Question

The value of –10 ºC temperature in Kelvin scale is

• A. 283 K
• B. 263 K
• C. 273 K
• D. 0 K

Hint:

Formula: To convert Celsius to Kelvin, use the formula:

Kelvin = Celsius + 273

Given temperature: –10 ºC 

Applying the formula:

Kelvin = –10 + 273 = 263 K

Final Answer: 263 K

Answer 1

The Correct Option is B

The Kelvin scale is an absolute temperature scale used in physics and chemistry. 
To convert a temperature from Celsius to Kelvin, the following equation is used: K = °C + 273.15.

For this problem, we need to convert –10 ºC to Kelvin. 
Applying the conversion formula gives:

K = –10 + 273.15 = 263.15 K

Since temperature values in Kelvin are typically expressed as whole numbers when dealing with typical temperature ranges, we can round 263.15 K to 263 K. 

Therefore, the value of –10 ºC in Kelvin is 263 K.
