Density and Solubility
This formula is used to calculate density.
What is mass divided by volume?
This property of an object changes when it moves from Earth to the Moon.
What is weight?
This physical property allows iron to be separated from a mixture of sand and salt.
What is magnetism?
A valid experiment must have only one of these variables tested at a time.
What is an independent variable?
An object has a mass of 10 grams and a volume of 2 cubic centimeters. Its density is this.
What is 5 grams per cubic centimeter?
This stays the same even when an object’s weight changes due to gravity.
What is mass?
These properties—such as density, boiling point, and conductivity—do not depend on how much of a sample you have.
What are physical properties?
This part of an experiment is used to compare results and keeps all conditions the same except one.
What is the control?
When an object’s density is greater than the liquid it’s placed in, this happens.
What is it sinks?
The strength of gravity between two objects increases when this property increases.
What is mass?
When a student doubles the amount of a substance, this property remains unchanged.
What is density?
The definition of observation.
What is the act of actively noticing and recording events, phenomena, or data to gather information using one's senses or instruments.
This term describes how well a substance dissolves in a liquid, like salt in water.
What is solubility?
If the mass of one object increases, this happens to the gravitational force between two objects.
What is it increases?
This property tells how easily electricity can flow through a substance.
What is electrical conductivity?
When scientists share their data and procedures so others can perform the same experiment, this process is called this.
What is replication?
If you double the amount of a substance, this property will not change.
What is density?
This force must be overcome by thrust for a rocket to lift off into space.
What is gravity?
This property describes how easily a material lets heat pass through it.
What is thermal conductivity?
The definition of a dependent variable.
What is the variable that is measured?
