P6 Particles & Matter Flashcards
What is density?
Density is how closely packed the particles are in a solid, liquid gas.
How do you find density?
Mass/volume
What are the units for density?
Kg/m^3
What are the units for mass?
Kilogram (Kg)
What are the units for volume?
m^3
What is volume?
Volume refers to how much space there is in a 3D object.
What is Archimedes Principle?
A body at rest in a fluid is acted upon by a force pushing upward called the buoyant force, which is equal to the weight of the fluid that the body displaces.
What is Latent Heat of Fusion?
Specific Latent Heat of Fusion refers to the energy supplied to change 1Kg of a substance from solid state to liquid state.
What is latent heat?
The energy transferred to a substance when it changes state.
What is Latent Heat of Vaporisation?
Specific Latent Heat of Vaporisation refers to the energy suppliednto change 1Kg of a substance from liquid state to gaseous state.
What is internal energy?
The Internal Energy of a substance is the combined energy of the kinetic and potential energy of the particles in the substance (or system).
What 2 energy stores are used in Internal Energy?
Kinetic Energy
Potential Energy
How do you find the constant?
Pressure X Volume
What are the units for pressure?
Pascal(Pa)
What is Boyle’s Law?
Boyle’s Law states that for a fixed amount of (ideal) gas at a fixed temperature pressure is inversely proportional to the volume.
