Chapter 3 - Particles At Work Flashcards
What is a series circuit
Where components are in a single loop one after the other
What is a parallel circuit
Where components are in separate loops
What is electric current
When charge flows
What is potential difference
The energy transferred between two points in a circuit
What is internal energy
The sum of all kinetic energy
How do you raise internal energy
Increase temp
What is specific heat capacity
Energy required to increase 1kg of substance by 1°c
What are the four atomic structure models
1) Daltons model
2) plum pudding model
3) nuclear model
4) bohrs model
What is Daltons model
Sphere with no protons, neutrons or electrons
What is the plum pudding model
Electrons in cloud of positive gas
What is the nuclear model
Electrons orbit a nucleus
What is a bohrs model
Electrons orbit at different distances called shells
What is alpha particles
Has 2 protons and 2 neutrons
What are beta particles
Have a fastoving electron
What is gamma radiation
