Turning the gaseous state back into the solid state is known as <em>Deposition</em><em>.</em> Eg. Napthalene balls, camphor, etc.</p><p></p><p>d. <strong>Boiling</strong><strong> </strong><strong>Point</strong><strong>:</strong><strong> </strong>It is the fixed temperature at which a liquid starts to <a href="https://interviewquestions.tuteehub.com/tag/boil-400181" style="font-weight:bold;" target="_blank" title="Click to know more about BOIL">BOIL</a>.

Evaporation takes place at all temperatures. Alcohol evaporates at 78⁰C.</p><p>The factors affecting the rate of evaporation are:</p><p>1. Humidity around the liquid.</p><p>2. The air blown on the surface of the liquid.</p><p>3. Volatile the liquid.</p><p>4. Larger the surface area.</p><p></p><p><strong>Q4</strong><strong>.</strong><strong> </strong>Evaporation is an endothermic reaction, henceforth it requires heat. It takes away the heat from its surroundings and produce a sensation of cooling. Eg. We feel cool, when air blows over our <a href="https://interviewquestions.tuteehub.com/tag/body-900196" style="font-weight:bold;" target="_blank" title="Click to know more about BODY">BODY</a> sweat.</p><p></p><p><strong>I</strong><strong> </strong><strong><a href="https://interviewquestions.tuteehub.com/tag/knew-2148414" style="font-weight:bold;" target="_blank" title="Click to know more about KNEW">KNEW</a></strong><strong> </strong><strong>just</strong><strong> </strong><strong>these</strong><strong> </strong><strong>many</strong><strong> </strong><strong>questions</strong><strong> </strong><strong>only</strong><strong>.</strong><strong> </strong><strong>Hope</strong><strong> </strong><strong>they</strong><strong> </strong><strong>helped</strong><strong> </strong><strong>you</strong><strong>.</strong></p><p></p><p><strong>Thank</strong><strong> </strong><strong>you</strong><strong>.</strong></p><p></p><p></p><p></p><p></p><p></p><p></p><p></p></body></html> | |
