Physical Science Revision Checklist
Everything to revise for BSE Telangana Class 10 Physical Science — Physics and Chemistry chapters with formulas, reactions, and diagrams sorted by exam weight.
Physics — Electricity (High Weight)
High- Ohm's Law: V = IR — define each quantity and unit
- Resistance in series: R_total = R₁ + R₂ + R₃
- Resistance in parallel: 1/R_total = 1/R₁ + 1/R₂ + 1/R₃
- Electric power: P = VI = I²R = V²/R — know all three forms
- Commercial unit of electrical energy: 1 kWh = 3.6 × 10⁶ J
- Circuit diagram symbols: cell, battery, switch, bulb, ammeter, voltmeter, resistor
Physics — Magnetic Effects (High Weight)
High- Magnetic field due to straight wire, circular loop, and solenoid — direction and diagram
- Fleming's Left-Hand Rule: force on current-carrying conductor in magnetic field
- Fleming's Right-Hand Rule: direction of induced current (generator principle)
- Difference between AC and DC — frequency, reversal, uses
- Electric motor principle vs electric generator principle
Physics — Light and Optics
Medium- Laws of reflection and refraction — state and apply
- Mirror formula: 1/v + 1/u = 1/f and magnification m = −v/u
- Lens formula: 1/v − 1/u = 1/f and power P = 1/f (in metres)
- Defects of vision: myopia (concave lens), hypermetropia (convex lens) — ray diagrams
- Dispersion of white light through a prism — VIBGYOR order
Chemistry — Acids, Bases, Salts (High Weight)
High- Properties of acids and bases — reaction with metals, carbonates, indicators
- Neutralisation reaction: acid + base → salt + water (with example equation)
- pH scale: below 7 = acidic, 7 = neutral, above 7 = basic
- Preparation and uses of: baking soda (NaHCO₃), washing soda (Na₂CO₃), bleaching powder
- Common indicators: litmus, phenolphthalein, methyl orange — colour changes in acid/base
Chemistry — Metals, Non-metals, Carbon
High- Physical properties: metals (lustrous, malleable, ductile) vs non-metals
- Reactivity series — Na, Mg, Al, Zn, Fe, Pb, H, Cu, Ag, Au — order and significance
- Extraction of metals: reduction of oxides, thermite reaction, electrolytic refining
- Alloys: steel, brass, bronze, amalgam — components and uses
- Carbon: covalent bonding, allotropes (diamond, graphite, fullerene) — properties
Chemistry — Periodic Table
Medium- Groups and periods — horizontal rows and vertical columns
- Periodic trends: atomic radius decreases left → right; increases top → bottom
- Periodic trends: electronegativity increases left → right; decreases top → bottom
- Properties of group 1 (alkali metals) and group 17 (halogens)
- Döbereiner's triads and Mendeleev's periodic law vs modern periodic law
