P1- matter Flashcards
Density=
mass/volume
mass of a proton
1
mass of a neutron
1
mass of an electron
0.0005
charge of an electron
-1
charge of a proton
+1
charge of a neutron
0
how many times smaller is the nuclear radius to the overall atomic radius
100000 times smaller
1ml=
1cm^3
units of density are…
g/cm^3 or kg/m^3
if an object has a higher density than the liquid it’s in it will…
sink
if an object has a lower density than the liquid it’s in it will…
float
what’s the density of water
1g/cm^3
if oils density is 0.8g/cm^3 does it sink or float in water
float- water has a higher density
what is a eureka can also known as
a displacement can
Change in thermal energy=
mass x Specific heat capacity x change in temperature
what is latent heat of fusion
when a change of state is melting or freezing- the energy required to change that state
what is latent heat of vaporisation
when a change of state is condensing or boiling- the energy required to change that state
Pressure x volume=
constant
Thermal energy for change in state=
mass x specific latent heat
pressure due to a column of liquid
height of column x density x gravitational field strength
