The most accurate answer to what goes up and never comes down is a person's age. Another common answer is a person's height. Heat and smoke are also accurate answers for what goes up and never comes down, due to the fact that heat rises.Know More
What goes up and never comes down is a popular riddle, as gravity causes practically everything in the universe to rise and fall. One of the most common wrong answers to this riddle is the sun, as it is a common belief that the sun comes up every day. The sun actually does not move, it is the Earth that rotates around the sun, giving the appearance of a rising sun. Helium balloons are also often perceived as going up and never coming down, but the helium reaches a certain point in the atmosphere and begins to dissipate, in turn, causing the balloon to descend back to the ground slowly.
Another common wrong answer to this riddle is gas. While gases definitely rise, they reach a limit in space and do not continue upward. The same goes for moisture. Humorous answers to this popular riddle include a cow walking up the stairs, inflation and gas prices.Learn more about States of Matter
The physical properties of matter are texture, appearance, odor, color, boiling point, melting point, solubility, density, polarity and others. Physical properties describe the observations of the three states of matter. The three states of matter are gases, liquids and solids.Full Answer >
When a gas is heated, its molecules start moving at a much faster speed and this consequently causes an increase in pressure within the container holding the gas. If the container is not strong enough, the activity of the gas molecules is likely to cause it to burst.Full Answer >
Mercury, the only metal that remains liquid at room temperature, is more than 13 times denser than water. One way of comparing densities of liquids is by combining them to determine which floats on top of the other. However, some liquids dissolve in water, making this method unreliable. Creosote and sulfuric acid are both denser than water, but sulfuric acid is an aqueous solution that mixes with water.Full Answer >
Solids are denser than liquids, and liquids are denser than gases at room temperature. Solids are atoms and molecules in a relatively motionless crystal lattice configuration. Liquids are comprised of molecules with more energy and aren't confined to a lattice. Gases are high energy, and their molecules are spaced apart.Full Answer >
