One method of converting heat transfer to doing work is for heat transfer into a gas to take place, which expands, dong work on a piston, as shown in the figure below. (a) Is the heat transfer converted directly to work in an isobaric process, or does it go through another form first? Explain your answer. (b) What about in an isothermal process? (c) What about in an adiabatic process (where heat transfer occurred prior to the adiabatic process)?
Under what circumstances would you expect a gas to behave significantly differently than predicted by the ideal gas law?
Does a real gas exert more or less pressure than a ideal gas? Explain
Is the total energy of the universe becoming more unavailable with time? Explain.
It is said that expansion of an ideal gas into a vacuum results in no work done. Is this the case with real gas? Explain
For an isothermal compression of a gas, is it more efficient to compress in a single step or an infinite number of steps? Why? (2-3 sentences or a sketch on a PV curve or a quick calculation will do). 2. If you have 1.0 moles of Ne atoms at 2atm and 315K and you want to heat it to 375K, would the process exchange more heat if it is done isochorically or if it is done isobarically? Justify your answer. 3. For the process you selected in number two, calculate the work, heat, enthalpy change and internal energy change for your process.
The temperature difference between the hot and cold fluids in a heat exchanger is given to be DT1 at one end and DT2 at the other end. Can the logarithmic temperature difference DTlm of this heat exchanger be greater than both DT1 and DT2? Explain.
On a clear bright sunny day against the blue sky, a red ballon isallowed to rise while maintaining a constant temperature of 27°C.The ballon contains 0.3 moles of Helium gas. It rises to an altitudewhere its volume has expanded five times. Neglecting other forcesin the ballon, find the work done by the helium gas?(a) 2500 J (b) -2500J (c) 1200 J (d) -1200 J
A gas follows on an isothermal curve, where p is the pressure, V is the volume, b is a constant, and c is a function of temperature. Show that a temperature scale under an isochoric process can be established with this gas and is identical to that of an ideal gas.
Suppose a gasfilled incandescent light bulb is manufactured so that the gas inside the bulb is at atmospheric pressure when the bulb has a temperature of 20.0C. (a) Find the gauge pressure inside such a bulb when it is hot, assuming its average temperature is 60.0C (an approximation) and neglecting any change in volume due to thermal expansion or gas leaks. (b) The actual final pressure for the light bulb will be less than calculated in part (a) because the glass bulb will expand. What will the actual final pressure be, taking this into account? Is this a negligible difference?
(a) People often think of humid air as "heavy." Compare the densities of air with 0% relative humidity and 100% relative humidity when both are at 1 atm and 30 . Assume that the dry air is an ideal gas composed of molecules with a molar mass of 29.0 g/mol and the moist air is the same gas mixed with water vapor. (b) As discussed in the chapter on the applications of Newton's laws, the air resistance felt by projectiles such as baseballs and golf balls is approximately FD=CpAv2/2 , where p is the mass density of the air, A is the cross-sectional area of the projectile, and C is the projectile's drag coefficient. For a fixed air pressure, describe qualitatively how the range of a projectile changes with the relative humidity. (c) When a thunderstorm is coming, usually the humidity is high and the air pressure is low. Do those conditions give an advantage or disadvantage to home-run hitters?
An ideal diatomic gas at 80 K is slowly compressed adiabatically and reversibly to twice its volume. What is its final temperature?
