Rivets can be cooled before they are put in place, thus when they reach equilibrium temperature they are more firmly fixed in place. If the volume expansion of iron is 35.0 X 10-6...
Consider a common refrigerator in a standard home, where the temperatures are 22.0 C in the home and the refrigerator is kept slightly above freezing. If a 0.750 kg ice cube initially at 0.00 C is allowed...

I am having problems with this problem
Calorimetry a. How much heat needs to be taken from 0.5 kg of ethyl alcohol as a gas at its boiling point of 78.0 C to a solid at its freezing point -114 C if the latent heat of vaporization...
Kinetic theory a. What is the average kinetic energy of a monatomic gas at a temperature of 354 K? b. If this is Ne gas (neon has 20 nucleons) what is the root-mean-squared speed...
In considering density and buoyancy, a helium balloon floats in air even as wood floats on water. A father was bringing home balloons for a party and had attached the balloons to the seat of a van...
The electric potential increases from 72 V to 686 V from the bottom plate to the top plate of a parallel plate capacitor. What is the magnitude of the change in potential energy of a -3 X 10^-6 C...

If a 0.06247 kg ice cube initially at 0.00 C is allowed to melt in a Styrofoam cup holding 0.497 kg of water at 10.0 C , what is the total entropy change for this process?
Consider a common refrigerator in a standard home, where the temperatures are 22.0 C in the home and the refrigerator is kept slightly above freezing. If a 0.750 kg ice cube initially at 0.00...
Derive velocity of forward propagation = wavelength x frequency, probably deriving it from the formula for angular motion. 2 speakers, 1 behind the other, same hertz. Someone walking towards...
I was given this worksheet in class and my professor refuses to explain it to us. I need help!! For the given sample: Wooden cube (rectangular). Measure its mass in grams...
What is the mechanical advantage of a claw foot hammer having a handle with a length of 45 cm and head length of 10 cm? a. 1/9 b. 2/9 c. 2/5 d. 5/2 e. 9/2 f...
At a dilapidated playground, people have stolen the support bar to a merry-go-round leaving a flat disk that can rotate freely. While pondering conservation of angular momentum, a curious physics...
