Change of state
2 causes of change of state
temperature, pressure
Name the 3 types
Cubical
Superficial
Name the types
Only cubical
Gases expand ___ than liquids
more
Which material is used in pendulums
Invar
Change in temp
Change in state
Change in size
Factors affecting expansion
Original length/area/volume
temperature
Material
Factors
Original volume
temperature
nature
Which is more dense(matter's three states)
Who will expand more Iron or Invar
Iron
Explain change of state
You better know
Name the coefficients for each
linear=alpha
Superficial=beta
cubical= gamma
Name the coefficient
gamma
Explain expansion in gases through molecular motion
In gases, molecules are more spaced out. On heating the kinetic energy increases and they move more violently in all space available to them for motion. As a result, the inter-molecular separation increases, so they expand
riveting
Exceptionally(fill in the blanks)____(good/bad)
Factors affecting evaporation
Blowing air
Increasing surface area
Heat
Humidity
+800
siu
-- 400
nope , - 400
Bonus(double jeopardy)
Name 6 Greek symbols used in physics
Alpha,beta,gamma,sigma,mew,lambda,omega,delta
Give the ratios of alpha:beta:gamma
1:2:3
Difference between boiling and evaporation (3)
You should know
+1 million
Give an experiment to show liquid expansion
I made you talk for so long, only to get -400
Unless you get it wrong or didn't answer, then no points
Give an experiment to show gaseous expansion
Attach a deflated balloon to the top of a water bottle. Place the bottle in a bowl of water.
After some time you will notice that the balloon has inflated.
