If you want to find the latent heat of fusion, you take a cup with 0.755 kg of water at 30.00 C and drop 0.0850 kg of ice initially at 0.000 C and it all reaches an equilibrium temperature of...

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...

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?

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...

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...

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...

Excluding stoppages the speed of a bus is 54km/hr and including stoppages it is 45 km/hr. For how many minutes the bus stop per hour.

Hello,   I'm taking a summer course in college physics and am reviewing some practice questions to prepare for my oncoming exam. I'd really appreciate some help on this question that...

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...

I have some difficulties solving the weak form of the PDE: The proof of the preceding statement is elementary. The weak form of the PDE ∇·(A(x)∇u)+ω^2*q(x)*u = 0 for all φ that vanish at ∂?. Could...
