Question

What information do we need to convert the temperature in K to °C? (Select all that apply.)

a) the given temperature in K

b) the conversion between Kelvin and °C

c) the conversion between °F and °C

d) the equivalence statement, 1 mL = 1 cm³

Answer 1

To convert temperature from Kelvin to Celsius, subtract 273.15 from the Kelvin value. The only information needed is the Kelvin temperature and the conversion formula, which is T°C = TK - 273.15.

Step-by-step explanation:

To convert the temperature in Kelvin (K) to degrees Celsius (°C), we need the following information:

• The given temperature in Kelvin (a).
• The conversion formula between Kelvin and °C (b), which is T°C = TK - 273.15.

You do not need the conversion between °F and °C (c) for this task, nor do you need the equivalence statement that 1 mL equals 1 cm³ (d).

Using the correct conversion formula, you simply subtract 273.15 from the Kelvin temperature to get the temperature in °C.
