\(\frac { { T }_{ 1 }+{ T }_{ 2 } }{ 2 } \)
\(\frac { { T }_{ 1 }{ T }_{ 2 }\left( { P }_{ 1 }{ V }_{ 1 }+{ P }_{ 2 }{ V }_{ 2 } \right) }{ { P }_{ 1 }{ V }_{ 1 }{ T }_{ 2 }+{ P }_{ 2 }{ V }_{ 2 }{ T }_{ 1 } } \)
\(\frac { { T }_{ 1 }{ T }_{ 2 }\left( { P }_{ 1 }{ V }_{ 1 }+{ P }_{ 2 }{ V }_{ 2 } \right) }{ { P }_{ 1 }{ V }_{ 1 }{ T }_{ 1 }+{ P }_{ 2 }{ V }_{ 2 }{ T }_{ 2 } } \)
4.
Cv & CP denote the molar specific heat capacities of a gas at constant volume and constant pressure then ________________.
Cp - Cv is larger for a diatomic ideal gas than for a monoatomic ideal gas
Cp, + Cv is larger for a diatomic ideal gas than for a monoatomic ideal gas
Cp, / Cv is larger for a diatomic ideal gas than for a monoatomic ideal gas
Cp, x Cv is lesser for a diatomic ideal gas than for a monoatomic ideal gas
5.
When an ideal diatomic gas is heated at constant pressure, the fraction of the heat energy applied which increases the internal energy of gas is _____________.
