Which statement best describes the role of temperature and pressure in changing the state of matter?
Correct Answerसही उत्तर
A. They affect particle energy, intermolecular distance and attractive forces, enabling state changesA. वे कणों की ऊर्जा, अंतराअणुक दूरी और आकर्षण बल को प्रभावित करके अवस्था परिवर्तन संभव बनाते हैं
Explanationव्याख्या
Changes in temperature and pressure alter particle motion, spacing and intermolecular interactions, allowing matter to change between solid, liquid and gaseous states.
तापमान और दाब में परिवर्तन कणों की गति, उनके बीच की दूरी और अंतराअणुक आकर्षण को प्रभावित करता है, जिससे पदार्थ ठोस, द्रव और गैसीय अवस्थाओं के बीच परिवर्तित हो सकता है।
