density and kenetic energy Flashcards
definition of density
density is the mass per inch volume
equation for density
density = mass/volume
what is density measured in
g/cm³ and kg/m³
what is mass measured in
g and kg
what is volume measured in
cm³ and m³
what is an independent variable
Independent variable – the variable that is altered during a scientific experiment.
what is a Dependent variable
Dependent variable – the variable being tested or measured during a scientific experiment.
what is a Controlled variable
Controlled variable – a variable that is kept the same during a scientific experiment.
what is the relationship between mass and volume of a regular solid
the mass is directly proportional to the volume
gradient = density = mass per unit volume
what happens to the change of state and kinetic theory of melting form solid to liquid
When the solid is heated this gives the particles more energy.
This causes them to Vibrate more and move more energetically
Bonds between atoms become less strong.
Solid turns into liquid.
what happens to the change of state and kinetic theory of boiling form liquid to gas
When a liquid is heated the particles gain even more energy breaking down bonds allowing them to move around freely.
what is kinetic theory
Kinetic theory describes how the particles in Solids, liquids and gases behave. The temperature and state of a material are determined by the Kinetic energy of the particles.
