Chapter 20: Q. 2 (page 566)

Gases, in contrast with solids and liquids, are very compressible. What can you infer from this observation about the microscopic nature of gases?

Short Answer

Expert verified

In case of gases, the atoms are far away from each other. As a result, gases are highly compressible.

Step by step solution

Given Information

Gases are highly compressible compared to liquids and solids.

Finding the reason behind the high compressibility of gases

In case of Gases, the compressibility is seen to be high. From this observation, it can be inferred that the atoms in gas are far away from each other and repulsion power among the atoms are not as strong as compared to solids. As a result, gases are highly compressible.

7. Suppose you could suddenly increase the speed of every molecule in a gas by a factor of 2.

a. Would the temperature of the gas increase by a factor of $2^{1 / 2}, 2$ or $2^{2} ?$ Explain.

b. Would the molar specific heat at constant volume change? If so, by what factor? If not, why not?

Scientists studying the behavior of hydrogen at low temperatures need to lower the temperature of $0.50 m o l$ of hydrogen gas from $300 K$ to $30 K$ . How much thermal energy must they remove from the gas?

6. Suppose you could suddenly increase the speed of every molecule in a gas by a factor of 2.

a. Would the RMS speed of the molecules increase by a factor of $2^{1 / 2}, 2, o r 2^{2}$ ? Explain.

b. Would the gas pressure increase by a factor of $2^{1 / 2}, 2$ or $2^{2}$ ? Explain.

By what factor does the $r m s$ speed of a molecule change if the temperature is increased from $10 ° C$ to $1000 ° C$ ?

A $1.0 m \times 1.0 m \times 1.0 m$ cube of nitrogen gas is at $20 ° C$ and $1.0 a t m .$ Estimate the number of molecules in the cube with a speed between $700 m / s$ and $1000 m / s$ .
