States of Matter
This state has a definite shape and a definite volume.
What is a solid?
This change turns ice into liquid water and happens when ice absorbs heat.
What is melting?
This energy from the Sun gives Earth light and warmth.
What is solar energy?
This reddish-brown substance forms on iron over time
What is rust?
What do we call it when a substance "disappears" into another? EX: Mixing sugar and water
What is dissolving?
This state takes the shape of its container and has a definite volume.
What is a liquid
This change turns liquid water into water vapor as it absorbs energy.
What is evaporation?
This energy comes from electric charges and powers lights and computers.
What is electrical energy?
Name two signs of a chemical change.
What is Bubbles, color change, temp change, sound, smell
Ice with a mass of 50 g melts in a closed container. What is the mass of the melted ice? Less than 50g, more than 50g, or equal to 50 g.
This state spreads out to fill its container because its particles move freely and are the farthest apart.
What is a gas
This change forms droplets on a cold glass when gas loses energy.
What is condensation?
This energy comes from moving air and can turn a turbine.
What is wind energy?
Wood burning makes ash and gases and gives off heat and light. This kind of change forms new substances.
What is a chemical change?
A reaction makes gas in a sealed container. What law explains why the mass stays the same?
What is conservation of mass?
A balloon can be squeezed because particles in this state have lots of empty space between them.
What is a gas?
What happens to an object's particles when it is heated?
What is the particles move faster
This energy is related to how quickly particles move and helps tell how hot or cold something is.
What is thermal energy?
Boiling water makes bubbles, but the bubbles are water vapor. This kind of change is happening.
What is a physical change?
What were the three powders we tested in science Lab with Mr. Gugel?
Baking soda, baking powder, cream of tartar
Juice is poured from a bottle into a cup. Its shape changes, but this stays the same.
What is its volume?
A sealed bag of ice sits on a sunny windowsill. Sun energy moves into the ice; later, droplets form inside. Name the two phase changes, in order.
What are melting and condensation?
A wind turbine changes the energy of moving air into this kind of energy.
What is electrical energy?
Two clear liquids mix and form a white solid. This is evidence that a new substance is formed. What kind of change happened?
What is a chemical change?
A student mixes vinegar and baking soda in an open cup, and the mass afterward is lower. The student says the matter was destroyed. Tell where the missing mass went.
What is the gas created escaped into the air?
