**Converting 293 K to Celsius**

To convert a temperature from Kelvin to Celsius, we need to subtract 273.15 from the given temperature in Kelvin. Let's follow the steps below to convert 293 K to Celsius.

**Step 1: Understand the Kelvin Scale**

Before we proceed with the conversion, it is important to understand the Kelvin scale. Kelvin is an absolute temperature scale where 0 K represents the lowest possible temperature, known as absolute zero. In this scale, temperatures are measured in Kelvin (K) rather than degrees Celsius (°C).

**Step 2: Subtract 273.15 from the Given Temperature**

To convert 293 K to Celsius, we subtract 273.15 from the given temperature:
293 K - 273.15 = 19.85 °C

**Step 3: Interpretation**

The result of the conversion is 19.85 °C. This means that a temperature of 293 K is equivalent to 19.85 °C on the Celsius scale.

**Explanation**

The Kelvin scale is based on the concept of absolute zero, where molecules have minimum possible kinetic energy. The Celsius scale, on the other hand, is based on the freezing and boiling points of water.

To convert from Kelvin to Celsius, we need to consider the fact that 0 K is equal to -273.15 °C. This is because the Celsius scale sets the freezing point of water at 0 °C and the boiling point of water at 100 °C.

Therefore, to convert any temperature from Kelvin to Celsius, we subtract 273.15 from the given temperature. In this case, we subtract 273.15 from 293 K, resulting in 19.85 °C.

It's important to note that the Celsius scale is commonly used for everyday temperature measurements, while the Kelvin scale is frequently used in scientific calculations and in the study of thermodynamics.

Celsius = Kelvin -273 = 293-273=20 C
