Describing and Classifying Matter
Color, shape and boiling point are all examples of this type of property
What are physical properties?
mass divided by volume
What is density
Rusting or oxidation is this type of change.
What is a chemical change?
In general, as the temperature _________ a substance becomes more dense.
What is decreases?
True or false: the temperature of water will increase while it boils
What is false?
Crushing a can is this type of property.
When dish soap (2 g/mL) and corn oil (1.5 g/mL) are mixed, this is the one that will rise to the top.
What is corn oil?
Cooking, grilling and baking are all types of this change.
What are chemical changes?
Particles are spread slightly apart and flowing over each other.
What is a liquid?
Changing from a solid directly to a gas
What is sublimation?
Methane (chemical formula is CH4) contains this many elements.
What are 2 (carbon and hydrogen)?
When honey (1.25 g/mL) and water (1 g/mL) are mixed, this one will sink.
What is honey?
Softening butter, folding aluminum foil and cutting an apple are all types of this change.
What are physical changes?
What is gas?
Condensation point is equal to the...
What is evaporation point?
Anything that has mass and takes up space.
What is matter?
If 5mL of a substance has a mass of 15g, this is its density.
What is 3 g/mL?
Matter cannot be created or destroyed is this law
What is the law of conservation of mass?
Liquids that move more slowly and are thicker have higher this.
What is viscosity?
The main cause of any change of state.
What is a change (increase/decrease) of thermal energy?
H2O= element? compound? or mixture?
What is a compound?
If you know the density and volume of an object, this is how you find the mass.
What is density times volume?
No matter where you are, ______ stays the same, but _______ is affected by gravity
What are mass and weight?
Particles are fixed and vibrate in place.
What is a solid?
Higher gas pressure above a liquid will require the thermal energy to be this, in order for the liquid to change to a gas.
What is a greater thermal energy is required?
