Convert $4.22 \, K$ To $^{\circ}C$.A. $-156.89^{\circ}C$ B. $-356.51^{\circ}C$ C. $-268.93^{\circ}C$

Understanding the Kelvin Scale

The Kelvin scale is a temperature scale that is used in scientific and engineering applications. It is defined such that 0 K is absolute zero, the theoretical temperature at which all matter would have zero entropy. The Kelvin scale is an absolute temperature scale, meaning that it is not relative to a reference point like the Celsius or Fahrenheit scales.

Converting Kelvin to Celsius

To convert a temperature from Kelvin to Celsius, we can use the following formula:

°C = K - 273.15

Where K is the temperature in Kelvin and °C is the temperature in Celsius.

Example Problem: Converting $4.22 \, K$ to $^{\circ}C$

Let's use the formula above to convert $4.22 \, K$ to $^{\circ}C$.

°C = K - 273.15 °C = 4.22 - 273.15 °C = -268.93

Therefore, $4.22 \, K$ is equivalent to $-268.93^{\circ}C$.

Answer Options

A. $-156.89^{\circ}C$ B. $-356.51^{\circ}C$ C. $-268.93^{\circ}C$

The correct answer is C. $-268.93^{\circ}C$.

Q: What is the Kelvin scale?

A: The Kelvin scale is a temperature scale that is used in scientific and engineering applications. It is defined such that 0 K is absolute zero, the theoretical temperature at which all matter would have zero entropy.

Q: How is the Kelvin scale different from the Celsius scale?

A: The Kelvin scale is an absolute temperature scale, meaning that it is not relative to a reference point like the Celsius or Fahrenheit scales. This means that 0 K is the absolute zero point, whereas 0 °C is the freezing point of water.

Q: What is the formula to convert Kelvin to Celsius?

A: The formula to convert Kelvin to Celsius is °C = K - 273.15, where K is the temperature in Kelvin and °C is the temperature in Celsius.

Q: Can you give an example of how to use the formula?

A: Let's say we want to convert 300 K to Celsius. Using the formula, we get:

°C = K - 273.15 °C = 300 - 273.15 °C = 26.85

Therefore, 300 K is equivalent to 26.85 °C.
