సరైన సమాధానం మైనస్ 273 డిగ్రీల సెల్సియస్. 

 

  • కేవల మూల బిందువు అనగా సాధ్యమైనంత అతి తక్కువ ఉష్ణోగ్రత మరియు ఈ బిందువు వద్ద ప్రకృతి యొక్క ప్రాథమిక కణాలు అతి తక్కువ ప్రకంపన చలనాన్ని కలిగి ఉంటాయి. దీని ఫలితంగా క్వాంటమ్ మెకానికల్ శూన్య బిందువు యొక్క శక్తి ప్రేరిత కణ కదలికను మాత్రమే కలిగి ఉంటాయి.
  • ఇది 0 కెల్విన్ లేదా మైనస్ 273 డిగ్రీల సెల్సియస్‌కు సమానం.
  • కేవల మూల బిందువు ఉష్ణోగ్రతకు చేరుకోవడం ఆచరణాత్మకంగా అసాధ్యం.
  • ఈ ఉష్ణోగ్రత పదార్ధంలోని కణాలు ఖచ్చితంగా కదలలేని ఉష్ణోగ్రత అంటే వాటిని మరింత నెమ్మదింపజేయడం అసాధ్యం.
  • కెల్విన్ కొలమానంలో కేవల మూల బిందువు కంటే చల్లనిది ఏదీ లేదు.
