What is inside this Science unit test
This is the UT1 Science (2025) paper. It is a 20-mark test split into two sections of 10 marks each. The paper covers Physics and Chemistry topics from the Class 10 syllabus.
Section A focuses on Physics. It tests concepts like work, power, and energy. You will find true or false questions on horsepower and potential energy. The section also asks you to differentiate between work and power.
Section B focuses on Chemistry. It covers acids, bases, and salts. You must give examples of a weak mineral acid, an acid salt, and an efflorescent substance. The section also asks you to define a normal salt and an alkali with examples.
How to use this paper for exam preparation
Use this unit test as a timed practice run. Sit down with a pen and paper and attempt the full paper without looking at your textbook. This builds the habit of recalling answers under pressure.
- Attempt Section A first to secure the Physics marks before moving to Chemistry.
- Review the true or false statements carefully. If a statement is false, write down the correct fact beside it.
- Check your numerical working for the work and power question. Ensure you convert units like centimetres to metres before calculating.
- Verify your Chemistry examples. A weak mineral acid example must be a mineral acid that does not fully ionise.
After finishing the test, check your answers against your textbook or class notes. You can find more reading material on our Class 10 books page. For official syllabus updates, always refer to the CISCE official website.
Worked example: calculating work and power
The paper asks a boy weighing 350 N to climb 30 steps, each 20 cm high, in 1 minute. You must calculate the work done and the power. Here is the step-by-step method.
First, find the total vertical height. Each step is 20 cm, which is 0.2 metres. For 30 steps, the total height is 30 times 0.2 m, which equals 6 m.
Next, calculate the work done. The formula is Work = Force times Displacement. Here, the force is the boy’s weight (350 N) and the displacement is the vertical height (6 m). So, Work = 350 N times 6 m = 2100 J.
Finally, calculate the power. The formula is Power = Work / Time. The time is 1 minute, which is 60 seconds. So, Power = 2100 J / 60 s = 35 W.
Common mistakes students make in this test
Students often lose marks on this paper by mixing up definitions and forgetting unit conversions. Here are the common errors to avoid.
| Mistake | Correct rule |
|---|---|
| Forgetting to convert cm to m in the numerical | Always convert step height to metres before multiplying by the number of steps. |
| Confusing work and power in the differentiation question | Work is the total energy transferred; power is the rate of doing work. |
| Giving an organic acid as a weak mineral acid example | A weak mineral acid must be a mineral acid, like carbonic acid, not an organic acid like citric acid. |
Frequently asked questions
How many marks is this Science unit test worth?
This unit test is worth 20 marks in total. It is divided equally into Section A (Physics) for 10 marks and Section B (Chemistry) for 10 marks.
Does this paper include Biology questions?
No, this specific UT1 paper from 2025 covers only Physics and Chemistry. It does not include a Biology section.
What does the true or false section test?
The true or false section tests Physics facts. It covers horsepower values, potential energy at a height, energy conversion in a cell, and pendulum energy at the mean position.
