The gas inside a cylinder expands against a constant external pressure of 0.991 atm from a volume of 3.65 L to a volume of 14.60 L. In doing so, it turns a paddle immersed in 0.908 L of liquid benzene (C6H6). 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 CgH, to be 0.879 g cm3 and its specific heat to be 1.74 J °C- g. Hints: The expansion work done by the gas is given by: w = -P external AV and 1 L atm = 101.325 J. AT = °C

A 0.210 g sample of a metal, M, reacts completely with sulfuric acid according to the reaction M(s)+H2SO4(aq)⟶MSO4(aq)+H2(g) A volume of 219 mL of hydrogen gas is collected over water; the water level in the collecting vessel is the same as the outside level. Atmospheric pressure is 1.0079 bar and the temperature is 25 °C. The vapor pressure of water at 25 °C is 0.03167 bar. Calculate the molar mass of the metal.
A vehicle airbag system works by using a series of chemical reactions. When sensors in the system detect a collision, a heat source instantly causes the decomposition of sodium azide at 300oC. This first reaction produces sodium metal and nitrogen gas. The formation of the nitrogen gas inflates the airbag, but unfortunately, the other product, sodium metal, is extremely dangerous and highly reactive. The sodium metal must undergo an immediate secondary reaction to transform into a safer substance. That’s where potassium nitrate gets involved. In the secondary reaction, sodium metal reacts with the potassium nitrate to form potassium oxide, sodium oxide, and additional nitrogen gas. This secondary generation of nitrogen gas also fills the airbag. Excess gas from the secondary reaction gets vented from e airbag. Finally, in the third and fourth reactions, the sodium oxide and potassium oxide react with silicon dioxide separately to product harmless and stable silicate glasses sodium…
Q1
When air expands adiabatically (without gaining or losing heat), its pressure P and volume V are related by the equation PV14 = C where C is a constant. Suppose that at a certain instant the volume is 310 cubic centimeters and the pressure is 87 kPa and is decreasing at a rate of 8 kPa/minute. At what rate in cubic centimeters per minute is the volume increasing at this instant? cm3 min (Pa stands for Pascal it is equivalent to one Newton/(meter squared); kPa is a kiloPascal or 1000 Pascals.
Xenon and helium are both ideal, monatomic gases, but they have very different molar masses (Mxenon = 33*Mhelium). If you have 1 mole of each gas and the gases are at the same temperature, which one of the following statements is true? They both have the same internal energy, but xenon has a lower root-mean-square speed than helium. They both have the same internal energy and root-mean-square speed. They both have the same root-mean-square speed, but xenon has a greater internal energy than helium. They both have the same internal energy, but helium has a lower root-mean-square speed than xenon. They both have the same root-mean-square speed, but helium has a greater internal energy than xenon.
