This gives water fluidity, making it a liquid at room temperature.<\/li>\n\n\n\n<li><strong>Boiling and freezing points<\/strong>: Water\u2019s boiling point is 100\u00b0C, and its freezing point is 0\u00b0C, both of which fall within the typical room temperature range (around 20-25\u00b0C), keeping it in a liquid state.<\/li>\n<\/ol>\n\n\n\n<p><strong>(b)<\/strong> <strong>An iron almirah is a solid at room temperature<\/strong>:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>High melting point<\/strong>: Iron has a high melting point of 1,538\u00b0C, which is far above room temperature. As a result, iron remains solid at typical room temperature.<\/li>\n\n\n\n<li><strong>Strong atomic bonding<\/strong>: The strong metallic bonds between iron atoms hold them in a rigid structure, which prevents the material from becoming a liquid at room temperature.<\/li>\n<\/ol>\n\n\n\n<p class=\"has-medium-font-size\"><strong>What is Boiling Point?<\/strong><\/p>\n\n\n\n<p>The boiling point is the temperature at which a liquid turns into a gas (vaporises) throughout the entire liquid. This occurs when the liquid\u2019s vapour pressure equals the external pressure acting on it.<\/p>\n\n\n\n<p><strong>Process of Boiling Point:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>As heat is applied to a liquid, its molecules move faster, increasing the vapour pressure.<\/li>\n\n\n\n<li>When this vapour pressure equals the surrounding atmospheric pressure, the liquid begins to boil.<\/li>\n<\/ul>\n\n\n\n<p><strong>Factors Influencing Boiling Point:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>External Pressure:<\/strong> At higher altitudes, the atmospheric pressure is lower, so liquids boil at lower temperatures. At sea level (1 atm), water boils at 100\u00b0C, but at higher elevations, it boils at lower temperatures.<\/li>\n\n\n\n<li><strong>Intermolecular Forces: <\/strong>Liquids with stronger intermolecular forces (e.g., hydrogen bonds in water) have higher boiling points because more energy is needed to break these forces.<\/li>\n<\/ul>\n\n\n\n<p><strong>Examples:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Boiling point of Water: 100\u00b0C at 1 atm pressure.<\/li>\n\n\n\n<li>Boiling point of Mercury: 356.7\u00b0C at 1 atm pressure.<\/li>\n<\/ul>\n\n\n\n<p class=\"has-medium-font-size\"><strong>What is Melting Point?<\/strong><\/p>\n\n\n\n<p>The melting point is the temperature at which a solid turns into a liquid. It is the temperature where the solid and liquid phases of a substance are in equilibrium under a given pressure.<\/p>\n\n\n\n<p><strong>Process of Melting Point:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>As heat is applied to a solid, its molecules gain <strong>kinetic energy<\/strong>, causing them to vibrate more intensely.<\/li>\n\n\n\n<li>At the melting point, these vibrations become strong enough to overcome the intermolecular forces that hold the molecules in place, causing the solid to melt into a liquid.<\/li>\n<\/ul>\n\n\n\n<p><strong>Factors Influencing Melting Point:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Pressure:<\/strong> For most substances, increasing pressure raises the melting point, but there are exceptions (e.g., ice melts at a lower temperature under high pressure).<\/li>\n\n\n\n<li><strong>Intermolecular Forces: <\/strong>Substances with stronger intermolecular forces (e.g., ionic bonds in salts or metallic bonds in iron) have higher melting points because more energy is required to break the bonds.<\/li>\n<\/ul>\n\n\n\n<p><strong>Examples:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Melting point of Water: 0\u00b0C (solid to liquid transition).<\/li>\n\n\n\n<li>Melting point of Iron: 1,538\u00b0C (solid to liquid transition).<\/li>\n<\/ul>\n\n\n\n<p class=\"has-text-align-center has-medium-font-size\"><strong>Common Chemistry Questions:<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table class=\"has-very-light-gray-to-cyan-bluish-gray-gradient-background has-background has-fixed-layout\"><tbody><tr><td><a href=\"https:\/\/leverageedu.com\/questions-answers\/what-do-you-mean-by-polar-protic-and-polar-aprotic-solvents\/\"><strong>What Do You Mean by Polar Protic and Polar Aprotic Solvents?<\/strong><\/a><\/td><td><a href=\"https:\/\/leverageedu.com\/questions-answers\/what-is-the-molecular-weight-of-naoh\/\"><strong>What is the Molecular Weight of NaOH?<\/strong><\/a><\/td><\/tr><tr><td><a href=\"https:\/\/leverageedu.com\/questions-answers\/difference-between-solid-liquid-and-gas-phase\/\"><strong>What is the Difference Between Solid, Liquid and Gas Phase?<\/strong><\/a><\/td><td><a href=\"https:\/\/leverageedu.com\/questions-answers\/how-do-you-determine-the-mass-of-potassium-in-33-5-g-of-kcl\/\"><strong>How do you determine the mass of potassium in 33.5 g of KCl?<\/strong><\/a><\/td><\/tr><\/tbody><\/table><\/figure>\n","protected":false},"excerpt":{"rendered":"The explanation to the question is: (a) Water is a liquid at room temperature due to its molecular&hellip;\n","protected":false},"author":82,"featured_media":901,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"editor_notices":[],"footnotes":""},"categories":[10,4],"tags":[],"class_list":{"0":"post-891","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-chemistry","8":"category-science"},"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.5 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Give two reasons to justify (a) Water at room temperature is a liquid (b) An iron almirah is a solid at room temperature<\/title>\n<meta name=\"description\" content=\"Give two reasons to justify (a) Water at room temperature is a liquid (b) An iron almirah is a solid at room temperature: (a) Water has a melting point below room temperature and hydrogen bonds keep it liquid.
