FAQ: Converting 120°C to Kelvin
What is 120°C in Kelvin?
To convert Celsius to Kelvin, you add 273.15 to the Celsius temperature. Therefore, 120°C is equal to 393.15 K.
How do you convert Celsius to Kelvin?
The formula to convert Celsius to Kelvin is:
[ K = °C + 273.15 ]
So, for 120°C:
[ 120 + 273.15 = 393.15 \text{ K} ]
Why do we add 273.15 to Celsius to get Kelvin?
The Kelvin scale is an absolute temperature scale starting at absolute zero, the point where all molecular motion stops. The Celsius scale is based on the freezing and boiling points of water. The difference between the freezing point of water (0°C) and absolute zero is 273.15 degrees, hence the addition of 273.15.
Is Kelvin used more often than Celsius?
Kelvin is primarily used in scientific contexts, especially in physics and chemistry, because it is an absolute scale. Celsius is more commonly used in everyday life and in weather reporting.
Can you convert Kelvin back to Celsius?
Yes, you can convert Kelvin back to Celsius by subtracting 273.15 from the Kelvin temperature. For example, to convert 393.15 K back to Celsius:
[ 393.15 – 273.15 = 120°C ]
What is the significance of the Kelvin scale?
The Kelvin scale is significant because it starts at absolute zero, the theoretical lowest possible temperature where molecular motion ceases. This makes it very useful for scientific calculations and understanding thermodynamic principles.
Is 120°C a high temperature?
Yes, 120°C is considered a high temperature. It is well above the boiling point of water (100°C) and is often used in industrial processes and scientific experiments.
What are some practical applications of converting Celsius to Kelvin?
Converting Celsius to Kelvin is essential in scientific research, particularly in fields like thermodynamics, chemistry, and physics. It allows scientists to perform calculations involving absolute temperatures, which are crucial for understanding energy transformations and reactions.
How does the Kelvin scale differ from the Celsius scale?
The Kelvin scale is an absolute temperature scale with its zero point at absolute zero (-273.15°C), where all molecular motion stops. The Celsius scale, on the other hand, is a relative scale based on the freezing (0°C) and boiling points (100°C) of water at standard atmospheric pressure.
What is absolute zero in Celsius?
Absolute zero is the lowest possible temperature where molecular motion stops. In Celsius, absolute zero is -273.15°C.
Why is the Kelvin scale important in scientific research?
The Kelvin scale is important because it provides an absolute reference point for temperature measurements, which is essential for accurate scientific calculations. It helps in understanding the fundamental principles of thermodynamics and the behavior of gases, liquids, and solids
