Chapter 12, Problem 14PE

(a)

Interpretation Introduction

Interpretation:

Final volume of CH4 gas if temperature is changed from 25 °C to 298 K has to be determined.

Concept Introduction:

Charles’ law represents direct relation of volume of fixed mass of ideal gas with its temperature at fixed pressure.

Mathematically relation for Charles’ law is as follows:

  VT

Or,

  V1T1=V2T2

Here,

T1 is initial temperature.

T2 is final temperature.

V1 is initial volume.

V2 is final volume.

Answer to Problem 14PE

Final volume of CH4 gas is 0.690 L.

Explanation of Solution

Expression to calculate final volume of gas is as follows:

  V2=V1T2T1        (1)

Conversion factor to convert 25 °C to Kelvin is as follows:

  T(K)=temperatureincelsius+273=25 °C+273=248K

Substitute 575 mL for V1, 248K for T1, and 298K for T2 in equation (1).

  V2=((575 mL)(298K)248K)(1 L103 mL)=0.690 L

Hence final volume of CH4 gas is 0.690 L.

(b)

Interpretation Introduction

Interpretation:

Final volume of CH4 gas if temperature is changed from 25 °C to 32 °F has to be determined.

Answer to Problem 14PE

Final volume of CH4 gas is 0.633 L.

Explanation of Solution

Expression to calculate final volume of gas is as follows:

  V2=V1T2T1        (1)

Conversion factor to convert 25 °C to Kelvin is as follows:

  T(K)=temperatureincelsius+273=25 °C+273=248K

Conversion factor to convert degree Fahrenheit to Celsius is as follows:

  T(°C)=59(T(°F)32)        (2)

Substitute 32 °F in equation (2).

  T(°C)=59(32 °F32)=0 °C

Conversion factor to convert 0 °C to Kelvin is as follows:

  T(K)=temperatureincelsius+273=0 °C+273=273K

Substitute 575 mL for V1, 248K for T1, and 273K for T2 in equation (1).

  V2=((575 mL)(273K)248K)(1 L103 mL)=0.633 L

Hence final volume of CH4 gas is 0.633 L.

(c)

Interpretation Introduction

Interpretation:

Final volume of CH4 gas if temperature is decreased from 25 °C to 45 °C has to be determined.

Concept Introduction:

Refer to part (a).

Answer to Problem 14PE

Final volume of CH4 gas is 0.737 L.

Explanation of Solution

Expression to calculate final volume of gas is as follows:

  V2=V1T2T1        (1)

Conversion factor to convert 25 °C to Kelvin is as follows:

  T(K)=temperatureincelsius+273=25 °C+273=248K

Conversion factor to convert 45 °C to Kelvin is as follows:

  T(K)=temperatureincelsius+273=45 °C+273=318K

Substitute 575 mL for V1, 248K for T1, and 318K for T2 in equation (1).

  V2=((575 mL)(318K)248K)(1 L103 mL)=0.737 L

Hence final volume of CH4 gas is 0.737 L.
