Rice does <strong>not dissolve<\/strong> in water, nor does it break into fine colloidal particles simply by being added. Instead, the rice <strong>remains visible<\/strong> and, after a short time, <strong>settles to the bottom<\/strong> of the container due to gravity.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This behavior is characteristic of a <strong>suspension<\/strong>:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Heterogeneous mixture<\/strong> (you can see the rice separately).<\/li>\n\n\n\n<li><strong>Particles are large<\/strong> and settle upon standing.<\/li>\n\n\n\n<li>Can be <strong>separated by filtration<\/strong> or decantation.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">In contrast, colloids (like milk or gelatin) have much finer particles that remain <strong>evenly dispersed<\/strong> and <strong>do not settle out<\/strong> easily.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">So, adding a small amount of rice to water\u2014even in tiny amounts\u2014does <strong>not form a colloid<\/strong>.
