Which is a postulate of the kinetic-molecular theory?

A. Gas particles have a small volume relative to the spaces between them.

Which sequence describes the result of increasing the temperature of a gas in a container?

A. Higher kinetic energy ® greater collision force ® higher pressure.

When the process of condensation occurs, the kinetic energy of particles

A. Is insufficient to overcome intermolecular forces.

A gas has a temperature of 273.15 K and a pressure of 101.325 kPa. What can be concluded about the gas?

A. It has reached standard temperature and pressure.

Which is an aspect of the kinetic-molecular theory and can be used to explain the compressibility of plasmas?

A. Particles move independently of one another and are widely spaced.

The ideal gas constant, R has several different values that could be used. Which quantity causes these differences?

A. Pressure

Why do amorphous solids not have a long-range order in the arrangement of their particles?

A. Their formation involves very rapid cooling.

A scientist is examining a mixture of nitrogen, hydrogen, and ammonia. The individual pressures that are exerted by nitrogen and hydrogen are 0.26 atm and 0.28 atm, respectively. If the total pressure is 0.90 atm, what is the partial pressure of ammonia?

B. 0.36 atm

Which best characterizes a crystal?

B. A dense substance that is hard and incompressible.

Shana solves stoichiometry problems using the equation for the synthesis of water. Which interpretation of the balanced equation would cause Shana to make a mistake?

B. Two grams of hydrogen react with one gram of oxygen to form two grams of water.

Which proportionality shows the result of combining Avogadro's law with Boyle's law?

B. V& N/P

Which commercial technology commonly uses plasmas?

C. A television.

Which units of pressure are equivalent and require no conversion of the value?

C. MmHg and torr

Which sequence represents the relationship between pressure and volume of an ideal gas as explained by the kinetic-molecular theory?

C. Smaller volume -> crowded particles -> more collisions -> higher pressure.
