What is the most heat conductive liquid? Water Why is heat transfer important for thermal fluid design? The key point behind heat transfer fluid technology is the ability to generate high temperatures at low system pressures. Heat transfer fluid technology offers safety, low maintenance, and extending operating lifetimes when compared to traditional technologies such as […]

Which type of reaction releases energy quizlet? Chemical reactions that release energy, usually in the form of heat, are called exothermic reactions. Chemical reactions that absorb energy, usually in the form of heat, are called endothermic reactions. Many types of reactions can be endothermic or exothermic. How is energy released in a chemical reaction quizlet? […]

How is projectile motion used in real life? In real life, the projectile motion finds applications in sports. Playing basketball, football is examples of projectile motion in real life. While throwing a basketball into the basket, the player shoots the ball in such a way that the flight taken by the ball is in the […]

Who helped Tesla? Elon Musk How did the Tesla coil impact society? Circuitry using the Tesla coil was part of the first generation of transmitters to carry wireless telegraphy. Tesla used his brainchild to research such diverse areas as lighting, X-rays and electric power transmission. Customized Tesla coils are now frequently used to ignite powerful […]

What causes seeds to not germinate? The primary reasons for failed germination are: Seeds get eaten – mice, voles, birds, and wireworms all eat seeds. Check to see that the seed is still in the soil. Seeds rot – planted too deeply, over-watered, or in cold weather, our untreated seeds may simply rot. What are […]

Can you boil water with a tealight candle? This calculation suggests that a tea light should be able to boil 4 or 5 pots of water. However, not all the energy will go nto the hot water and you will have to heat up the pot as well as the water. So I would guess […]

Can you touch your eardrum? And if you press on those, it sends shock waves into the inner ear, and the inner ear is responsible for hearing and balance. So if you tap on the eardrum, you’re sending shock waves into the inner ear and you can cause problems with your hearing and balance. Is […]

Is the ruler drop test valid? The ruler-drop test has acceptable test-retest reliability that compares favorably with computerized measures of reaction time. Which finger has the fastest reaction time? The fingers on the outside — i.e. the thumb and little finger — therefore react faster than the middle finger, which is exposed to the “cross […]

What is the difference between emission and absorption spectrum? The main difference between emission and absorption spectra is that an emission spectrum has different coloured lines in the spectrum, whereas an absorption spectrum has dark-coloured lines in the spectrum. What is basic emission? Definition of Emission The basic electronic emission occurs when heat, sunlight, electron […]

Why are my chickens pooping in their nesting boxes? Chickens generally will only poop in the nesting boxes if they are sleeping in them at night. Often young pullets will try to sleep in the boxes instead of on the roosts with the older hens. To prevent this, take any little ones out of the […]
