Density Measurement and Properties

In this video tutorial, Sarah Dix, a physics teacher at Redham House School, guides students through the process of investigating densities. The tutorial covers the necessary apparatus and steps to measure the density of both solids and liquids. It emphasizes the importance of zeroing the balance, recording measurements accurately, and using the correct units. The video also explains the standard density equation and provides tips for obtaining precise results.

What is the main objective of the core practical discussed in the video?

• To understand the concept of mass

• To explore the properties of liquids

• To investigate the densities of various materials

• To learn about different types of solids

Which of the following is NOT required for measuring the density of a solid?

• Balance

• Measuring cylinder

• Displacement can

• Thermometer

What should you do if the solid floats in the water during the experiment?

• Add more water to the can

• Push it under the water carefully

• Remove the solid and try again

• Use a different solid

How is the density of a solid calculated?

• By adding mass and volume

• By dividing mass by volume

• By multiplying mass and volume

• By dividing volume by mass

What is the first step in measuring the density of a liquid?

• Measure the volume of the liquid

• Zero the balance

• Pour the liquid into a beaker

• Record the temperature of the liquid

Why is it important to zero the balance before measuring the liquid?

• To calibrate the balance

• To check the balance's battery

• To ensure the balance is clean

• To avoid measuring the mass of the beaker

What is the equivalent of one millilitre in cubic centimetres?

• 0.1 cubic centimetres

• 1 cubic centimetre

• 100 cubic centimetres

• 10 cubic centimetres

What should you remember to do after calculating the density of a liquid?

• Heat the liquid

• Add the results to your table

• Pour the liquid back into the container

• Re-zero the balance
