The gauge pressure in an automobile tire reads 32 psi in the winter at 32 degrees Fahrenheit the gauge reads the difference between the tire pressure and the atmospheric pressure (14.7 psi). In other words, the pressure in the gauge reading plus 14.7 psi. if the same tire were used in the summer at 110 degrees Fahrenheit and no air leaked from the tire, what would be the tire gauge reading in the summer?
using any diagrams that you wish to draw, explain how the Ocean Optics spectrophotometer works. Note: we are not asking how to operate the spectrophotometer.
calculate the work if the gas is now re-compressed to 2liter by reapplying the 8bar of pressure. assume that the process is carried out reversibly and isothermally

A 285- flask contains pure helium at a pressure of 750 . A second flask with a volume of 470 contains pure argon at a pressure of 716 .If the two flasks are connected through a stopcock and the stopcock is opened, what is the partial pressure of h..
Chemical Structure and Hydrogen Bonds in Base Pairs, Draw the chemical structure of a correctly base paired G-C pair, then re-draw the pair with a propeller twist these answers should all be on one page following box G.
Suppose you inserted a piece of copper into a solution of nickel chloride and observed no reaction. Then if you inserted a piece of iron into the solution of nickel chloride a nickel deposit formed on the bottom of the well in the well plate.
A buffering system in the blood is H2CO3/HCO4. At the normal blood pH (7.4) a solution of H2CO3 and HCO3 will change the pH abruptly if small amounts of acid or base are added since the pKa of H2CO3 is 6.4.
