सांद्रीभवना दरम्यान उत्सर्जित होणाऱ्या उष्णतेस ______ म्हणतात. The heat released at the time of condensation is called as
The heat energy released when water vapor condenses into liquid water or ice is known as latent heat of condensation.
खालीलपैकी योग्य विधान/ने ओळखू : विधान 'अ' : विशिष्ट तापमानावर ठराविक आकारमानाच्या हवेत असलेले वाष्पाचे प्रमाण म्हणजे त्या हवेची सापेक्ष आर्द्रता होय. विधान 'ब' : हवेची निरपेक्ष आर्द्रता आणि त्याच तापमानावर त्या हवेची कमाल वाष्प धारण शक्ती यांच्या गुणोत्तराला विशिष्ट आर्द्रता म्हणतात. Identify the correct statement/s from the following : Statement 'A' : The weight of water vapour per unit volume of air in specific temperature is called relative humidity. Statement 'B' : Specific humidity is the ratio of air water vapour content to its water vapour capacity at a given temperature.
(a)विशिष्ट तापमानावर ठराविक आकारमानाच्या हवेत असलेले वाष्पाचे प्रमाण म्हणजे त्या हवेची सापेक्ष आर्द्रता होय.
(b)हवेची निरपेक्ष आर्द्रता आणि त्याच तापमानावर त्या हवेची कमाल वाष्प धारण शक्ती यांच्या गुणोत्तराला विशिष्ट आर्द्रता म्हणतात.
Both statements are incorrect. Relative humidity is the ratio of water vapour present to the capacity at a given temperature, not just the absolute weight per unit volume. Specific humidity is the mass of water vapour per unit mass of moist air, not the ratio stated.
वाफेचे रूपांतर बर्फात होण्याच्या क्रियेस ________ म्हणतात. The process of conversion of water vapour into ice is known as
Sublimation is the direct transition of a substance from solid to gas or vice versa (such as water vapour directly into ice or frost, or solid to vapour).
