Does boiling point increase across a period? Melting and boiling points increase across the three metals because of the increasing strength of their metallic bonds. The number of electrons which each atom can contribute to the delocalized “sea of electrons” increases. The atoms also get smaller and have more protons as you go from sodium […]
What happens to the coefficient of friction when the weight is increased?
What happens to the coefficient of friction when the weight is increased? What happens to the coefficient of friction, when weight of the body is doubled? Coefficient of Friction is defined as the ratio of the max resisting force parallel to the contact surface to the forces pressing them together. Therefore, by doubling the weight, […]
Why does more bandwidth mean more data?
Why does more bandwidth mean more data? To transfer data, a signal must change in some way and the rate at which these changes occur influences the rate at which information can be transferred. Thus, more bandwidth corresponds to a higher maximum rate of data transfer. How do I know my Internet bandwidth? How To […]
Why does the inner core of Earth remain solid even though it is very hot?
What are 2 ways viruses can reproduce?
What are 2 ways viruses can reproduce? There are two processes used by viruses to replicate: the lytic cycle and lysogenic cycle. Some viruses reproduce using both methods, while others only use the lytic cycle. In the lytic cycle, the virus attaches to the host cell and injects its DNA. How virus is created? Viruses […]
What are the 6 types of fossils?
What are the 6 types of fossils? There are 6 types of fossils. They are body, trace, cast and mold, living, s carbon film, and petrified wood. What are the two main types of fossils? There are two types of fossils- the body fossils and the trace fossils. Body fossils include preserved remains of an […]
Does specific heat depend on phase?
Does specific heat depend on phase? The symbol c stands for specific heat and depends on the material and phase. The specific heat is the amount of heat necessary to change the temperature of 1.00 kg of mass by 1.00ºC. What material has the highest specific heat? Liquid water What does CPK 1.33 mean? capable […]
What is K in capacitor?
What is K in capacitor? Also, sometimes capacitors are marked with the capital letter K to signify a value of one thousand pico-Farads, so for example, a capacitor with the markings of 100K would be 100 x 1000pF or 100nF. Are capacitors color coded? The capacitors use a capacitor color code similar to the resistors […]
Would a propeller work in space?
Would a propeller work in space? Turbine engines and propellers use air from the atmosphere as the working fluid, but rockets use the combustion exhaust gases. In outer space there is no atmosphere so turbines and propellers can not work there. This explains why a rocket works in space but a turbine engine or a […]
