How do you measure high temperature? Pyrometer, device for measuring relatively high temperatures, such as are encountered in furnaces. Most pyrometers work by measuring radiation from the body whose temperature is to be measured. How do you measure temperature over 100 degrees? Fahrenheit and Celsius are two different scales for measuring temperature. A thermometer measuring […]
What does high or low specific heat capacity mean?
What does high or low specific heat capacity mean? A substance with a high specific heat capacity can absorb a large quantity of heat before it will raise in temperature (water has a high specific heat). A substance with a low specific heat requires relatively little heat to raise its temperature (copper has a low […]
What best compares radiation and conduction?
What best compares radiation and conduction? The statements that best compares radiation and conduction are the following: both transfer thermal energy from warm objects to cooler objects and both can transfer energy through matter. The difference is that conduction is through direct heat transfer; whereas, radiation transfers heat through waves. What describes how radiation moves? […]
How long does a nuclear fuel rod last?
How long does a nuclear fuel rod last? To make that nuclear reaction that makes that heat, those uranium pellets are the fuel. And just like any fuel, it gets used up eventually. Your 12-foot-long fuel rod full of those uranium pellet, lasts about six years in a reactor, until the fission process uses that […]
Which acid is present in our stomach?
Which acid is present in our stomach? hydrochloric acid Does hydrochloric acid turns red litmus blue? In the given question, first the blue litmus paper was dipped in hydrochloric acid solution. Thus, the litmus would turn red. Further, when dipped in sodium hydroxide solution, it changes back to blue. Thus, the correct answer is B. […]
Can you drive without airbags?
Can you drive without airbags? It’s not illegal to drive without airbags, if your vehicle was manufactured before 1989. So the question then arises: What happens if you have no airbags and get into a crash? Airbags help slow down the change in momentum and help reduce the forces in a crash. How unsafe is […]
What is the SI unit of time?
What is the SI unit of time? second. The second, symbol s, is the SI unit of time. It is defined by taking the fixed numerical value of the cesium frequency ΔνCs, the unperturbed ground-state hyperfine transition frequency of the cesium 133 atom, to be 9 192 631 770 when expressed in the unit Hz, […]
Why protein is not a genetic material?
Why protein is not a genetic material? For a material to be genetic material, it has to replicate, it must be stable both structurally and chemically stable. Furthermore, it must be able to provide a scope for mutations eventually, key for evolution. Where are proteins made? Ribosomes Are proteins made in cytoplasm? Proteins all begin […]
Why is there a difference between the core and the outer core?
What type of parenting is most effective?
What type of parenting is most effective? Authoritative parents have been found to have the most effective parenting style in all sorts of ways: academic, social emotional, and behavioral. Like authoritarian parents, the authoritative parents expect a lot from their children, but also they expect even more from their own behavior. How do I fix […]
