Beginning of the Year Chemistry

• What is Matter?

  
  

• Matter is an Element

• Matter is anything that has mass and occupies space

• Matter is anything that costs money

• Matter is anything that has to do with chemistry

What is a mixture?

• A substance made by combining two or more different materials with no chemical reaction
• A substance made by combining two or more different materials with a chemical reaction
• A single substance that cannot be separated into any other kinds of matter
• A substance made by combining two or more different materials with a physical reaction

Answer explanation

Think about identities of the substance(s)

• Which are the three (main) states of matter?

  
  

• Elements, molecules and atoms.

• Solid, liquid and gas

• Iron, water and oxygen.

• Protons, neurons and electrons.

If you fill a glass to the brim with ice water and the ice melts, what will happen?

• • The glass will over flow as the ice turns to water.

• The level of water in the glass will remain unchanged as the ice melts.

• • The water level will drop slightly as the ice melts.

• I'll never find out because I'll drink the water or walk away before anything happens.

Answer explanation

One interesting property of water is that it achieves maximum density as a liquid, not as a solid. So, ice is less dense than water and floats. When it melts, it becomes more dense. More mass per unit volume means the level of the liquid drops slightly.

•  

  What are Atoms ?(more than one answer can be correct)

• Atoms are particles that join up to form molecules which make up molecules.

• Atoms are the substances that are n the periodic table of elements.

• With the help of atoms, molecules are made and elements are formed.

• Atoms are the simplest "building blocks" of matter.

• What are atoms made up of?

  
  

• Protons and neutrons

• Protons and electrons.

• Neutrons and electrons.

• Protons, neutrons and electrons.

• Elements and molecules.

What are elements?

• Elements are water,earth,fire and air.

• Elements are different types of atoms

• Elements are little robots that can dance.

• Protons and Neutrons

What is the Periodic Table?

• A chart of all chemical elements
• A table used for states of matter

• A table for calculations regarding weight

• A table used to predict conductivity
