What is difference between igneous and sedimentary rocks? There are three kinds of rock: igneous, sedimentary, and metamorphic. Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water. They accumulate in layers. What are the […]
Which gas is highly compressible?
Which gas is highly compressible? Gases are compressible because most of the volume of a gas is composed of the large amounts of empty space between the gas particles. At room temperature and standard pressure, the average distance between gas molecules is about ten times the diameter of the molecules themselves. How much work is […]
When electrons are being shared between atoms it is called a n?
When electrons are being shared between atoms it is called a n? A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, […]

What is negative beta decay explain with an example?
What is negative beta decay explain with an example? In beta decay. In electron emission, also called negative beta decay (symbolized β−-decay), an unstable nucleus emits an energetic electron (of relatively small mass) and an antineutrino (with little or possibly no rest mass), and a neutron in the nucleus becomes a proton that remains in […]
Do we eat sunlight?
Do we eat sunlight? Yes, definitely. Almost all living things on earth are fueled by the sun either directly or indirectly. (The exception is organisms that live near volcanic vents deep in the ocean.) Energy from the sun is taken in by plants and eaten by animals. Do humans get energy directly from the sun? […]
