State of Matter
This state of matter has a definite shape and volume.
What is a solid?
This tool is used to measure the mass of an object.
What is a balance?
This property describes how something feels, such as smooth or rough.
What is Texture?
Cup A is 45°F and Cup B is 95°F. Which cup has faster-moving particles?
Cup B
Three objects are the same size. Their masses are shown below:
A student says Object A contains the most matter because all three objects are the same size. Which evidence proves the student is incorrect?
Object B has the greatest mass (43 g), so it contains the most matter. Size does not tell how much matter an object contains.
This state of matter takes the shape of its container but has a definite volume.
What is a liquid?
This tool is used to measure
What is volume?
The amount of space matter takes up.
What is volume?
What generally happens to particle movement when temperature decreases?
The particles move more slowly
A student pours a liquid from Container A into Container B. Before and after pouring, the liquid has a volume of 80 mL, but its shape looks different. What two properties of liquids are demonstrated?
A liquid has no definite shape but has a definite volume.
This state of matter has no definite shape or volume.
What is a gas?
This unit is commonly used to measure the mass of small objects.
What is a gram?
How hot or cold matter is.
What is Temperature?
A graduated cylinder starts at 30 mL. A rock is added and the water rises to 47 mL. What is the volume of the rock?
17 mL.
Student 1: “It is large, blue, and smooth.”
Student 2: “It has a mass of 65 g and a volume of 30 mL.”
Which student used measurable properties, and which student used observable properties? Use evidence to justify your answer.
Student 2 used measurable properties because mass and volume can be measured with tools. Student 1 used observable properties because size, color, and texture can be observed.
This state of matter can flow and takes the shape of its container, but does not have a fixed shape.
What is a liquid?
This tool is used to measure the volume of a liquid.
What is a graduated cylinder?
The amount of matter in an object.
What is Mass?
A student observes an unknown substance. It keeps the same volume but changes its shape when moved to another container. Which two pieces of evidence identify it as a liquid?
It has a definite volume and no definite shape.
A student is given an unknown sample with these properties:
Another student claims the sample could be either a liquid or a gas because both take the shape of their containers.
The claim is incorrect; the sample is a liquid. It has a definite volume, and its particles remain close together. A gas does not have a definite volume and spreads out to fill its container.
This state of matter is made of particles that are packed closely together and vibrate in place.
What is a solid?
This tool is used to measure the temperature of a substance.
What is a thermometer?
A student describes an object as small, smooth, blue, and 8 grams. What term describes all of these characteristics?
What are physical properties?
Three samples have these properties:
A: keeps its shape and volume
B: changes shape but keeps its volume
C: changes shape and spreads out to fill its container
A = Solid, B = Liquid, C = Gas.
Student 1: “It is large, blue, and smooth.”
Student 2: “It has a mass of 65 g and a volume of 30 mL.”
Which student used measurable properties, and which student used observable properties? Use evidence to justify your answer.
Answer: Student 2 used measurable properties because mass and volume can be measured with tools.
Student 1 used observable properties because size, color, and texture can be observed.
