During a breath, the average human lung expands by about 0.50 L.
If this expansion occurs against an external pressure of 1.0 atm, how much work (in J) is done during the expansion?
Express your answer using two significant figures.

How many joules of net work does this person's lung do during one complete breath? Express your answer to three significant figures and include the appropriate units Constants Work Done by the Lungs. The graph (Figure 1) shows a pv diagram of the air in a human lung when a person is Inhaling and then esthaling a deep breath Such graphs, obtained in clnical practice, are normally somewhat curved, but we have modeled one as a set of straight lines...
A cylinder equipped with a piston expands against an external pressure of 1.61 atm . If the initial volume is 0.515 L and the final volume is 1.260 L , how much work (in J) is done?
A cylinder equipped with a piston expands against an external pressure of 1.64 atm . If the initial volume is 0.535 L and the final volume is 1.290 L , how much work (in J) is done
A cylinder with a moving piston expands from an initial volume of 0.250 L against an external pressure of 2.00 atm. The expansion does 288 J of work on the Surroundings. What is the final volume of the cylinder?

A gas expands from 5.7 L to 8.1 L at constant temperature. Calculate the work done by the gas if it expands against a constant external pressure of 0.98 atm. Answer in units of joules.
How much work (in J) is required to expand the volume of a pump from 0.0 L to 2.5 L against an external pressure of 1.1 atm? Express your answer using two significant figures.
Suppose you take and hold a deep breath on a chilly day, inhaling 2.5 L of air at O degree C. Assume that air pressure is 1.0 atm. How much heat must your body supply to warm the air to your internal body temperature of 37 degree C? Assume that for air C_p = 29.1 J/(K middot mol) as it consists mostly of nitrogen and oxygen. Express your answer to two significant figures and include the appropriate units. Q =...
The gas inside a cylinder expands against a constant external pressure of 0.953 atm from a volume of 4.51 L to a volume of 14.50 L. In doing so, it turns a paddle immersed in 0.962 L of liquid toluene (C7H8). Calculate the temperature rise of the liquid, assuming no loss of heat to the surroundings or frictional losses in the mechanism. Take the density of liquid C7H8 to be 0.867 g cm-3 and its specific heat to be 1.69...
