- Q1What is the ideal gas law equation?PV=nRTP=Vn/RTPV=RT/nPV=n/T30s
- Q2What is Boyle's law?For a fixed amount of gas at a constant temperature, the product of the pressure and volume is constant.As temperature increases, so does volume.As the amount of gas increases, so does volume.As pressure increases, so does volume.30s
- Q3What is Charles's law?For a fixed amount of gas at a constant pressure, the volume is directly proportional to its absolute temperature.As pressure increases, so does temperature.As volume increases, so does pressure.As temperature increases, so does pressure.30s
- Q4What is Avogadro's law?Equal amounts of gas at the same temperature and pressure contain the same number of molecules.Equal volumes of any gas at different temperatures and pressures contain the same number of molecules.Equal volumes of any liquid at the same temperature and pressure contain the same number of molecules.Equal volumes of any gas at the same temperature and pressure contain the same number of molecules.30s
- Q5What is the relationship between pressure and temperature in Gay-Lussac's law?As temperature increases, pressure increases.For a fixed amount of gas at a constant volume, the pressure is directly proportional to the absolute temperature.As pressure increases, temperature decreases.As the amount of gas increases, pressure increases.30s
- Q6What is the standard temperature and pressure?0 K and 1 Pa25 °C and 1 atm100 °C and 1 atm0 °C and 1 atm30s
- Q7What is the difference between a gas and a vapor?A gas is a mixture of different gases while a vapor is a single substance.A gas has a definite volume while a vapor does not.A gas can be seen while a vapor cannot.A gas is a substance that is normally in a gaseous state at room temperature and pressure while a vapor is a substance that is normally a liquid or solid at room temperature and pressure but can exist as a gas at higher temperatures or lower pressures.30s
- Q8What is the relationship between the number of moles of gas and its volume?As the pressure increases, the volume increases.As the temperature increases, the volume increases.As the number of moles of gas increases, the volume decreases.For a fixed temperature and pressure, the volume of a gas is directly proportional to the number of moles of gas.30s
- Q9What is the relationship between the volume of a gas and its pressure?As the amount of gas increases, so does the pressure.For a fixed amount of gas at a constant temperature, the volume is inversely proportional to the pressure.As the volume increases, so does the pressure.As the temperature decreases, so does the pressure.30s
- Q10What is the ideal gas law?V=nRT/PPV=nRTP=V/nRTPV=RT/n30s
- Q11What is Avogadro's hypothesis?The volume of gas is directly proportional to its number of molesThe pressure of gas is directly proportional to its number of molesThe number of molecules in a gas is inversely proportional to the temperatureEqual volumes of gases at the same temperature and pressure contain equal numbers of molecules30s
- Q12What is the unit of pressure?Watt (W)Joule (J)Meter (m)Pascal (Pa)30s
- Q13What is the unit of temperature in the Celsius scale?Degree Celsius (°C)Kelvin (K)Fahrenheit (°F)Degree (°)30s
- Q14What is the standard temperature and pressure (STP)?0°C and 0.1 atm25°C and 0.1 atm25°C and 1 atm0°C and 1 atm30s
- Q15What is the molar volume of an ideal gas at STP?22.4 L/mol2.00 L/mol1.00 L/mol10.0 L/mol30s
