Why boiling point varies with pressure? The normal boiling point is the temperature at which the vapor pressure of the liquid is equal to standard pressure. Because atmospheric pressure can change based on location, the boiling point of a liquid changes with the external pressure. Why is it easier to boil water at higher altitudes? […]
What is the best wood flooring to use over radiant heat?
What is the best wood flooring to use over radiant heat? One of the best options over radiant heat is to use an engineered hardwood floor. The inherent dimensional stability of engineered hardwood floors makes it a great choice for radiant heat systems. Certain solid hardwood floors are appropriate as well. Can you put rugs […]
What is genetic variation in biology quizlet?
What is genetic variation in biology quizlet? Genetic variation is the diversity present in the DNA of a population. Explain how genetic variation occurs within and between populations of a species. Genetic variation within a population occurs via mutation and sexual reproduction, and can be measured using average heterozygosity. Where does genetic variation come from […]
How can yield strength be reduced?
How can yield strength be reduced? For the majority of materials, the yield strength decreases with increasing temperature. In metals, this decrease in yield strength is due to the thermal activation of dislocation motion, resulting in easier plastic deformation at higher temperatures. What happens when plastic is cooled? Once a plastic has been cooled below […]
What type of bonds is formed when sodium combines with oxygen?
What type of bonds is formed when sodium combines with oxygen? Sodium will react with oxygen and form an ionic compound. What happens when sodium bonds with oxygen? When sodium (Na) atoms bond with one oxygen (O) atom, there have to be two sodium atoms, each with an extra electron. Each of these sodium atoms […]
Which of the following is not an example of the second law of thermodynamics?
Which of the following is not an example of the second law of thermodynamics? Which one of the following is not an example of the second law of thermodynamics? CO2 is exhaled as a by-product of aerobic respiration is not an example of second law of thermodynamics. Is the second law of thermodynamics a consequence […]
What is the average IQ of a Navy SEAL?
What does adding baking soda to your laundry do?
What does adding baking soda to your laundry do? It may sound like an old wives’ tale, but adding baking soda to your regular amount of liquid laundry detergent truly will make your colored clothing brighter and your whites whiter. Baking soda is a natural deodorizer and cleanser, and it also softens the water, which […]
What describes something in nature without explaining it?
What describes something in nature without explaining it? Unlike a theory, a scientific law describes an observed pattern in nature without attempting to explain it. A hypothesis is a possible explanation for a set of observations or answer to a scientific question. How do you know if a claim is scientific? To evaluate the scientific […]
Why does it rain so much near the equator?
Why does it rain so much near the equator? Near the Earth’s equator, solar heating is intense year round. The Sun heats the ocean, evaporating tremendous amounts of water. As air rises, it cools, and water vapor condenses into rain. This daily cycle of heating, evaporation, and convection creates a persistent band of showers and […]
