The free quartz suddenly expands at a temperature lower than 600\u00c2\u00b0C<\/strong><\/li>\n<\/ul>\n<p>Quartz is a type of silica mineral that is found in many rocks. When quartz is heated, it expands. This expansion can cause the quartz to break, especially if it is not heated evenly. The expansion of quartz is most rapid at temperatures below 600\u00c2\u00b0C.<\/p>\n<ul>\n<li><strong>B.

Calcium carbonate is a stable compound at room temperature, but it decomposes into calcium oxide (CaO) and carbon dioxide (CO2) when it is heated to high temperatures. This decomposition reaction occurs at temperatures above 800\u00c2\u00b0C.<\/p>\n<ul>\n<li><strong>C. The sand stone with silicates resist a fire in a better way<\/strong><\/li>\n<\/ul>\n<p>Sandstone is a type of sedimentary rock that is made up of sand-sized grains of quartz and other minerals. When sandstone is heated, the sand grains expand and the rock becomes harder. This makes sandstone a good material for building fireplaces and other structures that need to withstand high temperatures.<\/p>\n<ul>\n<li><strong>D. The argillaceous stone though poor in strength can resist fire quite weak<\/strong><\/li>\n<\/ul>\n<p>Argillaceous stone is a type of sedimentary rock that is made up of clay minerals. Clay minerals are hydrous aluminum silicates that have a layered structure. When clay minerals are heated, they lose water and the layers become more tightly packed. This makes argillaceous stone a good material for building firebricks and other structures that need to withstand high temperatures.<\/p>\n<p>In conclusion, all of the statements in the question are correct.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Join Our Telegram Channel Subscribe on YouTube<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[644],"tags":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.2 (Yoast SEO v23.3) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Pick up the correct statement from the following: A.
