If the pressure of 8.0 L of nitrogen gas in a flexible container is decreased to one-fifth of its orginal pressure(at constat teperature)' the volume will now be ?

Assume tat you have a sample of a gas in a cylinder with a movable piston at constant pressure. Determine the volume of the gas if the absolute temperature is decreased by twenty-five percent.

the temperature of a gas in sealed container changes from 20. c to 40.0 C. If the volume remains constant,the pressure will change from 660 torr to ?

Since ethanol is cheaper than gasoline , today's gasoline's contain varying amonts of ethanol to keep prices lower. given that the enthalpy of combustion of ethanol is -1367 kj/mole and that the aveage energy released by one gram of gasoline is 43 kj: ) C...

Larger amounts of methane, in the form CH4*6H20 is trapped at the bottom of the ceans in Clatharate compunds (formed when small molecules occupy the empty spaces in cage like structures). Calculate the mass of methane gas trapped with in one Kg of the hyd...

The space shuttle uses fuel cells( AFC's) to produce electricity . In these fuel cells,O2 reacts with water and electrons to produce OH- ioins travel to the other electrode where they react with H2 to release electrons and produce more water. Based on thi...
