Atoms Elements Molecules Compounds Pure Substance Mixture Solution. Atoms Are the smallest particle of an element that still retain the properties of that element. Elements are made of only one type of atom (element) . Aluminum Copper Hydrogen Fluorine.
Pure Substance or Mixture?. Water Pure Soil Mixture Gatorade Mixture Iron Pure. Kinetic Theory. 12/4. Motion. Kinetic theory is all about how particles move Key ideas All matter made of atoms that act like tiny particles The tiny particles are always in motion
Pure Substance vs. Mixtures. Matter can be a “PURE” substance or a “MIXTURE” . Pure Substance Element Compound. Mixture Homogeneous Heterogeneous. Compounds Can be decomposed into simpler substances by chemical changes, always in a definite ratio, Molecules Carbon Dioxide, CO 2
T C = (T F – 32) 5. 9. T F = (T C 9 ) + 32. 5. Not Pure Substance= Mixture. Slide 1. Alpha, = particles with +2 charge Beta, = high speed e - Gamma, = high energy light (no charge). Dr. Ali Bumajdad. m. n =. M.m. Law of constant composition =1.
P = const. v = const. T. s (kJ/kg). Entropy is a thermodynamic property, i.e entropy only depends on the state of the system. Example: given T & P, entropy, S, can be obtained from a thermodynamic table just like v, u, h.
P = const. v = const. T. s (kJ/kg). Entropy of a Pure Substance. Entropy is a thermodynamic property, the value of entropy depends on the state of the system. For example: given T & P, entropy, S, can be obtained from a thermodynamic table just like v, u, h.
