what is heat capacity
an object or material that can transfer energy to other objects
what is energy source
2 ways mechanical energy can be transferred to thermal energy
What is car brakes,bicycle brakes,skidding tires,shoes,rubbing hands
The 4 features of the Particle Model of Matter
What is:
-All substances are made of tiny particles-The particles are always in motion
-The particles always have space in between them
-Adding heat to matter makes the particles move around faster
State that shows the least change when warmed or cooled & state that show the most(answer in that order)
What is solid(least) & gas(most)
The six changes of states
What is sublimation(solid-gas),evaporation,melting condensation,freezing/solidification,vaporization,sublimation(gas-solid)
List the 5 common features of all energy transfer systems
What is waste heat,control systems,transformations,direction of energy transfer,Energy source
4 ways to produce electricity other than solar energy
What is Geothermal,wind,chemical,mechanical
Creator of the first thermometer
Who is Galileo
A substance that is made of only one type of particles
What is a pure substances
why must all wet clothing be removed from someone who fell in water
because evaporative cooling would cause them to have hypothermia
In _______, the warm fluid, itself, moves from place to place, carrying the thermal energy with it. The moving fluid is called a ___________.
Convection,Convection current
List every reason sulfur dioxide is harmful.
Its colourless, odorless, causes dizziness, messes up your mucus membranes
Creator of caloric fluid
Antoine Lavosier
Name each state and an example of each
Solid(pencil,table,etc)liquid(water,etc.)gas(oxygen, etc.)
What are the forms of electromagnetic radiation in order of biggest wavelengths to smallest
Radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, gamma rays, and cosmic rays.
5ml of water(3 degrees) is stirred with 5ml of water(101 degrees) what will be the temp. of the water, after it's well stirred & why
52 degrees because its the average
What is the greenhouse effect and what is global warming
The greenhouse effect is when greenhouse gases are released and rise into the atmosphere and it creates a layer in the ozone which allows sunlight to enter but lets only a bit leave. Global warming is the warming up of the earth
Thermal energy is the _________ of kinetic energy temp. is the ______ ______ of kinetic energy
the total amount, the average amount
Is it better to make electrical lines longer or shorter,why?
Longer, if to short, contraction will snap the cords
What does specific heat capacity depend on
material the object is made of
the different forms of radiant energy share 3 characteristics:
• They behave like waves.
• They can be absorbed and reflected by objects.
• They travel across empty space at the same very high speed: 300 000 km/s.
why are Energuide stickers used
tells the consumer how much electricity, in kwh/year an appliance uses in one year under normal use.
