Density and my mental breakdown Flashcards
How do you calculate density
Density= mass(kg)/ volume(m3)
How do you get a substance to change state
You add energy
What does energy increase
The vibrations of the atoms
What is heat
The thermal energy contained in an object
What is temperature
A measure of how hot or cold something is
What increases when energy’s transferred
It’s temperature
What does a high SHC mean in terms of temperature
A material needs more heat in order to increase its temperature by 1*c
What does a high SHC mean in terms of energy
It retains the heat energy for longer
Will a substance in the solid state have more or less energy than liquid and why
Yes because the molecules are held tightly together, creating a stronger hold and making it solid
Where is the specific latent heat of vapourisation and fusion
Between liquid and gas and between solid and liquid
What is SLH
The amount of energy required per kilogram of a substance to change its state
What is internal energy
The total KE and potential energy of all particals
What is the equation for pressure
Pressure(n/m2)= force(N)/area(m2)
What will happen if the force is applied to a late area
The pressure will be decreased
Why is the air pressure lower when you’re higher up
There are less air particles and the air is less dense
