Properties of Matter with Nature of Science Questions
Ariel has 2.6 grams of zinc. What volume of the material does she have if zinc has a density of 7.13 g/cm3
0.4 cm3
A 5 g sample of pure gold has a density of 19.3 g/ml. Your friend purchased a gold ring that was made of 25 g of pure gold. What is the density of the ring?
19.3 g/ml
Which of the following best describes a hypothesis in a scientific investigation?
A statement that can be supported or refuted through carefully crafted experimentation
Four pieces of apple were cut so that all were the same mass and shape. The pieces were placed in four different concentrations of sugar water. After 24 hours, the pieces were removed and their masses determined. The graph shown indicates the change in mass of each piece.
An increase in the concentration of sugar solution will result in an increase in the mass of an apple soaked in it for 24 hours
Four pieces of apple were cut so that all were the same mass and shape. The pieces were placed in four different concentrations of sugar water. After 24 hours, the pieces were removed and their masses determined. The graph shown indicates the change in mass of each piece.
As the concentration of the sugar solution increases, the mass change of the apple decreases
When two liquids are poured into a graduated cylinder, two layers form. Liquid A has a volume of 16 ml and a mass of 87 g. Liquid B has a volume of 234 ml and a mass of 100 g. Based on this information which liquid will form the top layer?
Liquid B because it is less dense than liquid A.
From the table, which substance has the smallest density?
Silver
The following two cubes are both made of iron (Fe). The mass of each cube is shown. Compare the thermal conductivity and density of each cube
The thermal conductivity and density of cube A and cube B are the same
Pauline took two small identical containers and filled them with the same amount of water. She dissolved a tablespoon of salt in one of them and placed both containers in a freezer. Pauline then observed them every five minutes until one of them had frozen. What is most likely the dependent variable (outcome variable) in this experiment?
The time it took for the liquids to freeze
The terms mass and weight are often used interchangeably. When you purchase produce from the grocery store, you place your items on a spring scale. What physical property of matter is being measured?
Weight
Which statement BEST describes the relationship between mass and weight?
Weight is dependent on mass and gravity.
Thomas performed an experiment to measure the temperature of water as he heated it on a hotplate. At the end of his experiment, he plotted the results as shown in the graph below.
melting point and boiling point
Weight is proportional to but not equal to mass. In which of the following situations would a person show an increase in weight but not an increase in mass?
Landing on a planet with more gravity.
The state of matter is an example of a physical property. Why is the state of matter considered a physical property, even though a substance may change between a solid, liquid, and gas?
The chemical nature of the substance does not change.
Which of the following is not a part of every scientific investigation?
Using models to understand objects and processes better
