​Mass & Weight

​Remember:

• How to measure mass (scale/TBB)

• Mass= Amount of Matter

• Weight= Amount of gravity on

  an object. Scale is used to measure

Multiple Choice

What statement is true?

• Mass never changes. Weight does.

• Weight never changes. Mass does.

• Both mass and weight change because they are affected by gravity.

• Neither mass nor weight change. They are always the same.

Multiple Choice

Weight is the measure of the force of ______ on an object.

• Density

• Mass

• Matter

• Gravity

• Velocity

Multiple Choice

Mass is the measure of the amount of ________ in an object.

• Density

• Weight

• Matter

• Gravity

• Velocity

Multiple Choice

A space probe lands on a planet that has half the pull of gravity as Earth.

What effect does this have on the space probe’s weight and mass?

• Its weight is reduced to half its weight on Earth, and its mass

  remains the same as on Earth.

• Its weight remains the same as on Earth, and its mass is reduced to

  half its mass on Earth.

• Both its weight and mass are half of what they are on Earth.

• Both its weight and mass remain the same as on Earth.

​Matter CANNOT be created nor deystroyed

Each capital letter represents an element.

• 10 grams

Multiple Choice

Jordan adds some soil and plants to a large glass jar to build a

terrarium. He waters the plants and then adds two snails, two crickets,

and an earthworm to the jar. Jordan then places the lid tightly on the

jar and sets it on a sunny windowsill. Based on the law of conservation

of mass, which of the following is expected to occur inside Jordan’s

terrarium?

• The mass will increase as the plants grow and decrease when the

  snails eat the plants.

• The mass will increase as the earthworm digests the soil.

• The mass will decrease when the crickets die.

• The mass will neither increase nor decrease.

​Remember:

​

• ​Physical Properties: Observed, Measured, and Tested.

• ​Different kinds of physical properties

• Physical Properties: ​Doesn't change the identity of the substance.

Multiple Choice

Students compared the solubility of sodium chloride (NaCl)

and potassium chloride (KCl) in water at different temperatures.

They recorded their results as mass, in grams (g), dissolved in

100 milliliters (mL) of water at different temperatures, in degrees

Celsius (°C), as shown in the graph below.

Which statement best compares the solubility of these substances?

• KCl is more soluble at 20°C than NaCl is.

• Both substances are equally soluble at 30°C.

• KCl will become less soluble at temperatures greater than 40°C.

• Both substances have the same solubility from 20°C through 40°C.

​States of Matter

​Remember:

• The movement of particles

• Arrangement of particles

• shape and volume

Ms. Brooks demonstrated phase changes to her class. She lit a candle

and let the melting wax drop into a beaker of cold water, as shown

below. The temperature of the water was four degrees Celsius (4°C).

Which statement best explains what happened to the wax as it came in

contact with the cold water in the beaker?

• The wax changed from a liquid to a solid as it gave off heat to its

  surroundings.

• The wax changed from a liquid to a solid as it increased in

  temperature.

• The wax remained in the liquid phase as it decreased in temperature.

• The wax remained in the liquid phase as it absorbed heat.
