Is asphalt the same as blacktop? The materials that are used to make blacktop and asphalt are the same. Both are made from two ingredients: bitumen and crushed stone. The difference lies in how those ingredients are combined to make the final product. How much hotter is asphalt? Asphalt can be 40-60 degrees hotter than […]

What is the connection between temperature and kinetic energy? What is the relationship between kinetic energy and speed? temperature is the average kinetic energy of the particles of matter. the hotter something is the more kinetic energy it has. What is the connection between temperature and kinetic energy quizlet? What is the connection between temperature […]

Why are there no more than 5 links in a food chain? Most food chains have no more than four or five links. There cannot be too many links in a single food chain because the animals at the end of the chain would not get enough food (and hence, energy) to stay alive. These […]

What type of reaction is the reaction of magnesium with oxygen? Oxygen and magnesium combine in a chemical reaction to form this compound. After it burns, it forms a white powder of the magnesium oxide. Magnesium gives up two electrons to oxygen atoms to form this powdery product. This is an exothermic reaction. What happens […]

How fast does water carry heat away from the body? He went down so fast and never came up again.” Here’s how it can happen and what you can do about it. Cold water carries heat away from the body 25 times faster than air of the same temperature and as a result, the body […]

What is a specific and nonspecific immune response? Nonspecific protective mechanisms repel all microorganisms equally, while the specific immune responses are tailored to particular types of invaders. These immune mechanisms also help eliminate abnormal cells of the body that can develop into cancer. What are the two different specific immune responses? There are two types […]

Why are most plants green in color? The longer answer lies in the details of photosynthesis, the electromagnetic spectrum, energy and “special pairs” of chlorophyll molecules in each plant cell. As such, plants look green because they absorb red light most efficiently and the green light is reflected. Who named Chlorophyll is a green Coloured […]

What is the name for the MnO4 ion? Permanganate | MnO4- – PubChem. What is the name of potassium ion? It is an alkali metal cation, an elemental potassium, a monovalent inorganic cation and a monoatomic monocation. Potassium is the major cation (positive ion) inside animal cells, while sodium is the major cation outside animal […]

What is the special of Science Day? National Science Day is celebrated in India on 28 February each year to mark the discovery of the Raman effect by Indian physicist Sir C. V. Raman on 28 February 1928. For his discovery, Sir C.V. Raman was awarded the Nobel Prize in Physics in 1930. What is […]

What are the six components of skill related fitness? There are six skill-related fitness components: agility, balance, coordination, speed, power, and reaction time. Skilled athletes typically excel in all six areas. What are the benefits of skill related fitness? Strength and flexibility are important in reducing risks of osteoporosis and improving functional capacity. Skill-related fitness […]
