The States of Matter
This term describes anything that has mass and takes up space.
What is matter?
____________ is made of particles.
What is everything?
When matter changes state it can be reversed by either adding or removing this.
What is heat?
This occurs when any state of matter is heated.
What is expansion?
A widely used construction material that begins expanding at 20 degrees Celsius.
What is steel?
This state can be described as having a definite shape and volume.
What is a solid?
Matter can be classified according to these.
What are physical characteristics?
The process of a solid turning to a liquid.
What is melting?
This state of matter has the smallest expansion and contraction that occurs.
What is the solid state of matter?
A building material that is relatively resistant to heat, as it begins expanding at 35 degrees Celsius.
What is concrete?
This state of matter can be described as having a definite volume, but they will take the shape of the container they are in.
What is liquid?
What are spaces?
The process of a liquid turning to a gas.
What is evaporation?
Thermometers are able to show the increase of temperature using this process.
What is thermal expansion?
A building material that's expansion depends on its orientation, and begins at 30 degrees Celsius.
What is wood?
The atoms in this state of matter move freely, in a random order.
What is a gas?
This affects the speed at which particles move.
What is temperature?
The process of a gas changing state to a solid.
What is deposition?
A basketball being deflated after being left outside in the winter is an example of this.
What is thermal contraction of a gas?
A common building material for roads, and it's expansion begins at 50 degrees Celsius.
What is asphalt?
This principle explains that when a change of state occurs, the volume will remain the same.
What is the Principle of Conservation of Mass?
Particles are always moving because they have this type of energy.
What is kinetic energy?
Dry ice vaporizing at room temperature is an example of this.
What is sublimation?
Gaps are left in railway tracks and sidewalks for this reason.
The building material that begins expanding at 15 degrees Celsius, making it unfavourable for hot climates?
What is aluminum?
