单元
练习前按清晰顺序掌握本章核心概念。
Connect particle motion and interaction with pressure, temperature, and changes of state. The model should explain the observation.
Temperature is not the same as total thermal energy. Mass, material, and temperature change affect transferred energy.
Thermal energy transfers because of a temperature difference. Identify conduction, convection, or radiation and justify the dominant mechanism.
For “Θερμοκρασία”, 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 “Θερμότητα”, 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 “Θερμική ισορροπία”, 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 “Τήξη και πήξη”, 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 “Εξάτμιση και βρασμός”, 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.

In a safe test about “Θερμοκρασία”, the first condition gives 14 units and the second 11. Which is greater, and what should be kept the same?
The first value is greater by 3 units. A fair test changes only one factor.
Explain “Θερμοκρασία” in your own words and use a picture, objects, a table, or a simple measurement to support it.
A complete explanation connects the correct idea, a clear representation, and a sensible check.
Θερμότητα
八道分层练习，从基础熟练到考试应用。请先独立完成，再查看提示或答案。
Record 9 safe observations about “Θερμοκρασία” without writing a conclusion yet.
An observation is something seen, heard, or measured.
The response needs 9 specific observable or measurable statements, not guesses about cause.
Design a fair test for “Θερμότητα”: what changes, what is measured, and which 3 things stay the same?
Change one factor only.
Full response: one changed factor, one measurable outcome, and 3 controlled conditions.
Measurements are 8, 5, and 13 units. Put them in a table, find the greatest, and the difference from the least.
Use condition and measurement headings.
Greatest 13, least 5, difference 8 units.
Sort examples of “Τήξη και πήξη” into two groups and state the sorting rule.
Each item should clearly match one group.
A full response gives two named groups, at least two examples in each, and an observable sorting rule.
Choose a suitable tool and unit to measure something connected with “Εξάτμιση και βρασμός”.
Decide whether you measure length, time, mass, temperature, or volume.
The quantity, instrument, and unit must match, e.g. time-stopwatch-s or length-ruler-cm.
From data 3, 9, 15, predict the next value and explain the pattern.
Look for the constant change +6.
21; +6.
Write 3 safety rules for a simple activity about “Θερμική διαστολή” and explain the risk each reduces.
Link each rule to a reason.
A full response gives 3 specific rules, each linked to a risk, and requires supervision where appropriate.
Data A=9 and B=14. Write a conclusion, evidence, and one limitation about “Θερμοκρασία”.
Do not claim more than the two values show.
B is 5 greater than A. The values support this, but two measurements alone do not prove a general rule.
Θερμότητα
六道不同作业，从基础到挑战，包含预计用时、提示和答案指南。
Homework 1: Record 5 safe observations about “Θερμοκρασία” without writing a conclusion yet.
An observation is something seen, heard, or measured.
The response needs 5 specific observable or measurable statements, not guesses about cause.
Homework 2: Design a fair test for “Θερμότητα”: what changes, what is measured, and which 4 things stay the same?
Change one factor only.
Full response: one changed factor, one measurable outcome, and 4 controlled conditions.
Homework 3: Measurements are 4, 6, and 10 units. Put them in a table, find the greatest, and the difference from the least.
Use condition and measurement headings.
Greatest 10, least 4, difference 6 units.
Homework 4: Sort examples of “Τήξη και πήξη” into two groups and state the sorting rule.
Each item should clearly match one group.
A full response gives two named groups, at least two examples in each, and an observable sorting rule.
Homework 5: Choose a suitable tool and unit to measure something connected with “Εξάτμιση και βρασμός”.
Decide whether you measure length, time, mass, temperature, or volume.
The quantity, instrument, and unit must match, e.g. time-stopwatch-s or length-ruler-cm.
Homework 6: From data 6, 8, 10, predict the next value and explain the pattern.
Look for the constant change +2.
12; +2.
