MATTER - PROPERTIES AND TRANSFORMATION: Principles Of Chemistry - Gaseous State
What is the unit for temperature that must be used in gas law calculations (Boyle's, Charles', Combined)?
Degrees Celsius (°C).
Any of the above.
Degrees Fahrenheit (°F).
Kelvin (K).
Boyle's Law states that for a fixed mass of gas at constant temperature, the pressure is:
Directly proportional to its volume.
Independent of its volume.
Inversely proportional to its volume.
Directly proportional to its temperature.
Which of the following explains why solids have a definite shape and volume?
Particles are closely packed and can slide past each other.
Particles are far apart and move randomly.
Particles have very high kinetic energy.
Particles are tightly packed in fixed positions, vibrating about their mean positions.
Charles' Law states that for a fixed mass of gas at constant pressure, the volume is:
Directly proportional to its absolute temperature (in Kelvin).
Inversely proportional to its temperature (in Celsius).
Independent of its temperature.
Directly proportional to its temperature (in Celsius).
The process of 'sublimation' is when a substance changes directly from:
Solid to gas.
Liquid to gas.
Gas to liquid.
Solid to liquid.
