Assume that the temperature, 40c, and volume of the gas, 6 liters, remain constant. at 2 atmosphere of pressure, there are 0.036 moles of the gas. write an equation that describes the pressure on the gas in terms of the amount of gas.

Consider an insulating crystal, made up of layers of atoms. what form would you expect the temperature dependence of the phonon heat capacity to approach at extremely low temperatures if the interlayer coupling is i)very strong (rigid coupling), and ii) very weak. explain.

If the chemical properties of a substance remain unchanged and appearance or shape of a substance changes it is called a ?

You have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 2.70 miss . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?
