States of matter
The particles move slowly past each other. It has a definite volume but not shape.
What is a liquid?
removing heat from a liquid
What is a solid?
Anything that has mass and takes up space
What is matter?
adding heat to matter
What is expansion?
Particles vibrate in place. Has definite shape and volume.
What is a solid?
adding heat to a liquid
What is a gas?
matter cannot be created or destroyed
what is conservation of mass
taking energy and heat away from matter
What is contraction?
The particles are very excited and are bouncing everywhere. Has no definite volume or shape.
What is a gas?
gas losing heat
What is a liquid?
water turns into solid at this temperature
what is 0?
particles are always doing this
when water freezes
what is expand?
The scientific word to describes anything that has mass and volume.
What is matter?
how states of matter change
what is heating and cooling
attractive forces gets weaker, particles move faster, more space is required between particles
what is heating?
when it's hot, the liquid in a thermometer does this
what is expand?
when vinegar and baking soda mix
what is gas?
particles move faster
what is adding heat?
when the attractive forces in liquid gets stronger
What is freezing?
this materials is denser in its liquid form than its solid form
what is water?
expansion and contraction of concrete and water causes this on roads
what are pot holes?
