Electrical contact materials used in switches brushes and relays must possess which thermal conductivity and melting point?
Electrical contact materials used in switches brushes and relays must possess high thermal conductivity and high melting point.High thermal conductivity dissipates heat effectively and high melting point is to avoid fusing in case of accidental overheating.
What is the motto of High Point University?
High Point University's motto is 'Nil Sine Numine'.
Why si is better than ge?
1.Bandgap is comparatively large hence suitable for low & high temp. 2.High melting point of si makes it stable over wide temp. 3.si is more freely available in nature. 4.leakage current less than ge.
Appearance of strontium at room conditions?
in my high chemical equipment, in my science lab i have found the correct answer and the highly best answer is gas!
What are two possible reasons why mount Kilimanjaro's snow is melting?
two possible reasons are its hot and the mountain might be to high
Why strontium bromide has high melting point?
Strontium bromide has a high melting point due to the strong ionic bonds between the strontium cations and bromide anions in its crystal lattice structure. These bonds require a significant amount of energy to break, resulting in a high melting point.
Why does strontium chloride have a high melting point?
Strontium chloride has a high melting point because of the strong attraction between the strontium cations and chloride anions in its crystal lattice. These ionic bonds require significant energy to break, leading to a high melting point.
Does strontium have a high or low melting point?
Strontium has a relatively low melting point compared to other metals. It melts at 769 degrees Celsius (1416 degrees Fahrenheit).
Why does sodium bromide have a high melting point?
Sodium bromide has a high melting point because of the strong electrostatic forces of attraction between the positively charged sodium ions and negatively charged bromide ions in the crystal lattice. These forces require a significant amount of energy to overcome, resulting in a high melting point for the compound.
What is the Chemical formula for sodium bromide gas?
NaBr is sodium bromide but it is an ionic solid with a high melting point and extremely unlikely to be a gas.
What substance has a high melting point?
One substance that has a high melting point is diamond.
Does carbon have high melting point?
it has a low melting point
Does a metal have a high or low melting point?
All metals have different melting points but they are all high
Does chromium have a high low melting point?
Chromium has a high melting point of 1,857°C (3,375°F) making it a refractory metal.
Do solids have a high or low melting point?
That depends on the solid: ice has a very low melting point, lard and butter have low melting points, chocolate has a relatively low melting point, wax has an intermediate melting point, lead has a high melting point, iron has a very high melting point, tungsten has an extremely high melting point.
Does silicon have a high melting point?
Yes, it has a melting point of 1683 Kelvin.
What elements is hard and dense has a high melting point and boiling point is fairly reactive and has two electrons in its outermost orbit?
This description matches the element calcium (Ca), which is hard and dense, has a high melting and boiling point, is fairly reactive, and has two electrons in its outermost orbit. Calcium typically forms 2+ cations when it reacts with other elements.
