Mienzaniso yemibvunzo nemafomura ekuyerwa kwetembiricha uye kuyera thermometer

Chiyero chekupisa

1. Tembiricha yemvura inodziya zvichienderana nechikero cheCelsius thermometer i45. Zvichienderana nechikero cheFahrenheit, tembiricha iyi….

A. 25
B. 57
C. 81
D. 113

Kukurukurirana
Zvinozivikanwa kuti:
T_C = 45^oC
Akabvunzwa: T_F = ….. ^oF ?

Mhinduro chaiyo ndiD.

2. Thermometer isingawanzo shandiswa inoshandisa chikero chekuyera chine poindi yechando yemvura ye -15 ^o S uye poindi yemvura inofashaira ye +60 ^o S. Kana thermometer ichiratidza kukosha kwe 10 o S, kukosha kwetembiricha muFahrenheit scale….

A. 28^o
B. 35^o
C. 57^o
D. 92^o

Kukurukurirana
Zvinozivikanwa kuti:
Mvura inotonhora = -15^oS
Mvura iri kufashaira = +60^oS
Vakabvunza: 10^oS = …..^oF
Mhinduro:
Pachikero cheFahrenheit, nzvimbo yekuomesa mvura i32^oF uye pombi yekufashaira yemvura i212^oF. Pane musiyano we212 pakati penzvimbo yekuomesa nepanzvimbo yekufashaira kwemvura^o - 32^o = 180^o.
Pachiyero cheCelsius, mvura inotonhora i0^oC uye pombi yekufashaira yemvura i100^oC. Pane musiyano we100°C pakati penzvimbo yekuomesa nepanzvimbo yekufashaira kwemvura.^o - 0^o = 100^o.
Pachikero cheS, nzvimbo yekuomesa mvura ndeye -15^oS uye pombi yekufashaira yemvura i60^oS. Pane musiyano we60 pakati penzvimbo yekuomesa nepanzvimbo yekufashaira kwemvura^o – (-15^o= = 60^o + 15^o = 75^o.

Chinja chikero cheS kuita chikero cheCelsius:

Kuongororwa kweThermometer

3. Chubhu yegirazi yakazadzwa nedoro ichashandiswa sethermometer. Kureba kwekoramu yedoro kana mugumo wekoramu wasangana nechando chakanyunguduka nemvura iri kufashaira i4 cm uye 28 cm, zvichiteerana. Tembiricha yemvura inoita kuti koramu yedoro isvike 16 cm….. ^oC
A. 67,7
B. 50
C. 16
D. 12
Kukurukurirana
Zvinozivikanwa kuti:
Kureba kwekoramu yedoro kana mugumo wepombi wasangana nechando chakanyunguduka = ​​4 cm
Kureba kwekoramu yedoro kana mugumo wepombi wasangana nemvura iri kufashaira = 28 cm
Mubvunzo: Kupisa kwemvura kunoita kuti koramu yedoro ikwire 16 cm... ^oC
Mhinduro:
Tembiricha iyo chando chinonyunguduka (chando chiri kunyunguduka) i0^oC kuitira kuti kukwirira kwekoramu yedoro kuve 4 cm, zvakaenzana ne4^oC. Tembiricha yemvura iri kufashaira i100^oC kuitira kuti kukwirira kwekoramu yedoro kuve 28 cm, zvakaenzana ne100^oC.

Musiyano pakukwirira kwekoramu yedoro i28 cm - 4 cm = 24 cm.
Musiyano uripo pakati pechikero chekupisa cheCelsius i100^oC - 0^oC = zana^oC.

100^oC / 24 cm = 4,17 ^oC / cm
Saka koramu yealcohol yakareba 1 cm yakaenzana ne4,17 ^oC.

Kana kukwirira kwekoramu yedoro kuri 4 cm, tembiricha yemvura iri 0^oC. Kana kureba kwekoramu yealcohol kuri 16 cm, tembiricha yemvura iri muCelsius yakaita sei? 16 cm - 4 cm = 12 cm. Saka 12 x 4,17 = 50,04 ^oC.
Mhinduro chaiyo ndeiyi B.

4. Chisingadiwi kuti pave nechiyero chethermometer ndeichi….
A. nzvimbo yepamusoro yakatarwa
B. pombi yekufashaira
C. nzvimbo yakaderera yakatarwa
D. upamhi hwechikero
Kukurukurirana
Chinodiwa kuti uzive chiyero chethermometer ipombi yepamusoro (boiling point) uye pombi yepasi (freezing point). Saka chisingadiwi kuti uzive chiyero chethermometer zvichibva pamubvunzo uri pamusoro apa ihupamhi hwechiyero.

5. Thermometer isina kurongwa ine mercury. Kana ikaiswa muchando, mercury column inenge yakareba 5 cm uye kana ikaiswa mumvura iri kufashaira, mercury column inenge yakareba 30 cm. Kana thermometer ikaratidzwa 25^oC kureba kwekoramu yemercury ndiko….
A. 6,25 cm
B. 10,25 cm
C. 11,25 cm
Kureba 22,50 cm
Kukurukurirana
Zvinozivikanwa kuti:
Kureba kwechikamu chemercury kana chakaiswa muchando chakanyunguduka = ​​5 cm
Kureba kwechikamu chemercury kana chakaiswa mumvura iri kufashaira = 30 cm
Mubvunzo: Kureba kwechikamu chemercury kana thermometer ichiratidza 25^oC
Mhinduro:
Tembiricha yekunyunguduka kwechando (chando chiri kunyunguduka) i0^oC saka kureba kwekoramu yemercury i5 cm iyo yakaenzana ne0^oC. Tembiricha yemvura iri kufashaira i100^oC saka kureba kwekoramu yemercury i30 cm iyo yakaenzana ne100^oC.

Musiyano pakureba kwekoramu yemercury i30 cm - 5 cm = 25 cm.
Musiyano uripo pakati pechikero chekupisa cheCelsius i100^oC - 0^oC = zana^oC.

25 masendimita / 100^oC = 0,25 cm / ^oC
Kana simbi yemercury ikawedzera ne 0,25 cm, zvakafanana nekuwedzera tembiricha yemvura ne 1 oC.

Kana tembiricha yemvura iri 0^oC, kureba kwekoramu yemercury i5 cm. Saka kana tembiricha yemvura iri 25^oC ipapo kureba kwekoramu yemercury i5 cm + (0,25 x 25) = 5 cm + 6,25 cm = 11,25 cm.
