Final answer:
To convert 210 K to Celsius, subtract 273.15 from 210 K to get -63.15°C, which rounds to -63.0°C. so, option A is the correct answer.
Step-by-step explanation:
To convert a temperature of 210 K into Celsius degrees, we can use the conversion formula C = K - 273.15, where C is the temperature in Celsius and K is the temperature in Kelvin. Using the formula, we have C = 210 K - 273.15 = -63.15°C. Therefore, the correct answer is a. -63.0°C.
To convert 210 K to Celsius, subtract 273.15 from the temperature in Kelvin: 210 K - 273.15 = -63.15 °C. Rounded to the nearest tenth, this is approximately -63.0 °C.
To convert temperature from Kelvin to Celsius, you need to subtract 273.15 from the temperature in Kelvin.
So, to convert 210 K to Celsius, subtract 273.15:
210 K - 273.15 = -63.15 °C
Rounded to the nearest tenth, this is approximately -63.0 °C (option a).
