Consider a mixture of air and gasoline vapor in a cylinder with a piston. The original volume is 40. cm3. If the combustion of this mixture releases 950. J of energy, to what volume will the gases expand against a constant pressure of 650. torr if all the energy of combustion is converted into work to push back the piston

Explanation:

Given :

Initial volume Lit.

Energy J = 9.38 Lit × atm.   ⇒ ( 1 Lit×atm. = 101.325 J )

Pressure 650 torr = 0.855 atm. ⇒ ( 1 torr = 0.00132 atm )

In this example we have to be aware of unit conversion system.

From the laws of thermodynamics,

Here in this example, all the energy of combustion is converted into work to push back the piston

Lit =

where's the following? you gotta add it to know what the choices are
