Consider an ideal gas enclosed in a 1.00 l container at an internal pressure of 18.0 atm. calculate the work, w , if the gas expands against a constant external pressure of 1.00 atm to a final volume of 18.0 l.

-32821.2 J (negative sign implies that work is done by the system)

Explanation:

The expression for the calculation of work done is shown below as:

Where, P is the pressure

is the change in volume

From the question,  

= 18.0 - 1.00 L = 18.0 L

P = 18.0 atm

Also, 1 atmL = 101.3 J

So,  

(negative sign implies that work is done by the system)

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
