-255 K
0 K
18 K
291 K

Answers

Answer 1

Answer: So, when converting Celsius to Kelvin, this could be a very tricky step. When converting it to Kelvin, we would most likely known that the number would be very big, not to big, but in the hundreds. And as for this, your answer would be 291.15

Answer 2

Answer:

Final answer:

To convert a temperature from Celsius to Kelvin, you need to add 273.15 to the Celsius temperature. In the case of 18°C, this results in 291.15 K. As Kelvin values are often rounded, the answer is 291 K.

Explanation:

The question asks for the conversion of a temperature from Celsius to Kelvin. In such conversions, the formula to be used is T(K) = T(°C) + 273.15. In this case, you are given the temperature in Celsius (18°C). So the calculation will be as follows:

T(K) = 18°C + 273.15 = 291.15 K

Since we don't have 291.15 K in the options and Kelvin values are usually rounded to the nearest whole number, the answer is 291 K.
