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 cell has highest efficiency?
Which cell has highest efficiency? Scientists have developed a solar cell that is capable of converting direct sunlight into electricity with 44.5 percent efficiency — making it, potentially, the most efficient solar cell in the world. Current solar technology only converts electricity with a maximum efficiency of about 25 percent. Which metal is used to […]
How can you tell if a precipitate has formed in solution?
How can you tell if a precipitate has formed in solution? The identity of the precipitate can often be determined by examining solubility rules. It also occurs in single displacement when one metal ion in solution is replaced by another metal ion. Notice the new solid forming on the bottom of the tube. Which solution […]

Nuclear Power. Hydroelectric Energy. Wave Energy. Biofuels. Natural Gas. Geothermal Power. Wind Energy. What is the three basic energy system? During exercise, your […]
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, […]

Perpendicular Parking: This type of parking is common in parking lots, where people park their cars for a longer duration. Parallel Parking: Illegal Parking: Lot Parking: Bay Parking: Between two Vehicles: What […]
What do u mean by uniform circular motion?
What do u mean by uniform circular motion? Uniform circular motion can be described as the motion of an object in a circle at a constant speed. As an object moves in a circle, it is constantly changing its direction. At all instances, the object is moving tangent to the circle. Nonetheless, it is accelerating […]
