Study Notes
Basic Concepts of Matter
- Matter is defined as anything that has mass and occupies space.
- The amount of matter in an object is referred to as mass.
- The space that matter occupies is known as volume.
- Density is calculated by dividing mass by volume (Density = Mass/Volume).
- The SI unit for mass is the kilogram (kg).
- The measure of gravity acting on an object is called weight.
Particle Motion and Laws
- Brownian motion describes the random movement of tiny particles in a fluid caused by collisions with atoms and molecules.
- The kinetic model of matter explains that states of matter depend on the kinetic energy (K.E.) and the attractive forces (A.F.) among particles.
- According to the law of definite proportions, chemical reactions result in substances having integer values for their ratios.
States of Matter
- Solids have a fixed volume, fixed shape, and low compressibility; their particles are closely spaced and vibrate in place.
- Liquids possess a fixed volume but take the shape of their container; their particles are less tightly packed compared to solids and can slide past one another.
- Gases have neither a fixed volume nor a fixed shape, and they are highly compressible; the particles are widely spaced and move freely.
- Plasma is a high-energy, ionized state of matter formed at high temperatures, consisting of ions and free electrons.
Properties of Substances
- Physical properties can be observed or measured without changing the substance's chemical composition. Examples include color, melting point, and density.
- Chemical properties describe how a substance interacts with other substances, leading to chemical changes, such as reactivity and flammability.
Types of Substances
- Pure substances can be classified as elements (simple substances) or compounds (combinations of different elements).
- Mixtures are categorized as heterogeneous (different compositions) or homogeneous (uniform composition).
Key Equations and Measurements
- The density of a substance can be calculated with the formula: Density = Mass/Volume.
- For a block of wood with a mass of 560 g and a volume of 710 mL, the density is approximately 0.79 g/mL.
- The volume of a lump of silver with a mass of 48 grams can be derived from its known density of 10.49 g/mL.
- To find the mass of a brick of dry ice with a volume of 1.45 liters and density of 1.561 g/mL, convert liters to mL (1.45 L = 1450 mL) and apply the density formula.
Conservation and Reaction Laws
- The law of conservation of matter states that matter cannot be created or destroyed in a chemical reaction.
- The laws governing chemical reactions indicate that matter is transformed but the total mass remains constant.
True or False Statements
- Matter possesses mass and volume (True).
- Density is mass divided by volume (True).
- The particle model of matter suggests particles are in constant motion (True).
- The law of definite proportions states that chemical reactions always lead to integer values (False; it states that fixed ratios exist).
Impact of Temperature on States of Matter
- Temperature influences the kinetic energy of particles; higher temperature generally increases kinetic energy.
- When K.E. < A.F., matter is in solid form.
- When K.E. ≈ A.F., matter exists as a liquid.
- When K.E. > A.F., matter is in gaseous form.
