Grade 8 Discovering Science

Grade 8 Discovering Science. Unit 3 : Fluids and Viscosity. Chapter 7. Viscosity describes a fluid’s resistance to flow. QUESTIONS. Why do some fluids seem to hold their shape longer? Why do some fluids take up more space than other fluids at different t temperatures?

CHAPTER 7 Molecular Geometry, Intermolecular Forces, and Bonding Theories

CHAPTER 7 Molecular Geometry, Intermolecular Forces, and Bonding Theories. Shapes of Molecules and Ions Molecules and ions have a three dimensional shape. This shape can be important in determining the chemical behavior of a substance. We will discuss two types of geometries:

Chapter # 4

Chapter # 4. Basic Concepts of Matter. Matter Defined. Matter is anything that has mass and occupies space. Matter can be invisible. Air is matter, but it cannot be seen. Matter appears to be continuous and unbroken.

FACTORS AFFECTING RATE OF DISSOLVING AND SOLUBILITY

FACTORS AFFECTING RATE OF DISSOLVING AND SOLUBILITY. SECTION 8.2. FACTORS AFFECTING RATE OF SOLUBILITY. TEMPERATURE High temp  more kinetic energy Particles collide with each other This increases their rate of dissolving. FACTORS AFFECTING RATE OF SOLUBILITY. PARTICLE/ MOLECULE SIZE

Fundamentals of Powder Compression

Fundamentals of Powder Compression. attractive forces exist between particles van der Waal’s, H-bonding, electrostatic consider a number of granules in a die to which a force is applied. Compression. consider the force transmitted through the powder bed

HEAT ENERGY and GAS LAWS Part 2

HEAT ENERGY and GAS LAWS Part 2. Heat is a transfer of energy (usually thermal energy) from a body of higher temperature to a body of lower temperature. Thermal energy is the energy associated with the random motion of atoms and molecules. (4.2a). temperature.
