Question

a thermometer reads 20.5 °c. what is the temperature in kelvin?

Explanation:

Step1: Recall temperature - conversion formula

The formula to convert Celsius to Kelvin is $T(K)=T(^{\circ}C)+ 273.15$.

Step2: Substitute the given Celsius value

Substitute $T(^{\circ}C) = 20.5$ into the formula: $T(K)=20.5 + 273.15$.

Step3: Calculate the result

$T(K)=293.65$.

Answer:

$293.65$
