- Q1Which of the following describes the relationship between pressure, volume, and temperature according to the combined gas law?P + V + T = constantP/V = TPV = nRTPV/T = constant30s
- Q2In a scenario where the temperature of a gas is increased while the volume remains constant, what happens to the pressure of the gas according to the combined gas law?The pressure becomes zeroThe pressure remains constantThe pressure decreasesThe pressure increases30s
- Q3If the volume of a gas is doubled while the temperature remains constant, how does the pressure change according to the combined gas law?The pressure doublesThe pressure remains the sameThe pressure is halvedThe pressure is quadrupled30s
- Q4What is the primary purpose of using the combined gas law in gas calculations?To determine the density of a gasTo calculate the mass of a gasTo find the chemical composition of a gasTo relate pressure, volume, and temperature of a gas30s
- Q5Which of the following scenarios best illustrates the combined gas law in real life?A tire inflating as the temperature increases.A balloon expands as it rises in the atmosphere.A pot of water boiling on the stove.A soda can losing its fizz when opened.30s
- Q6In which situation would the combined gas law primarily apply?A sealed syringe's volume decreases as the temperature increases.An ice cube melting in a glass of warm water.A kettle steaming when water heats up.A car tire bursting due to overinflation in the heat.30s
- Q7Which example demonstrates the combined gas law when discussing the behavior of gases?Water boiling at different altitudes.A basketball deflating on a cold day.A helium balloon floating higher as it warms up.A tire being filled with air before a road trip.30s
- Q8Which situation best illustrates the combined gas law in action?A sealed jar of gas decreases in volume when placed in a refrigerator.A glass of cold lemonade sweating on a hot day.An aerosol can releasing gas at room temperature.A car engine overheating during long drives.30s
- Q9Which of the following scenarios is an example of the combined gas law at work?A sealed bag of chips puffing up when brought to a higher altitude.A storm cloud forming and releasing rain.An ice cube forming in a freezer.A cup of coffee cooling down on a table.30s
- Q10In which scenario can you observe the combined gas law in action?A can of whipped cream expands when exposed to warmer temperatures.An ice cream cone melting on a hot day.A balloon deflating when left outside in the cold.A fish tank bubbling when air is pumped into it.30s
- Q11Which example effectively demonstrates the combined gas law in a real-life context?A candle blowing out in a draft.Water freezing into ice cubes in a freezer.A fizzy drink spilling when opened.A pressure cooker allowing steam to build up as it heats.30s
