Which statement best explains why the pressure increases inside a rigid container of gas if the temperature is suddenly increased? Group of answer choices 1. Gas molecules move faster and the frequency and force of collisions against the container walls increases. 2. The increased temperature causes the gas molecules to attract one another which reduces the frequency and force of collisions against the container walls. 3. Gas molecules move slower and the frequency and force of collisions against the container walls decreases. 4. The increased temperature causes the gas to change composition therefore the temperature increases.

How does gas respond in changes in temperature and pressure

Two moles of an ideal gas are placed in a container of ridged container and the pressure increases. What must happen to the temperature? Explain.

Which of the following is true about the relationship between the volume and pressure of a gas? a. As the volume of a gas decreases, the molecules collide less frequently and the pressure decreases. O b. As the volume of a gas decreases, the molecules collide less frequently and the pressure increases. c. As the volume of a gas decreases, the molecules collide more frequently and the pressure decreases. d. As the volume of a gas decreases, the molecules collide more frequently and the pressure increases.

Three samples of three different gases are listed in the table below. All the samples contain exactly 1 mole of gas and are at a temperature of -5.0°C. For each sample, decide whether the gas can be reasonably described as an ideal gas. If the gas isn't ideal, decide the most important reason why it isn't. sample A B C pressure (atm) 0.99 0.70 0.73 volume (L) 20.0 25.0 30.0 ideal? O yes O no O yes O no O yes O no If not ideal, the most important reason why not: O There are attractions between the particles. The particles don't have zero volume. There are attractions between the particles. O The particles don't have zero volume. O There are attractions between the particles. O The particles don't have zero volume.

1.) A closed container contains equal molar amounts of 02 and CO2 gas and the total pressure is 500 mmHg. What is the partial pressure of O2? a. 1000 mmHg b. 500 mmHg c. 250 mmHg d. 176 mmHg

Why does volume increase when pressure and temperature remain constant? What has happened to the gas?

Which of the following would increase the pressure of a gas? A. Increase the volume of the container B. Decrease the temperature of the gas C. Decrease the volume of the container D. None of the above

Three samples of three different gases are listed in the table below. All the samples contain exactly 1 mole of gas and are at a temperature of -10.0°C. For each sample, decide whether the gas can be reasonably described as an ideal gas. If the gas isn't ideal, decide the most important reason why it isn't. sample A B C pressure (atm) 1.9 1.7 0.86 volume (L) 10.0 15.0 20.0 ideal? O yes no O yes O O no yes no If not ideal, the most important reason why not: O There are attractions between the particles. O The particles don't have zero volume. O There are attractions between the particles. O The particles don't have zero volume. There are attractions between the particles. O The particles don't have zero volume. X 5
