Chapter 18: Q. 11 (page 510)

The temperature increases from 300 K to 1200 K as a gas undergoes

the process shown in FIGURE Q18.11. What is the final

pressure?

Short Answer

Expert verified

The final pressure of gas = 8 atm

Step by step solution

01

Visualisation

The ideal gas equation can be used in this problem.

In the ideal gas equation,

PV=nRT

Here, localid="1648461240466" P,V,n,R&Tare respectably pressure, volume, number of moles, universal gas constant and absolute temperature of gas.

In the given problem, V,n&Rare constants.

So,

localid="1648462419830" P鈭�TP2P1=T2T1P2=T2T1P1

Here, P1&T1are the initial pressure & temperature and P2&T2are the final pressure & temperature.

02

Step: 2  Calculation of the final pressure of gas

As given in the question,

T1=300K,T2=1200K,P1=2atm

Then,

P2=T2T1P1=1200K300K2atm=8atm

So, 8 atm is the final pressure of gas.

The cylinder in FIGURE Q18.4 is divided into two compartments by a frictionless piston that can slide back and forth. If the piston is in equilibrium, is the pressure on the left side greater than, less than, or equal to the pressure on the right? Explain.

FIGURE Q18.4

A gas under goes the process shown in FIGURE Q18.10. By what factor does the temperature change?

The atomic mass number of copper is A = 64. Assume that atoms in solid copper form a cubic crystal lattice. To envision this, imagine that you place atoms at the centers of tiny sugar cubes, then stack the little sugar cubes to form a big cube. If you dissolve the sugar, the atoms left behind are in a cubic crystal lattice. What is the smallest distance between two copper atoms?

a. A sample of water vapour in an enclosed cylinder has an initial pressure of 500 Pa at an initial temperature of -0.01掳C. A piston squeezes the sample smaller and smaller, without limit. Describe what happens to the water as the squeezing progresses.

b. Repeat part a if the initial temperature is 0.03掳C warmer.

Two students each build a piece of scientific equipment that uses a 655 mm-long metal rod. One student uses a brass rod, the other an invar rod. If the temperature increases by 5.0掳C, how much more does the brass rod expand than the invar rod?
