Why would air pressure be greater at sea level than it would be on the top of a mountain? The lower the altitude, the greater the air pressure. At the top of a mountain the molecules are less dense and there is less air pressure. While at sea level the molecules are more dense and […]

Does gold have the same properties as silver?
Does gold have the same properties as silver? A review of the table shows that gold and silver are very similar to each other. Generally, compared to platinum and palladium, gold and silver have a lower melting and boiling point, are better conductors, softer, more reflective, and more abundant. Why do copper and silver have […]
Which fluid has the highest viscosity?
Which fluid has the highest viscosity? For instance, honey has a much higher viscosity than water. Viscosity is measured using a viscometer. Measured values span several orders of magnitude. Of all fluids, gases have the lowest viscosities, and thick liquids have the highest. Does volume affect viscosity? Most recent answer. The more viscous a fluid […]
