Question 1/5 Easy Science Exploration: Entering the World of Secondary Science Variables in an experiment Class 9 Level 11

एक छात्र अलग मात्रा में नमक मिलाकर पानी के क्वथन समय को मापता है। नमक की मात्रा कौन सा चर है?

A student adds different amounts of salt and measures the boiling time of water. What type of variable is the amount of salt?

Explanation opens after your attempt
Correct Answer

C. स्वतंत्र चरIndependent variable

Step 1

Concept

The amount of salt is deliberately changed. Therefore it is the independent variable.

Step 2

Why this answer is correct

The correct answer is C. स्वतंत्र चर / Independent variable. The amount of salt is deliberately changed. Therefore it is the independent variable.

Step 3

Exam Tip

नमक की मात्रा जानबूझकर बदली जाती है। इसलिए यह स्वतंत्र चर है।

Question 2/5 Medium Science Exploration: Entering the World of Secondary Science Hypothesis and experimentation Class 9 Level 9

उसी प्रयोग में आश्रित चर कौन सा होगा?

In the same experiment what will be the dependent variable?

Explanation opens after your attempt
Correct Answer

C. क्वथन में लगा समयTime taken to boil

Step 1

Concept

The time taken to boil is the measured outcome. Therefore it is the dependent variable.

Step 2

Why this answer is correct

The correct answer is C. क्वथन में लगा समय / Time taken to boil. The time taken to boil is the measured outcome. Therefore it is the dependent variable.

Step 3

Exam Tip

क्वथन में लगा समय मापा जाने वाला परिणाम है। इसलिए यह आश्रित चर है।

Question 4/5 Easy Science Exploration: Entering the World of Secondary Science Hypothesis and experimentation Class 9 Level 8

एक विद्यार्थी जाँचता है कि नमक की मात्रा जल के उबलने के समय को प्रभावित करती है या नहीं। मापा जाने वाला परिणाम कौन सा है?

A student tests whether the amount of salt affects the time taken for water to boil. Which outcome is measured?

Explanation opens after your attempt
Correct Answer

C. जल के उबलने में लगा समयTime taken for the water to boil

Step 1

Concept

The time taken to boil is the measured outcome so it is the dependent variable. Identify the measured result.

Step 2

Why this answer is correct

The correct answer is C. जल के उबलने में लगा समय / Time taken for the water to boil. The time taken to boil is the measured outcome so it is the dependent variable. Identify the measured result.

Step 3

Exam Tip

उबलने में लगा समय प्रयोग का मापा गया परिणाम है इसलिए यह आश्रित चर है। परीक्षा में मापे गए परिणाम को पहचानें।
