Density
Liquids or objects with lower density than water
Will float
Anything that has mass and takes up space is called
Matter
increasing the temperature of something (a gain of heat energy) is called
Heating
What changes are caused by Cooling?
Condensation and freezing
What causes Evaporation
Exemplar response: When you have a liquid and add heat to make a gas
Liquids or objects with higher density than water
Will sink
The 3 states of matter are
Solid, Liquid, and Gas
decreasing the temperature of something (a loss of heat energy) is called
Cooling
An ice cube changes its state from a solid to a liquid when the temperature rises above 0 degrees Celsius is called
Melting Point
Describe how freezing occurs.
When you have a liquid and take away heat.
Whether a substance floats or sinks in water is called
Relative Density
Properties of matter that can be observed, measured, or changed without changing the matter itself are called
Physical Properties
3 types of points of water
Melting, Boiling, and Freezing
Water becomes water vapor when the temperature rises to 100 degrees Celsius is called
Boiling Point
Name 3 types of gas
oxygen, air, and steam
What do you use in order to find out if an object will sink or float?.
Water
What are some examples of physical properties?
Size, shape, texture, and color
Process of changing from a liquid to a gas. Example: Water boiling is called
Evaporation
Water changes from a liquid to a solid when it drops below 0 degrees Celsius is called
Freezing Point
the way something feels when you touch it is called
Texture
What does it look like when an object is sinking?
It will go below water
What type of measurement do we use to measure the mass of an object?
Grams
Thermal energy is the same as
Heat
I am gas. Heat was taken away from me. What change have I been through?
Condensation
True or False: size does determine the mass of an object
False
