Ключевые идеи главы в понятной последовательности перед практикой.
Modern physics uses models tested by spectra, scattering, decays, and detectors. Distinguish an observation from its interpretation.
A single nuclear decay is random, but large samples follow predictable laws. Use half-life or an exponential relation with the correct scale.
In atomic and nuclear processes, check energy, momentum, charge, and particle numbers where applicable. Do not mix eV and J without conversion.
For “Thermal energy transfers”, start from an observation or model, define quantities and units where relevant, and separate the changed factor from the measured outcome. Support the conclusion with data and state the test's limitations.
For “Temperature and internal energy”, start from an observation or model, define quantities and units where relevant, and separate the changed factor from the measured outcome. Support the conclusion with data and state the test's limitations.
For “Gas laws”, start from an observation or model, define quantities and units where relevant, and separate the changed factor from the measured outcome. Support the conclusion with data and state the test's limitations.
For “Thermodynamics in HL scope”, start from an observation or model, define quantities and units where relevant, and separate the changed factor from the measured outcome. Support the conclusion with data and state the test's limitations.
For “Particle models”, start from an observation or model, define quantities and units where relevant, and separate the changed factor from the measured outcome. Support the conclusion with data and state the test's limitations.

Следуйте методу шаг за шагом и проверяйте обоснование каждого шага.
A sample starts with 640 active nuclei and 4 half-lives pass. How many are expected?
N = 40
Before calculating, explain the key idea from “Thermal energy transfers” and which conditions must be checked.
The answer should show not only which rule is used for “Thermal energy transfers”, but also why it is valid here.
Theme B: Particulate nature of matter
Восемь заданий от базовых навыков до экзаменационного уровня. Сначала решите самостоятельно.
A sample starts with 144 nuclei. How many are expected after three half-lives?
Halve three times.
18.
Structure a solution for “Temperature and internal energy”: givens, SI units, law, substitution, and interpretation.
State the law before substituting numbers.
A full solution states symbols/units, selects a valid law for “Temperature and internal energy”, shows substitution and calculation, and interprets the result.
Identify three uncertainty sources in measuring “Gas laws” and improve each one.
Consider instrument resolution, reaction time, repeats, and controls.
A full response links each specific error source to a targeted improvement and identifies random or systematic impact.
Plan a suitable graph for “Thermodynamics in HL scope” data and explain how to obtain a gradient or relationship.
Put the independent variable on x and dependent variable on y.
A full response labels axes/units, uses a suitable scale and best fit; gradient uses a large triangle and is interpreted with units.
Check whether a result for “Particle models” is sensible using units, order of magnitude, and a limiting case.
A check should not merely repeat the same calculation.
A full check confirms dimensions/units, compares expected magnitude, and tests behaviour when one variable becomes very small or large.
Connect “Thermal energy transfers” to energy conservation or a force/field model and justify the choice.
Define the system and interactions.
A full response defines the system, describes transfer or interaction, applies the appropriate model, and states losses or limitations.
Write a multi-step exam response about “Temperature and internal energy” with calculation and evaluation.
Separate givens, model, calculation, result, and evaluation.
A full response includes an appropriate diagram/model, laws, algebraic rearrangement, SI substitution, suitably precise result, and evaluation of assumptions.
Compare two methods for investigating “Gas laws” and select the more reliable using criteria.
Use accuracy, repeatability, control, and safety.
The choice must use at least three comparable criteria and acknowledge one trade-off or limitation.
