Let 25.5 Joule of heat be added to a particular ideal gas. As a result, its volume changes from 54.0 to 118.8 cm3 while the pressure remains constant at 1.0 atm.
Find by how much did the internal energy of the gas change?
Find the molar specific heat at constant pressure?
Evaluate the molar specific heat at constant volume.
Sam, whose mass is 77kg , takes off across level snow on his jet-powered skis. How far has Sam traveled when he finally coasts to a stop
A radio tuner is built by connecting an L=0.41mH inductor and variable capacitor in series with an antenna. The driving voltage is provided by the radiowaves that pass through the antenna, and the total internal resistance of the circuit is R=1.2O..
Two waves traveling on a string in the same direction both have a frequency of 141 Hz, a wavelength of .43 m, and an amplitude of .16 m. What is the amplitude of the resultant wave if the original waves differ in phase by n/4 rads?
One liter of helium at STP is heated at constant volume to 100 C. It is then allowed to mix in an insulated container with one liter of methane which is initially at STP, the final volume being two liters.
What is the frictional force
