Solid, Liquid, Gas / Density Flashcards
(30 cards)
What is formular for density
Density = mass/ volume
What are the three state of matter
Solid, liquid, gas
Which state of matter have the highest energy
Gas
Which state of matter is the most dense
Solid
Which state of matter is in a regular structure
Solid
Which state of matter is where particle slide past each other
Liquid
Which state of matter has the strongest bond between particle
Solid
Describe the movement of gas particle
Move freely in all direction randomly
Usually far apart
What is the process from solid to liquid
Freezing
What is the process from liquid to solid
freezing
What is the process from liquid to gas
Evaporation/boiling
What is the process from gas to liquid
Condensation
What is the process from solid to gas
Sublimation
What is the difference between evaporation and boiling
Evaporation will occur below the boiling point
as it is only the most energetic particle will break their bond and escape
Describe how a solid changes into a liquid when it is heated
-Increased in temperature
-Allow the particle to vibrate faster
-KE will increase
-Break the bonds and changes state
What is actually temperature
The average energy of the particle
Will a more dense object sink or float in a less dense object
It will sink.
e.g an apple in water
What happens to the volume as temperature increase
It will increase as it will expand
What happens to the density as temperature increase
It will decrease as volume will increase with the same mass
What is the definition of Density
The amount of mass in a specific volume
What is 1 kg/m^3 to g/cm^3
1 kg/m^3 = 0.001 g/cm^3
How to measure the density of a regular cube
-Measure the length, width, height using a ruler
-Calculate volume using
-v= l x w x h
-Zero a scale and read the mass
-Determined density by density=m/v
How to measure the density of an irregular solid (using eureka can)
-Fill the eureka can will water so that water stop dripping out of the spout
-Put a measuring cylinder below the spout
-Place object into can and measure the displaced water in the cylinder
-Zero a scale and read the mass
-Determined density by density=m/v
How to measure the density of an irregular solid (using measuring cylinder)
-Fill a measuring cylinder to a known value and note the volume
-Place the object inside the cylinder and read off new water level
-The volume is new water level-the known value
-Zero a scale and read the mass
-Determined density by density=m/v
