Question

The difference between $C_{p}$ and $C_{v}$ can be derived using the empirical relation H = U + pV. Calculate the difference between $C_{p}$ and $C_{v}$ for 10 moles of an ideal gas.

Answer 1

"${ C }_{ p } \quadand { C }_{ v }$are two specific heat values at constant pressure and temperature respectively. While "solids" and "liquids" are having "only single value"for "specific heat".

${ C }_{ v }$= "Heat capacity" at "constant volume"

${ C }_{ p }$ = "Heat capacity" at "constant pressure"

The difference between ${ C }_{ p } and { C }_{ v }$is equal to gas constant

${ C }_{ p }\quad -\quad { C }_{ v }\quad =\quad nR$

Here,  

n = number of moles

From the given,

${ C }_{ p } and { C }_{ v }$ difference = 10

${ C }_{ p }\quad -\quad { C }_{ v }\quad =\quad 10\quad \times \quad 8.314$

${ C }_{ p }\quad -\quad { C }_{ v }\quad =\quad 83.14\quad J$"
