The gases in two identical containers are at 1 atmosphere of pressure and at room temperature. One contains helium gas (monatomic, atomic mass 4) and the other contains an equal number of moles of argon gas (monatomic, atomic mass 40). If 1 joule of heat added to the helium gas increases its temperature a given amount, the amount of heat that must be added to the argon gas to increase its temperature by the same amount is
A) 10 joules
B)√10 joules
C) 1 joule
D) 1/√10 joules
E) 1/10 joules

A bicycle wheel of mass M (assumed to be concentrated at its rim) and radius R is mounted horizontally so it may turn without friction on a vertical axle. A dart of mass mo is thrown with velocity vo above and sticks in the tire.
Two children setup a "telephone" by placing a long, slender aluminium (Y = 6.9 × 1010 N/m2) bar that has a length of 6.1-m between their two houses. To communicate, the child taps a coded message on one end. How long do the sound waves take to reach ..
A balloon contains 0.63 mol of helium. It rises, in maintaining a constant 280 K temperature, to an altitude where its volume has expanded three times. How much work is done by the gas during this isothermal expansion?
