टंगस्टन:
- तापदीप्त बल्बमधील तंतूसाठी टंगस्टन धातूचा वापर केला जातो.
- त्याचा द्रावणांक जास्त असतो आणि गरम केल्यावर त्याची ताकद टिकून राहते.
- लाइट बल्बचे तंतू टंगस्टन मूलद्रव्याने बनलेले असतात.
- टंगस्टनचे वैज्ञानिक नाव ‘वूल्फरम’ आणि त्याचा अणुअंक 74 असल्यामुळे त्याचे चिन्ह ‘W’ आहे.
स्पष्टीकरण:
- टंगस्टनचा द्रावणांक 3300 ते 3500 °C दरम्यान असतो. त्यामुळे पर्याय 4 योग्य आहे.
