What is a chemical property simple definition? A chemical property is any of a material’s properties that becomes evident during, or after, a chemical reaction; that is, any quality that can be established only by changing a substance’s chemical identity. They can also be useful to identify an unknown substance or to separate or purify […]
What are the three layers of the earth answer?
What are the three layers of the earth answer? The Earth is divided into three main layers. The dense, hot inner core (yellow), the molten outer core (orange), the mantle (red), and the thin crust (brown), which supports all life in the known universe. Earth’s interior is generally divided into three major layers: the crust, […]
What element is not found in nature?
What element is not found in nature? Technetium. The first element that was synthesised, rather than being discovered in nature, was technetium in 1937. This discovery filled a gap in the periodic table, and the fact that no stable isotopes of technetium exist explains its natural absence on Earth (and the gap). What is a […]
What is a habitat Class 6?
What is a habitat Class 6? The place where organisms live is called habitat. Habitat means a dwelling place (a home). The habitat provides food, water, air, shelter and other needs to organisms. What are the 6 main habitats? We will focus on eight habitats: Polar, Tundra, Evergreen Forests, Seasonal Forests, Grasslands, Deserts, Rainforests, and […]
What is coordinate system and its type?
What is coordinate system and its type? A coordinate system is a method for identifying the location of a point on the earth. Most coordinate systems use two numbers, a coordinate, to identify the location of a point. Each of these numbers indicates the distance between the point and some fixed reference point, called the […]
How do you know what the dependent variable is?
How do you know what the dependent variable is? The variables in a study of a cause-and-effect relationship are called the independent and dependent variables. The independent variable is the cause. Its value is independent of other variables in your study. The dependent variable is the effect. Its value depends on changes in the independent […]
Are there male and female earthworms?
Are there male and female earthworms? Earthworms are hermaphrodites, meaning an individual worm has both male and female reproductive organs. Earthworm mating typically occurs after it has rained and the ground is wet. They emerge from the soil and jut out their anterior end. Do earthworms fertilize their own eggs? Earthworms are hermaphrodites (both female […]
When two electrons have the same spin in the same orbital which principle is being violated?
When two electrons have the same spin in the same orbital which principle is being violated? Pauli’s Exclusion Principle states that no two electrons in the same atom can have identical values for all four of their quantum numbers. In other words, (1) no more than two electrons can occupy the same orbital and (2) […]
What occurs after condensation?
What occurs after condensation? After Water Condenses Some of the water vapor in the atmosphere that condenses is stored in clouds. Clouds are more likely to form when the air is humid and contains more water vapor. The energy released when gaseous water vapor condenses to form liquid water droplets is called latent heat. What […]
Is fog caused by temperature inversion?
Is fog caused by temperature inversion? Sound is affected during fog conditions due to the small distances between water droplets, and air temperature differences. Temperature effect: A fog can be caused by a temperature inversion where cold air is pooled at the surface which helped to create the fog, while warmer air sits above it. […]
