Question

Convert 80.92 °C to K and °F.

Step-by-Step Solution

Answer

The temperature 80.92⁰C can be converted to 354.07 K and 177.7 °F.

Step1: Definition of Fahrenheit

A Fahrenheit scale is a temperature scale based on the proposal by the physicist Daniel Gabriel Fahrenheit in 1724. The degree Fahrenheit is the unit of measurement.

Step 2: Definition of Celsius

The degree Celsius can refer to a specific temperature on a Celsius scale or a unit used to denote a difference or range of temperatures between two temperatures.

Step 3: Definition of Kelvin

A Kelvin temperature scale is a temperature scale with an absolute zero, below which no temperatures exist. Absolute zero, or 0°K, is the temperature at which a molecular energy is at its lowest, and it corresponds to a temperature of 273.15° Celsius.

Step 4: Calculation

(a) Celsius to Kelvin:

X °c + 273.15 = x k.

    80.92°C + 273.15 = 354.07 K.

     (b) Celsius to Fahrenheit:

           (X °c x  ) + 32 = x F

     (80.92°C ×  ) + 32 = 177.656°F.
