21 Questions
What is the smallest particle of an element that can enter into a chemical combination?
Atom
What is the definition of matter, and what are the three states of matter commonly found on earth?
Matter is anything that occupies space and has mass. The three states of matter commonly found on earth are solids, liquids, and gases.
Explain the difference between weight and mass.
Mass is a measure of the amount of matter in an object, while weight is the force that gravity exerts on an object.
What is the fourth state of matter, and where does it occur naturally?
The fourth state of matter is plasma, and it occurs naturally in the interiors of stars.
Describe the fourth state of matter and where it occurs naturally.
The fourth state of matter is plasma, which occurs naturally in the interiors of stars.
Who supported the hypothesis that matter is composed of atoms with quantitative measurements in the early nineteenth century?
John Dalton
Which elements consist of a collection of individual atoms that move about independently of one another?
Helium, neon, argon
Explain the law of conservation of matter.
The law of conservation of matter states that there is no detectable change in the total quantity of matter present when matter converts from one type to another or changes among solid, liquid, or gaseous states.
Can matter have properties of more than one state at the same time? Provide an example.
Yes, some samples of matter can have properties of solids, liquids, and/or gases at the same time. An example of this is a mixture.
What is the difference between mass and weight?
The mass of an object is a measure of the amount of matter in it, while weight refers to the force that gravity exerts on an object.
Give an example of how the law of conservation of matter applies in the real world.
Brewing beer and the operation of batteries provide examples of the conservation of matter.
What are units composed of pairs of atoms, or molecules, joined by strong forces called chemical bonds?
Compounds
What is the law of conservation of matter, and provide an example.
The law of conservation of matter states that there is no detectable change in the total quantity of matter present when matter converts from one type to another or changes among solid, liquid, or gaseous states. An example of this is brewing beer and the operation of batteries.
Can matter have properties of more than one state? Explain.
Yes, matter can have properties of more than one state when it is a mixture.
What is a molecule?
A unit composed of pairs of atoms or molecules joined by strong forces called chemical bonds
What unique properties do plasmas have that justify their classification as a state of matter distinct from gases?
The presence of charged particles imparts unique properties to plasmas that justify their classification as a state of matter distinct from gases.
What are examples of elements?
Iron, silver, gold, aluminum, sulfur, oxygen, copper
How do plasmas differ from gases, and what imparts unique properties to plasmas?
Plasmas differ from gases in that they have charged particles. The presence of charged particles imparts unique properties to plasmas that justify their classification as a state of matter distinct from gases.
What is an example of a pure substance that has the same physical properties regardless of the source from which it is isolated?
Sucrose (table sugar
Can you give an example of matter converting from one type to another, while following the law of conservation of matter?
Yes, an example of this is when water freezes into ice or when ice melts into water. The total quantity of matter remains the same, only the state of matter changes.
What are the three states of matter commonly found on earth?
The three states of matter commonly found on earth are solids, liquids, and gases.
