1. Phase Change
1.1. 4 Phase Changes
1.1.1. ◾Deff; matter change from 1 form or state 2 another <— + heat or remove - substance
1.2. 1️⃣Freezing
1.2.1. remove heat- liquid substan-> liquid 2 Solid
1.2.1.1. freezing point= ℉ - liqu 2 solid
1.3. 2️⃣Melting
1.4. 3️⃣Condenstation
1.4.1. remove heat -> gas 2 liquid
1.4.1.1. condest-point= ℉ gas condense 2 liqui
1.5. 4️⃣Evaporation
1.5.1. + heat 2 liquid -> gas
1.5.1.1. boiling point= ℉ liquid 2 gas
1.6. Sublimation & Deposition
1.6.1. Sublimation
1.6.1.1. solid direct-> gas: e.g.,dry ice
1.6.2. Deposition
1.6.2.1. gas direct solid->water vapor
1.7. Heating &Cooling
1.7.1. Heat= transf-thermal energy - substan
1.7.1.1. + themal energy-> substance= heating
1.7.2. Cooling=remove-themal energy
1.7.3. + heat-Solid->liquid->gas
1.7.3.1. boiling&condense point-->= ℉
1.7.4. cool-> gas->liquid->solid
1.7.4.1. freezing&meltin point --> = ℉
2. Def- matter
2.1. everythi take up space&mass
2.1.1. mass? amt-stuff in obj or sbustance
2.2. ✅ matter <--- tiny particles= atoms
2.3. ✅ Atoms? basic building blocks- matter
2.3.1. 3 types of atoms; protons,neutrons,electrons
2.3.2. diff atoms & combunation atom -> diff materials & substance
2.4. ✅ Energy is matter? No- b/c no mass& Vol.
2.4.1. e.g, heat,light, electricity &sound -not matter
3. States of Matter; matter forms
3.1. ◾3 maj stat matter- depend on particle pack toge-tight,loose, very loose
3.2. Solid
3.2.1. 🔹atom-tight packed
3.2.2. 🔹atom-not move vs vibrate
3.2.2.1. e.g.,ice, pencil, etc.
3.2.3. 🔹define shape &Vol. i.e. keep own shape&Vol.
3.3. Liquid
3.3.1. atom-loose packed
3.3.1.1. atom slightly move
3.3.1.1.1. e.g,water,alchol
3.3.2. definine Vol. vs not define shape
3.3.2.1. shape- depend containier
3.4. Gas
3.4.1. atom-very loose packed
3.4.1.1. continue- move
3.4.2. not Vol.-shape
3.4.2.1. take shape&Vol. - own container
3.4.2.1.1. e.g, water vapor, oxygen
3.5. Plasma
3.5.1. ✅4th sate-matter
3.5.1.1. common-Unieverse vs not com-Earth
3.5.2. gas-heat w/ high temper're.-> ➖ torn off - aroms-> plasma= mass <--- + atom & ➖ atoms)
3.5.3. ✅Where it found?- space between planet,solar system& galaxie
3.5.3.1. e.g., stats, Sun
3.5.4. ✅Natural plasma; Lightening
3.5.4.1. Gas-<--- heat -> plasma
3.5.5. ✅man-made plasma- w/ eletric
3.5.5.1. e.g, fluorscent light- >elect- pass neon gas : neon gas-> plasma
4. 2 Properties Matter? speci-chracter- matter
4.1. Physical
4.1.1. qualtative= obser- w/ sense
4.1.1.1. e.g.color,odor,taste,sound,hardness,flexibility
4.1.2. Qualtative measure
4.1.2.1. e.g.mass,size,shape,density,temperature, magnetism,conductivity,solubility,viscosity, melting point, boiling point
4.2. Chemical
4.2.1. all chemical - intensive
4.2.1.1. e.g.,color,odor,sound,taste,density,viscosity, magnetism
4.2.2. extensive
4.2.2.1. mass,size,vol.,shape
4.2.3. chemical proper
4.2.3.1. reactivity,corrosion,toxicity,flammability,radioactivity
5. change matter
5.1. Physical
5.2. chemical
6. conservation mass
6.1. sum-mass X change
6.1.1. law conserva- i.e. matter-rearrange-change ---> ❌ create,destory
