Properties of Matter/ Density

A rocket ship is in space headed toward Earth. Once it safely lands on Earth, how will its mass and weight be affected?

• Mass will increase; weight will stay the same

• Mass will stay the same; weight will increase

• Mass will decrease; weight will stay the same

• Mass will stay the same; weight will decrease.

The diagram shows a hammer with a mass of 20 g being dropped in a graduated cylinder. What is the density of the hammer?

• 2 g/mL

• 3 g/mL

• 4 g/mL

• 5 g/mL

Block A has a density of 3.5 g/mL. Block B, has a mass of 5 g and a volume of 10mL. Both blocks were placed in a beaker of water. What statement explains what will happen to the blocks placed in water? (Density of water = 1 g/mL)

• Block A will sink in the water, Block B will float in water.

• Block B will sink in the water, Block A will float in water.

• Block A and Block B will float in water.

• Block A and Block B will sink in water.

Jenny is researching the metal gold. Google tells her that 50 g of gold has a melting point of 400 degrees Celsius and is a good conductor. Jenny wants to test this herself, so she tests the melting point and conductivity on a 25 g piece of gold. What will the melting point and conductivity be for her sample?

• Jenny's results will be twice as much as Google’s results

• Jenny's results will be half as much as Google’s amount

• Jenny's results will be the same as Google’s amount

• Jenny's results will be slightly lower than Google’s amount

True or False: A thermal Conductor is a material that allows heat to conduct (transfer) through it meaning it can get hot. A thermal insulator is a material that does not allow heat to transfer through it meaning it will remain cool.

• True

• False
