This liquid freezes.<\/li>\n<li><strong>If it gets cold enough<\/strong>, little bits of ice, or <strong>frost, form.<\/strong><\/li>\n<li>The ice is arranged in the <strong>form of ice crystals.<\/strong><\/li>\n<\/ul>\n<\/li>\n<li>Frost is most <strong>common in low-lying areas.<\/strong>\n<ul>\n<li><strong>Warm air rises<\/strong>, and <strong>cool air sinks<\/strong>\u2014cool air is denser than warm air.<\/li>\n<li>That means there are usually more water molecules in cool air than in warm air.<\/li>\n<li><strong>As cool air collects in valleys, frost forms.<\/strong><\/li>\n<\/ul>\n<\/li>\n<li>Frost <strong>usually forms at night<\/strong>, when the <strong>air temperature is cooler.\u00a0<\/strong>\n<ul>\n<li><strong>Once the sun rises and warms the air<\/strong> around the frosted object, <strong>frost melts <\/strong>quickly.<\/li>\n<\/ul>\n<\/li>\n<li>There are <strong>different types of frost<\/strong>. The most common are radiation frost (also called hoarfrost), advection frost, window frost, and rime.\n<ul>\n<li><strong>Radiation frost<\/strong> is frost in the <strong>form of tiny ice crystals<\/strong> that usually shows up on the <strong>ground or exposed objects outside<\/strong>. Hoarfrost also forms in <strong>refrigerators and freezers<\/strong>.<\/li>\n<li><strong>Advection frost<\/strong> is a collection of <strong>small ice spikes<\/strong>. Advection frost forms when a <strong>cold wind blows over <\/strong>the <strong>branches of trees, poles<\/strong>, and other surfaces.<\/li>\n<li><strong>Window frost<\/strong> forms when a <strong>glass window is exposed to cold air outside<\/strong> and <strong>moist air inside<\/strong>. Window frost is familiar to winter residents of cold climates. Indoor heat and cold outdoor temperatures form this type of frost.<\/li>\n<li><strong>Rime<\/strong> is frost that <strong>forms quickly, usually in very cold, wet climates<\/strong>. Rime also forms in windy weather. Rime sometimes <strong>looks like solid ice<\/strong>. <strong>Ships traveling through cold places<\/strong> like the Arctic Ocean often <strong>end up with rime covering<\/strong> at least part of the exposed part of the ship.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<hr \/>\n<h3><strong>Q1<\/strong>: What is graphene oxide?<\/h3>\n<p>Graphene oxide (GO) is the oxidized form of graphene. It is a single-atomic-layered material that is formed by the oxidation of graphite which is cheap and readily available. Graphene oxide is easy to process since it is dispersible in water and other solvents. Due to the oxygen in its lattice, graphene oxide is not conductive, but it can be reduced to graphene by chemical methods.<\/p>\n<p><strong>Source:<\/strong> <a href=\"https:\/\/epaper.thehindu.com\/ccidist-ws\/th\/th_delhi\/issues\/105843\/OPS\/GOTDHK8RP.1+G1QDHLCPR.1.html\" target=\"_blank\" rel=\"nofollow noopener\">Layer of graphene oxide halts frost formation on flat areas<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Frost is water vapor, or water in gas form, that becomes solid.<\/p>\n","protected":false},"author":5,"featured_media":27737,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1],"tags":[],"class_list":{"0":"post-27736","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-upsc-prelims-current-affairs","8":"no-featured-image-padding"},"acf":[],"_links":{"self":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/27736","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/comments?post=27736"}],"version-history":[{"count":0,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/27736\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media\/27737"}],"wp:attachment":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media?parent=27736"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/categories?post=27736"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/tags?post=27736"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
