Pehea e ana i ka manoanoa o ka Aluminum Foil?

ʻO ka pahu alumini he huahana aluminika me ka mānoanoa o ka pepa alumini mānoanoa i loaʻa ma ka ʻōwili ʻana i kahi pā alumini manoanoa. ʻO ka mānoanoa o ka alumini alumini ka mea maʻamau ma mua o 0.5mm. Pehea e ana i ka mānoanoa o ia ʻano pepa alumini lahilahi?

Nui nā ʻano e ana i ka mānoanoa o ka pepa alumini, ʻO kekahi o nā ʻano hana maʻamau e pili ana i ka helu ʻana o ke kaumaha a me ka nui.

Pono nā mea hana e helu ai i ka mānoanoa o ka foil

• Alumini pepa
• Pihi uila pololei (hiki ke ana i ka pololei o ka grams)
• Pythagoras flask a i ʻole cylinder puka (e ana i kahi o ka foil)
• ʻo Vernier caliper (koho, e ana pono i ka manoanoa)
• Rula (e ana i ka loa a me ka laula o ka foil)

Kaʻina hana 1: E helu i ka mānoanoa ma muli o ke kaumaha, ʻāpana a me ka nui

waiwai waiwai
ʻO ka nui o ka alumini: 2.7 g/cm³

ʻanuʻu

1. Ke kaupaona ana: E hoʻohana i ka unahi uila pololei e kaupaona i ka pahu alumini, e hoʻopaʻa i ke kaumaha ma ka grams (g). Write down the mass of the foil ?

2. E ana i ka ʻāpana o ka foil: E hohola i ka foil, e ana i ka loa a me ka laula o ka foil me ka lula, and calculate the total area of ​​the foil ?:A (i kenimika huinaha cm²).
ʻāpana ʻāpana: A=lōʻihi×ākea

E helu i ka leo: E hoʻohana i ke kumu hoʻopaʻapaʻa no ka alumini e helu i ka leo o ka foil
?:V (i kenimika kubiki cm³).
Ka helu helu: ?=?/?
ʻO ρ ka mānoanoa o ka aluminika, 2.7 g/cm³.

E helu i ka leo: E hoʻohana i ke kumu hoʻopaʻapaʻa no ka alumini e helu i ka leo o ka foil
?:V (i kenimika kubiki cm³).
Ka helu helu: ?=?/?
ʻO ρ ka mānoanoa o ka aluminika, 2.7 g/cm³.

E helu i ka mānoanoa: mānoanoa
? is equal to volume divided by area.
ʻAno mānoanoa:

?=?/?

Kaʻina hana 2:E hoʻohana i ka caliper a i ʻole ka vernier caliper kikohoʻe

E hoʻomākaukau i nā mea hana: hoʻomākaukau i kahi caliper a i ʻole kikohoʻe vernier caliper me ka pololei kiʻekiʻe.
E kau i ka pepa alumini: E kau i ka pepa alumini ma luna o ka ʻili palahalaha a paʻa e hōʻoia i ka palahalaha a me ka wrinkle ʻole.
Hana ana: E hoʻopololei i kekahi ʻaoʻao o ka caliper me ka ʻaoʻao o ka pahu alumini a e kaomi mālie i ka ʻaoʻao ʻē aʻe ma luna o ka pahu alumini no ka hoʻopaʻa pono ʻana o ka caliper me ka pahu alumini a me ke kūpaʻa..
E heluhelu i ka hopena: E heluhelu i ka waiwai ana ma ka caliper, ʻo ia ka mānoanoa o ka pahu alumini.

Kaʻina hana 3:E hoʻohana i kahi anana mānoanoa alumini

E koho i kahi ana mānoanoa: E koho i kahi ana mānoanoa kūpono no ke ana aluminika e hōʻoia i ka pololei a me ke ana ana i nā koi.
Hoʻopili i ka mea kani: E hoʻopololei i ke ana mānoanoa ma mua o ka hoʻohana ʻana e hōʻoia i ka pololei o nā hopena ana.
Hana ana: E kaomi mālie i ka ʻimi o ke ana mānoanoa ma luna o ka pepa alumini e hōʻoia i ka pili piha ʻana o ka ʻimi me ka pepa alumini..
E heluhelu i ka hopena: E hōʻike ʻia ka waiwai mānoanoa o ka pahu alumini ma ka hōʻike o ke ana mānoanoa, a hiki iā ʻoe ke heluhelu pololei.

Kaʻina hana 4:E hoʻohana i ke ʻano ana ʻana o ka mānoanoa fluorescence X-ray

E hoʻomākaukau i nā mea hana: X-ray fluorescence mānoanoa ana a me nā laʻana maʻamau e pili ana.
E kau i ka pepa alumini: E kau i ka pepa aluminika a me ka la'ana ma'amau i ka mea hana X-ray i ka manawa like.
Hana ana: Ma hope o ka hele ʻana o ka X-ray i ka pahu alumini a me ka laʻana maʻamau, ʻoliʻoli ia e ka phosphor ma ka pale phosphor e hana i ka fluorescence.
E helu i ka mānoanoa: E ana i ka ikaika fluorescence o ka phosphor ma ka pale phosphor, a e helu i ka mānoanoa o ka pahu alumini ma muli o ka pilina ma waena o ka ikaika o ka fluorescence a me ka mānoanoa o ka hāpana maʻamau..
