When a gas is heated in a closed container, the internal pressure increases. Which best describes the reason for the increase in pressure? O. The average kinetic energy of the gas molecules decreases. O b The potential energy of the gas decreases. O. The potential energy of the gas increases. The average kinetic energy of the gas molecules increases.

For many purposes we can treat nitrogen (N,) as an ideal gas at temperatures above its boiling point of -196. °C. Suppose the temperature of a sample of nitrogen gas is lowered from 95.0 °C to 58.0 °C, and at the same time the pressure is increased by 5.0%. O increase Does the volume of the sample increase, decrease, or stay the same? O decrease O stays the same If you said the volume increases or decreases, calculate the percentage change in the volume. Round your answer to the nearest percent. % Explanation Check S26 PM P Search for anything 号 12/6/2020 delata %23 3. & backspece 12 5 71 home 8 E Y U tab ULL K enter 4. caps lock pause nits 回 国国

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.

In a sealed and rigid container, a sample of gas at 3.25 atm and 200.0 °C is cooled to 0.0 °C. What is the pressure (in atm) of the gas at 0.0 °C?
