AQA A Level Materials Quiz

What is density?

• The volume per unit mass of a substance

• The mass per unit volume of a substance

• The amount of space occupied by a substance

• The weight of a substance per unit volume

What happens to the mass and volume of materials when they are combined to form an alloy?

• The mass and volume both increase

• The mass and volume both decrease

• The mass and volume do not change

• The mass increases and the volume decreases

When creating an alloy, how are metal A and metal B combined?

• In equal ratios

• In slightly different ratios

• Metal A is doubled compared to metal B

• Metal B is doubled compared to metal A

What is V referred to in the context of the density of an alloy?

• The velocity of the mixture

• The viscosity of the mixture

• The volume of the mixture

• The variety of metals used

What is the first step in determining the density of a regular solid?

• Measure the length, width, and height using a ruler

• Calculate the volume using length x width x height

• Find the mass of the object using a balance

• Calculate the density using a formula

How do you calculate the volume of a regular solid?

• Mass divided by density

• Length plus width plus height

• Length x width x height

• Mass times the acceleration due to gravity

Which instrument is used to measure the length, width, and height of a regular solid?

• A balance

• A ruler

• A protractor

• A pipette

What is the first step in finding the density of an irregular solid using the method shown?

• Place the object in the measuring cylinder

• Record the volume of the water

• Find the mass of the object using a balance

• Calculate the density

After finding the mass of the object, what should you do next according to the method provided?

• Calculate the density

• Record the new volume of the water + the object

• Add some water to a measuring cylinder

• Work out the volume of the object

How do you determine the volume of the irregular solid using the method described?

• Measure the dimensions of the object with a ruler

• Use the water displacement method by recording the new volume of water after placing the object in the cylinder

• Fill the measuring cylinder to the brim and then place the object inside

• Weigh the object in water
