To convert temperature from Kelvin (K) to Fahrenheit (°F), we first convert Kelvin to Celsius (°C) and then Celsius to Fahrenheit. The formula for converting Kelvin to Celsius is: °C = K - 273.15 Given temperature is 273 K. °C = 273 - 273.15 = -0.15 °C. However, in many contexts, 273 K is treated as approximately 0°C, especially in simplified problems like this. Let's use 0°C.The formula for converting Celsius to Fahrenheit is: °F = (°C × 9/5) + 32 Using °C = 0: °F = (0 × 9/5) + 32 °F = 0 + 32 °F = 32.So, 273 K is equivalent to 32°F. This corresponds to the freezing point of water.
If a scientist reads an ambient temperature 273 K in the laboratory, what will a doctor's thermometer read it ?
