Is Earth a closed system? The Earth is a closed system for matter That is a list of all basic elemental materials on our planet. Because of gravity, matter (comprising all solids, liquids and gases) does not leave the system. It is a closed box. So the chemical matter we have on Earth will always […]

How many types of bonds can a carbon atom form?
How many types of bonds can a carbon atom form? four Can a single carbon atom exist on its own? Pure carbon can exist in different forms, depending on how its atoms are arranged. The forms include diamond, graphite, and fullerenes. All three forms exist as crystals, but they have different structures. Their different structures, […]
What are the three primary Colours as proposed by the trichromatic theory?
What are the three primary Colours as proposed by the trichromatic theory? The Young–Helmholtz theory of color vision is the best known trichromatic theory. Subsequent studies determined that there are three different retinal cone photopigments with peak sensitivities roughly corresponding to the three primary colors of trichromatic theory: blue, green, and red. How well does […]
What is scale variable?
What is scale variable? Essentially, a scale variable is a measurement variable — a variable that has a numeric value. This could be an issue if you’ve assigned numbers to represent categories, so you should define each variable within the measurement area individually. What types of scales are used to measure the variables? Four Types […]
What happens if base-emitter junction is reverse biased?
What happens if base-emitter junction is reverse biased? If you reverse bias the diode, the diode cuts off. Now, the base-emitter junction in a transistor is going to essentially turn the transistor on or off. Now, the base-collector junction will not have that same power, but the base-emitter junction will determine whether the transistor is […]
Is sand a good thermal insulator?
Is sand a good thermal insulator? Saturated sand has a thermal conductivity in the range of 2-4 W/m-K which causes the sand layer thickness to go astronomical. Thus it can be shown that sand is a good replacement for fiberglass pipe insulation in underground, direct buried applications. It’s easier to install and costs less. Does […]
Which organ is responsible for oxidizing 90% of consumed alcohol?
Which organ is responsible for oxidizing 90% of consumed alcohol? Alcoholic liver disease—As the chief organ responsible for the breakdown of alcohol, the liver is particularly vulnerable to alcohol metabolism’s effects. More than 90 percent of people who drink heavily develop fatty liver, a type of liver disease. Which alcohol is easiest on your liver? […]
Why do plasma balls make you smell?
Why do plasma balls make you smell? If a hand is placed close to the globe it produces a faint smell of ozone, as the gas is produced by high voltage interaction with atmospheric oxygen. Some globes have a control knob that varies the amount of power going to the center electrode. What happens if […]
What should I expect at a developmental assessment?
What should I expect at a developmental assessment? Your assessment will be tailored to your child’s age and suspected problem or delay. In general, you can expect that you’ll spend time answering a host of detailed questions about your child’s growth, physical movements, behavior, play, and interactions with family members and the rest of the […]
