Question 33 is the question I’m stuck one
A sample of gas has an initial volume of 28.6 L at a pressure of 1.5 arm. If the sample is compressed to a volume of 13.1 L what will its pressure be? (assume constant temperature) Express your answer using two significant figure
Which of the following statements is true for gases? None of these statements are true. The pressure of a gas is due to collisions of the gas molecules. The temperature of a gas is inversely proportional to its pressure. The volume of a gas is directly proportional to the pressure in torr.
A 1.58 mol sample of N₂ gas is confined in a 38.5 liter container at 23.9 °C. If the temperature of the gas sample is raised to 46.2 °C holding the volume constant, the average molecular speed will O decrease O not enough information to answer the question increase O remain the same Submit Answer Try Another Veralon Use the References to access importars 1 Item attempt remaining
Which gas effuses faster, oxygen or neon? How much faster?
A sample of ideal gas in a flexible-volume container is heated from 25°C to 50°C. If the pressure remains constant, what will happen to the volume as the gas is heated? The volume will increase The volume will decrease The volume will not change
Match the characteristic of gases described below to the postulates of the kinetic molecular theory that best explain that characteristic. (Note: You may need to list more than one postulate.) The pressure of a gas in a fixed volume increases when its temperature increases. Select one or more: The average kinetic energies of gas particles increase with an increase in temperature. Gas particles are widely spaced. A gas consists of many small particles in rapid, random motion. The total volume of the molecules themselves is very small compared to the volume of the container. There are virtually no attractive forces between gas particles.
The average molecular speed in a sample of O2 gas at a certain temperature is 447 m/s. The average molecular speed in a sample of CH4 gas is ____m/s at the same temperature.
