Does volume change when liquid is heated? A decrease in temperature caused the water molecules to lose energy and slow down, which results in water molecules that are closer together and a decrease in water volume. When water is heated, it expands, or increases in volume. As water cools, it contracts and decreases in volume. […]
Are transuranium elements synthetic?
Are transuranium elements synthetic? Producing Transuranium Elements Transuranium elements that can be found on Earth now are artificially-generated, synthetic elements made via nuclear reactors or particle accelerators. The half-lives of these elements show a general trend of decreasing as atomic numbers increase. What are synthetic elements used for? Uses of some Synthetic Elements Technetium is […]

How many compounds can carbon form?
How many compounds can carbon form? The four covalent bonding positions of the carbon atom can give rise to a wide diversity of compounds with many functions, accounting for the importance of carbon in living things. Carbon contains four electrons in its outer shell. Therefore, it can form four covalent bonds with other atoms or […]
Why are subtropical highs?
Why are subtropical highs? The warm air at the low latitudes rises and moves toward the poles. The rising air, and the subsequent clouds and precipitation, cause the tropics to be very wet. As the air moves towards the subtropics, it descends over the oceans and creates semi-permanent circulation features called subtropical highs. Where would […]
