If the pressure of a gas sample is quadrupled and the absolute temperature is doubled, by what factor does the volume of the sample change?
A particle beam is made up of many protons each with a kinetic energy of 3.25×10-15J. A proton has a mass of 1.673×10-27kg and a charge of +1.602×10-19C. What is the magnitude of a u
Determine the final temperature of a gold nugget (mass = 376g) that starts at 398 K and looses 4.85 kj of heat to a snowbankwhen it is lost. The specific heat capacity of gold is 0.128J/g.
A rocketship of proper length d travels at constant velocity v relative to a frame S. The nose of the ship (A') passes the point A in S at t = t' = 0, and at this instant a light signal is sent out
(a) at what horizontal distance from the beetle should the archerfish fire if it is to hit its target in the least time? (b) How much time will the beetle have to react?

A solution containing 0.200 MNH3 and 0.020 M NH4Cl was diluted with water in the proportions shown below (volume solution : volumewater).
A transverse wave is traveling on a string. The displacement y of a particle from its equilibrium position is given by y= (0.021m) sin (25t-2.0x).
What are the magnitude and direction of the ball's velocity when it strikes the wall? Has the ball reached the highest point of its trajectory at this time? Explain.
A train moving with constant velocity travels 170 m north in 12 s and an undetermined distance to the west. The speed of the train is 32 m/s. (a) find the direction of the train's motion relative to
A mono methyl-substituted 1-naphthol is allowed to couple with a diazonium prepared from a mono-substituted hydroxyaniline. How many different coupling products can be obtained assuming all patterns
MTBE is a fuel addictive for gasoline to boost the octanerating. It increases the oxygen content which reduces CO emmissionsto an acceptable level determined by the clean air act.
A student collectedhydrogen gas in a buret by displacing water at 26.0C. the buretcould not be submerged deep enough in a water bath to equilaize the pressure.
Then use Archimedes' principle to find the density required for the air inside the balloon. Then find the temperature of the air inside the balloon.
