What is the application of third law of thermodynamics? The third law of thermodynamics states that the entropy of a perfect crystal at a temperature of zero Kelvin (absolute zero) is equal to zero. Entropy, denoted by ‘S’, is a measure of the disorder/randomness in a closed system. All the atoms and molecules in the […]
How do you calculate waves?
How do you calculate waves? Wave speed is the distance a wave travels in a given amount of time, such as the number of meters it travels per second. Wave speed is related to wavelength and wave frequency by the equation: Speed = Wavelength x Frequency. This equation can be used to calculate wave speed […]
What is the main advantage of Fibre optic cables over copper cables?
What is the main advantage of Fibre optic cables over copper cables? Fiber optic cables have a core that carries light to transmit data. This allows fiber optic cables to carry signals at speeds that are only about 31 percent slower than the speed of light—faster than Cat5 or Cat6 copper cables. There is also […]
Why is gravity proportional to mass?
Why is gravity proportional to mass? According to theory, the reason mass is proportional to gravity is because everything with mass emits tiny particles called gravitons. These gravitons are responsible for gravitational attraction. The more mass, the more gravitons. Most gravitons exist in a cloud around the object. What is the similarities between mass and […]
What is the best anti-vibration material?
What is the best anti-vibration material? Rubber Where are vibration isolators used? Vibration Isolation Pad Mounts Pads or sheets constructed of flexible materials such as elastomers, rubber, cork, dense foam and laminate materials are often used under heavy machinery, under common household items, in vehicles and other applications to reduce noise and vibration transmission. What […]
How is pressure maintained in a reactor?
How is pressure maintained in a reactor? As shown above, mass flow meters are often used to control the input of various gases (and sometimes liquids) into the heated reactor containing the catalyst sample. A back pressure regulator is typically used on the exit of the reactor to maintain stable pressure control for the catalysis […]
Do Low flow shower heads save money?
Do Low flow shower heads save money? Low flow showerheads reduce both water and energy usage, since reducing the amount of water used by the shower will also reduce the amount of energy used to heat it. In doing so, low flow showerheads also reduce the amount of money spent on utilities. Are Low flow […]
Which is costly brass or bronze?
Which is costly brass or bronze? While all three contain copper, the percentage is far lower in Brass and Bronze than in pure copper as alloying elements are mixed in. This reduces the cost of brass and bronze. Bronze is usually more expensive than brass, partly due to the processes required to manufacture bronze. How […]
What is wet lab skills?
What is wet lab skills? A wet lab is one where drugs, chemicals, and other types of biological matter can be analyzed and tested by using various liquids. On the other hand, a dry lab environment focuses more on applied or computational mathematical analyses via the creation of computer-generated models or simulations. What are some […]
