instructor provides two examples: converting 20°C and 4.2°C to Kelvin. The importance of using significant figures in reporting the final answer is also discussed. By the end of the lesson, students should be able to perform these conversions independently.
