Physics 1 Flashcards
What is the process called if a solid is turned into a liquid
The process called if a solid is turned into a liquid is called MELTING
What is the process called if a solid is turned into a gas
The process if a solid is turned into a liquid is called SUBLIMATION
What is a description of Specific Heat Capacity (SHC)
The specific heat capacity is the amount of energy needed to raise the temperature of 1kg of the substance by 1 degree celcius
What is energy measured in
Energy is measured in Joules or Kilojoules
What is the process called if energy is added to a substance but the temperature stays the same
Latent heat of fusion or Latent heat of vaporisation
How do you calculate pressure
PRESSURE=FORCE/AREA
How can you increase the pressure of an object containing gas
INJECTING MORE GAS (PARTICLES) OR TO INCREASE THE HEAT OF THE CONTAINER
What does Pressure*volume equal
CONSTANT
If the energy is 200000 Joules how many kilojules is the energy
200kj
In which are the particles closer together Gas or a liquid
LIQUID
Why does an gas/liquid/solid lose temperature
By the particles losing energy
Are particles soft or hard
HARD
Can particles be squashed
NO
Can particles be stretched
NO
Does the sizes of particles differ from object to object
YES there are different types of particles
What is the process called if you are turning a gas to a liquid
The process called if you are turning an gas to a liquid is called CONDENSING
(CONDENSATION)
Which unit is used to measure mass
KG (Kilograms)
What does DESSU stand for
D=Data
E=Equation
S=Substitude
S=Solve
U=Unit
Can energy be destroyed
No just moved
What is the equation for speed
Speed=Distance/Time
What are the strong forces of attraction called
The strong forces of attraction are called BONDS
Does particles move fast
Particles move very fast
What is the equation for Density
Density=Mass(Kg)/Volume( 3
M)
What is needed to break bonds
ENERGY is needed to break bonds
What is the Specific Heat Capacity of ICE
The Specific Heat Capacity of ICE is 2100
What is the Specific Heat Capacity of Water
The Specific Heat Capacity of Water is 4200
If a solid has a mass of 2000kg what is the mass of the liquid if the solid melts going to be
The mass of the melted solid (liquid) will be the same (2000kg)
If a container is containing a gas of 200 degrees celcius is opened and exposed to a surrounding of -20degrees celcius will heat escape or cold air mix with the hot air in the container causing an lower temperature
The heat will escape from the container
What is the stage where Ice is turned into Water called in terms of latent heat
The answer would be The Specific Latent Heat of Fusion
What is the stage where Water is turned into Steam called in terms of latent heat
The answer would be The Specific Latent Heat of Vapourisation
Is the gravitational energy changed when picking up a ball and putting it on a shelf
Yes it decreases
What is the gravitonal energy changing to an object
The gravitational energy is how much the object is affected by gravity
what is the process called when a gas is turned into a solid
This process is called DEPOSTION
If SHC=ΔE What is ΔE equal to
__
m*ΔT
ΔE=mSHCΔT
Which is the particles closer together solid gas or liquid name in order
Solid liquid then gas
