| Question | Answer |
|---|---|
| The KMT of gases assumes that the particles of an ideal gas are separated by great distances. This implies that gas particles are considered to have no definite | kinetic molecular theory |
| . Under which conditions does a real gas behave very much like an ideal gas? | High temperatures and low pressure. |
| Which of the following gases would move the slowest? | CO2 because it moves the slowest and has the highest molar mass. |
| . Which factor is the most important in determining the average kinetic energy gas particles? | temperature |
| What will happen to pressure if the force is held constant and the area is increased? | Pressure decreases. |
| Which conversion factor is used to convert between moles and liters at STP | 22.4 |
| . A sample of helium gas has a volume of 520.0 mL when its pressure is 0.835 atm. If the temperature remains constant, what will the pressure of the gas be when it has a volume of 275.0 mL? | 1.58 |
| You collect 250 mL of argon gas at 33.0°C. What volume will the gas occupy at 57.0°C if the pressure remains constant? | 270 |
| What is the volume of gas at 110.8 kPa and 34°C, if an initial amount of gas was 225 mL at 89.3 kPa and 5°C? Assume constant molar amount? | 200 |
| What volume of gas is present when 8.97 moles of carbon dioxide exists at STP? | 200.9 |
| What is the density of C3H8 gas at 887 mmHg, 650 mL, and 467 K? | 0.085 |
| T/F Intramolecular bonds are weaker than intermolecular bonds | false |
| T/F Molecules and/or atoms in a solid are constantly vibrating | true |
| A gas at constant volume begins with a pressure and temperature of 1.55 atm and 37 degrees Celsius. What is the final temperature if the final pressure is 4.4 atm? | 880k |
| What is another name for London Forces? | dispersion forces |
| T/F The higher the viscosity of a fluid, the faster it will flow. | false |
| T/F. Amorphous solids have repetitive unit cells that create an orderly crystal pattern | false |
| boyles law graph | slowly goes down to zero x=p v=y |
| gay lussac | constant going up from zero at a slant like a / x=p t(k)=y |
| charles law | same thing as gay / x=v and t=y |
