Chapter 3: Q2DQ (page 609)

In the ideal-gas equation, could an equivalent Celsius temperature be used instead of the Kelvin one if an appropriate numerical value of the constant Ris used? Why or why not?

Short Answer

Expert verified

The answer will be NO for the tworeasons

The firstreasonis thetemperatureThereis in a certaintemperaturenot a difference

second Reason is by taking the pressure and volume could be in minus

Step by step solution

01

Determine the ideal Gas Equation

The ideal gas law is the equation of state of a hypothetical ideal gas.It is a good approximation of the behaviour of many gases under many conditions, although it has several limitations

02

Justify Celsius temperature be used instead of the Kelvin

The answer will be NO for the tworeasons

Take look at ideal gas equation

ThetemperatureThereis in a certaintemperaturenot a difference

between two values of thetemperatureandratio betweentwo values .so it will be difficult to use Celsius instead of kelvin .becauseof many decrease intemperaturefrom K to byb 273 will affect the real value of the pressure and volume

Anotherreasonis The minimum value oftemperaturein kelvin is absolute zero while incelsiusthetemperaturewill be in negative also .By sub with the value of T inequationof state thepressureand volumecouldbe in minus and as we know there is nopressureand volume in negative

Therefore ,The firstreasonis thetemperatureThereis in a certaintemperaturenot a difference

second Reason is by taking the pressure and volume could be in minus

You hold an inflated balloon over a hot-air vent in your house and watch it slowly expand. You then remove it and let it cool back to room temperature. During the expansion, which was larger: the heat added to the balloon or the work done by the air inside it? Explain. (Assume that air is an ideal gas.) Once the balloon has returned to room temperature, how does the net heat gained or lost by the air inside it compare to the net work done on or by the surrounding air?

Does a refrigerator full of food consume more power if the room temperature is 20掳Cthan if it is15掳C? Or is the power consumption the same? Explain your reasoning.

The units of specific heat care J/kg路K, but the units of heat of fusion Lfor heat of vaporization Lv are simply J/kg. Why do the units of Lfand Lv not include a factor of (K)鈥�1 to account for a temperature change?

A thermodynamic system undergoes a cyclic process as shown in Fig. Q19.24. The cycle consists of two closed loops: I and II. (a) Over one complete cycle, does the system do positive or negative work? (b) In each loop, is the net work done by the system positive or negative? (c) Over one complete cycle, does heat flow into or out of the system? (d) In each loop, does heat flow into or out of the system? Explain

If the pressure of an ideal monatomic gas is increased while the number of moles is kept constant, what happens to the average translational kinetic energy of one atom of the gas? Is it possible to change boththe volume and the pressure of an ideal gas and keep the average translational kinetic energy of the atoms constant? Explain.
