# A sample of gas has a volume of 127 mL in a boiling water bath at 1 00   ° C . Calculate the volume of the sample of gas at 1 0   ° C intervals after the heat source is turned off and the gas sample begins to cool down to the temperature of the labmatory 2 0   ° C .

Interpretation Introduction

Interpretation:

Final volume of gas should be determined.

Concept Introduction:

Charles’s law: It is also known as temperature volume relationship. It states that volume of given mass of gas is directly proportional to its temperature.

Explanation

Relation between volume and temperature is given by Charles’s law.

Charles’s law states that volume of given mass of gas is directly proportional to its temperature. As temperature increases volume also increases.

Mathematical expression is:

V1T1=V2T2=k at constant pressure

Initial volume of gas ( V1 ) = 127mL

Initial temperature of gas (T1) = 100C= 273.15+10 =283.15K

Final temperature of gas (T2) =200C=273
