Determining Density of Solids and Liquids

• What is the first step in determining the density of solids and liquids?

  Use a balance to find mass
• How do you measure the mass of a regular solid?

  Use a balance to find its mass
• What tool is used to measure small dimensions of solids?

  Vernier callipers or a micrometer
• What should you use to measure the volume of a regular solid?

  Calculate volume using relevant formula
• What is the formula for density?

  Density = mass / volume
• What is the unit of density?

  kg/m³
• How do you find the volume of an irregular solid?

  Use a eureka can to find volume
• How do you measure the mass of a liquid?

  Pour liquid into a measuring cylinder on balance
• What should you do after pouring 10 ml of liquid into the measuring cylinder?

  Record mass and total volume
• What should you do after recording the mass and volume of the liquid?

  Repeat until measuring cylinder is full
• How do you calculate the average density from multiple measurements?

  Take an average of calculated densities
• What is the formula for density in terms of mass and volume?

  Density = mass (kg) / volume (m³)
