molecules and matter -P6

• What is the formula for calculating density?

  Density = Mass / Volume
• How can you rearrange the formula for density to find volume?


  Volume = Mass / Density
• What are the three states of matter?

  Solid, Liquid, Gas
• How do you measure the density of a regular object?


  Using a Top-Pan Balance
• What is the method to find the density of an irregular object?


  Using a Eureka can and measuring cylinder
• What type of error is a zero error with a Top-Pan Balance?


  Systematic error
• What is a random error that can occur when measuring water levels?

  Not measuring from eye level, leading to parallax error
• What is the formula for calculating energy in terms of mass and specific latent heat?


  Energy = Mass x Specific Latent Heat
• What is Einstein's famous equation relating mass and energy?


  E = mc²
• What does the total energy in a system consist of?

  Total energy = Kinetic energy + Potential energy
• What happens to potential energy and kinetic energy during heating?


  Potential energy increases while kinetic energy remains the same
• What happens to potential energy and kinetic energy during cooling?


  Potential energy decreases while kinetic energy remains the same
• What causes gas pressure in a container?


  Particles colliding with the walls of the container
• How is pressure related to temperature for a fixed mass of gas?


  Pressure is directly proportional to temperature
• How is pressure related to volume for a fixed mass of gas at constant temperature?


  Pressure is inversely proportional to volume
• What is the relationship between pressure and volume for a fixed mass of gas at constant temperature?


  Pressure x Volume = Constant
• What are the units of pressure in the context of gas laws?


  Pascals (P)
• What is the unit of volume in the context of gas laws?


  Cubic meters (m³)
