Physical properties include characteristics like density, color, mass, volume, temperature, and phase (solid, liquid, gas). These properties can be observed directly or measured without altering the substance&#8217;s identity.<\/p>\n\n\n\n<p>In contrast, a <strong>chemical property<\/strong> describes a substance&#8217;s ability to undergo a chemical change, which results in the formation of a new substance. Chemical properties are associated with how a substance interacts with other substances and involves chemical reactions that change the substance&#8217;s chemical composition.<\/p>\n\n\n\n<p>Now, let\u2019s examine each option:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>A) It reacts with base to form water.<\/strong><br>This is a <strong>chemical property<\/strong>, not a physical property. The reaction with a base (which forms water) is a chemical reaction that results in the formation of new substances (water and possibly a salt), which indicates a change in the substance\u2019s chemical composition. Therefore, this characteristic is a chemical property.<\/li>\n\n\n\n<li><strong>B) Its density is 1.84 g\/mL.<\/strong><br>Density is a <strong>physical property<\/strong> because it can be observed and measured without changing the substance\u2019s chemical composition. The density of a substance is the ratio of its mass to its volume and can be determined by physical methods.<\/li>\n\n\n\n<li><strong>C) It tastes sour.<\/strong><br>The taste of a substance is generally considered a <strong>physical property<\/strong> as it is a sensory observation. While it can be influenced by the chemical composition (e.g., sourness is typically associated with acidic compounds), the act of tasting itself is an observation of a physical property.<\/li>\n\n\n\n<li><strong>D) It is a white-colored solid.<\/strong><br>The color of a substance is also a <strong>physical property<\/strong> because it is an observable characteristic that doesn\u2019t require a chemical change. The color can be noted visually and does not involve a chemical reaction.<\/li>\n<\/ol>\n\n\n\n<p>Thus, the correct answer is <strong>A<\/strong>, as it describes a chemical property, while the others describe physical properties.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A solid substance is subjected to a number of tests and observations.
