Answer and explanation are free to read — no sign-in required.उत्तर और व्याख्या पढ़ने के लिए साइन-इन आवश्यक नहीं है।

A

Higher pressure → Higher boiling pointअधिक दाब → अधिक क्वथनांक

✓

B

Higher pressure → Lower boiling pointअधिक दाब → कम क्वथनांक

C

Pressure has no effectदाब का कोई प्रभाव नहीं

D

Higher pressure → Freezing onlyअधिक दाब → केवल जमना

Correct Answerसही उत्तर

A. Higher pressure → Higher boiling pointA. अधिक दाब → अधिक क्वथनांक

Explanationव्याख्या

Increasing external pressure generally raises the temperature required for a liquid to boil.

बाहरी दाब बढ़ाने से सामान्यतः द्रव को उबलने के लिए आवश्यक तापमान बढ़ जाता है। ---
