1.8 Kinetic Theory

What unit is a Pascal (Pa) the same as?

• Ncm²

• N/cm²

• N/m²

• Nm²

In kinetic theory what do we assume about collisions of gas particles?

• Elastic

• Inelastic

• Constant

• Electric

Which of the following is true about the relationship between pressure and volume when temperature is kept constant?

• As volume increases, pressure increases at a decreasing rate

• As volume increases, pressure remains unchanged

• As volume increases, pressure increases at an increasing rate

• As volume increases, pressure decreases at a decreasing rate

What happens to pressure when temperature doubles while volume is kept constant?

• Pressure remains the same

• Pressure is halved

• Pressure doubles

• Pressure decreases

What is the relationship between temperature and volume when pressure is kept constant?

• They are inversely proportional

• They are directly proportional

• They are unrelated

• They are directly proportional only at high temperatures

Absolute zero refers to the temperature when what happens?

• particles have no energy

• particles have maximum energy

• particles start to vibrate

• particles collide

How is the absolute scale of temperature measured?

• In degrees Fahrenheit

• In degrees Celsius

• In Kelvin

• In Rankine

What is the formula to convert between Kelvin and Celsius?

• T(K) = θ(°C) + 273

• T(K) = θ(°C) - 273

• T(°C) = θ(K) + 273

• T(°C) = θ(K) - 273

What does the symbol 'c' represent in the specific heat capacity formula?

• Heat energy

• Mass

• Specific heat capacity

• Change in temperature

What is the specific latent heat of fusion?

• Heat energy needed to change 1kg of a substance from a liquid to a gas

• Heat energy needed to change 1kg of a substance from a gas to a liquid

• Heat energy needed to change a substance from a solid to a liquid

• Heat energy needed to change 1kg of a substance from a solid to a liquid
