Does aluminum melt at a higher temperature than aluminum oxide?
Aluminum oxide has a higher melting point than aluminum. Aluminum oxide melts at around 2072°C, while aluminum melts at a lower temperature of around 660°C.
Which would have higher temperature change water or aluminum?
Starting from the same temperature and for the same amount of heat input, aluminum would wind up with a higher temperature than water because water has a higher heat capacity (it takes more energy to raise its temperature) than aluminum.
What element has a lower first ionization energy then aluminum?
Boron has a lower first ionization energy than aluminum. This is because boron is located in the same group as aluminum but is positioned higher in the periodic table, resulting in a smaller atomic size and a greater effective nuclear charge that holds its electrons more tightly. As a result, aluminum, being in the third period, has a higher first ionization energy than boron, which is in the second period. Other elements with lower ionization energy than aluminum include gallium and indium, which are below aluminum in the same group.
Which has higher first ionization energy aluminum or sodium?
Aluminum has a higher first ionization energy than sodium. This is because aluminum is located further to the right in the periodic table, where elements generally have higher ionization energies due to increased nuclear charge and the effective nuclear attraction on electrons. Sodium, being an alkali metal, has a lower ionization energy as it has a single electron in its outer shell that is more easily removed.
Air moves from where pressure is higher to lower or lower to higher?
Higher to lower.
Does aluminum have lower resistance than copper?
No, aluminum has a higher resistance than copper.
Does aluminum melt at a higher temperature than aluminum oxide?
Aluminum oxide has a higher melting point than aluminum. Aluminum oxide melts at around 2072°C, while aluminum melts at a lower temperature of around 660°C.

Which has higher melt point-galvalume or aluminum?
Galvalume has a higher melt point compared to aluminum. Galvalume is a coated steel product that consists of zinc, aluminum, and silicon, which gives it superior heat resistance. Aluminum has a lower melting point than Galvalume due to its pure metallic form.

Why is is more difficult to weld aluminum than mild steel?
aluminum has a lower melting point, higher thermal conductivity, and doesn't change color before it goes molten
Why is it that with aluminum copper and iron the modulus of elasticity is higher for crystallographic directions with higher linear density?
I meant lower linear density, but I can't change it. So for example for Aluminum the Linear density of [111] is lower than for [110] and that is again lower than [100]. But you notice that the modulus of elasticity is higher for [111] than for [110] and that again is higher than for [100]
What type of wire material should be used for a 100 amp service, aluminum or copper?
Copper wire is recommended for a 100 amp service due to its higher conductivity and lower resistance compared to aluminum wire.
What type of wire material should be used for a 200 amp service, aluminum or copper?
Copper wire is recommended for a 200 amp service due to its higher conductivity and lower resistance compared to aluminum wire.

Higher to lower.
Why does aluminum have a higher melting temperature than sodium?
Aluminum has a higher melting temperature than sodium because aluminum atoms are held together by stronger metallic bonds compared to the weaker metallic bonds between sodium atoms. This results in a higher energy requirement to break these bonds and melt aluminum. Sodium's lower melting temperature is due to its larger atomic size and weaker metallic bonding.
