Use Data to Identify Materials Practice Test

According to the data, which material best matches the unknown? Oak wood: brown, 80g, not magnetic, floats, medium hardness. Aluminum: silver, 100g, not magnetic, sinks, hard. Iron: gray, 200g, magnetic, sinks, hard. Cork: tan, 25g, not magnetic, floats, soft. Unknown: brown, 78g, not magnetic, floats, medium hardness.

Using the property data, identify the unknown material by matching all measured properties.

Reference materials:

• Oak wood: brown, 80 g, not magnetic, floats, medium hardness
• Aluminum: silver, 100 g, not magnetic, sinks, hard
• Iron: gray, 200 g, magnetic, sinks, hard
• Cork: tan, 25 g, not magnetic, floats, soft

Unknown material: brown, 78 g, not magnetic, floats, medium hardness.
