Particle Model
True or False: Particles are always moving
True
what type of energy comes from the sun
radiation
What would heat up faster? water with a specific heat capacity of 1.0 or olive oil that has a specific heat capacity of 0.5?
olive oil- because it has a lower specific heat capacity
what is a conductor? define and give an example
a substance that allows the heat to move through it easily - ex) metal
what colour of jelly bean goes into the garbage?
black (licorice)
True or false: everything is made up of cells
False- everything is made up of PARTICLES (only living things are made up of cells- you'll discuss this in science 8)
what type of energy moves through a metal spoon when stirring soup?
conduction
what is temperature?
the average speed (amount of energy) in the particles of a substance
what is an insulator?
a substance that does not allow the heat to move through the substance easily (ex. plastic or wood)
what part of trail mix goes into the garbage?
cashews
Adding energy to particles will......
Make the particles move faster
what type of energy does a furnace use (blowing hot air around)
convection
what is absolute zero?
the level where all particles would not be able to move (equal to -273.15*C)
why do we use insulation in our homes?
what is Mrs. Buswell's favourite colour?
purple
the forces among gas particles are (stronger or weaker) than the forces found in solid particles.. and why?
weaker- the particles have more energy so the force cannot hold them, plus they are farther apart from each other.
you cannot create or destroy energy, it just changes forms
true or false- temperature and heat are the same thing
you are roasting a marshmallow to make s'mores *because let's be honest, they are delicious!! what type of material should you use to roast your marshmallow?
metal is good for the marshmallow part as it transfers the heat through to the other side well. But you want to be holding onto a non metal part as you don't want to burn your hand!
What is Mrs. Buswell's favourite number? (hint- it's between 1-10)
9
What are the parts of the particle theory/model?
1. everything is made up of particles
2. particles are always moving
3. there are forces between particles
4. adding energy to particles makes them move faster
what is kinetic energy
energy of movement
what is specific heat capacity?
the amount of energy (heat) required to raise the temperature of 1 gram of substance by 1*C
explain how insulation, conduction and radiation are important to our lives and society
answers will vary
what is the best subject in school?
SCIENCE!!!
