Temperature Units

Perform each of the following conversions:

a . 212°F to °C b . 77 K to °F  ( temperature of liquid nitrogen ) c . 25°C to K d . 100°F to K

Interpretation Introduction

Interpretation:

Each of the given conversions is to be performed.

Concept introduction:

Temperature is defined as the measure of hotness and coldness of something.

The formula used to convert oF into oC is as follows:

(oF32)×5/9=oC

Unit conversion is defined as the process in which multiple steps are used to convert the unit of measurement for the same given quantity. It is determined by multiplication with a conversion factor.

The fraction in which numerator and denominator are the same quantities but are determined in different units, is known as a conversion factor.

Explanation of Solution

a) 212oF to oC.

The formula used to convert oF into oC is as follows:

(oF32)×5/9=oC

Conversion of oF into oC is as follows:

T=(oF32)×5/9=(212oF32)×5/9=100oC

Therefore, the conversion of 212oF to oC is 100oC.

b) 77 K to °F (temperature of liquid nitrogen)

Firstly, convert K into °C and then into °F.

Conversion of K into °C is as follows:

77K=°+ 273°C=77 K273 K=196°C

Conversion of °C into °F is as follows:

The formula used to convert °F into °C is as follows:

(°F32)×5/9=°C

°F=9/5(196)+32°F=321
