A mixture of helium and neon gas is expanded from a volume of 77.0L to a volume of 87.0L, while the pressure is held constant at 27.0atm. Calculate the work done on the gas mixture. Round your answer to 3 significant digits, and be sure it has the correct sign (positive or negative).
A cylinder contains one liter of air at room temperature (300 K) and atmospheric pressure (105 N/m2). At one end of the cylinder is a massless piston, whose surface area is 0.01 m2 . Suppose that you push the piston in very suddenly, exerting a force of 2000 N. The piston moves only one millimeter, before it is stopped by an immovable barrier of some sort. How much work have you done on this system?
The average electricity consumption of a house in Gainesville is known to be 1,007 kWh in a month (One month = 30 days). They would like to install solar panels of 29 % efficiency to generate this electricity. Given that the average solar power density in Gainesville is 5.47 kWh/m2/day, how much surface area must the panels occupy? Calculate the result in m2 but do not write the unit. Round off %3D you answer to a whole number (zero decimal place.)
One mole of an ideal gas is heated slowly so that it triples its volume and pressure, in such a way that the pressure of the gas is directly proportional to its volume (linear relationship). Whats the work consumed by the gas?
A gas expands from an initial volume of 0.40 m3 to a final volume of 0.62 m3 as the pressure increases linearly from 110 kPa to 230 kPa. Find the work done by the gas.
As a gasoline engine is running, an amount of gasoline containing 13,600 J of chemical potential energy is burned in 1 s. During that second, the engine does 3,400 J of work. (a) What is the engine's efficiency (in percent)? % (b) The burning gasoline has a temperature of about 4,100°F (2,500 K). The waste heat from the engine flows into air at about 90°F (305 K).

Archimedes tells us the lifting power of a balloon (how much mass it can lift) is equal to the difference between the mass of the balloon and the mass of the air it displaces. That is, if the balloon occupies the same volume as 10 kg of air, but the balloon only weighs 2 kg, then the balloon can lift 8 kg. Airships have sometimes been filled with hydrogen (H2), but hydrogen is very flammable, and after the Hindenburg caught fire and crashed in 1937 with serious loss of life airships have nearly always been filled with helium (He) instead. gas H₂ density 0.090 kg 3 m kg He 0.18 3 m kg 1.23 3 P air m Suppose a new airship Star of Balogna will have the shape of a cylinder 100. m long, with a radius of 15.0 m, and will weigh 9200. kg without any gas inside it.
