Muenzaniso wemibvunzo yekuongorora thermometer

3 Mienzaniso yemibvunzo yekuongorora thermometer

1. Pombi yegirazi isina chikero ine doro inofanira kushandiswa tembirichaKureba kwekoramu yedoro kana mugumo wezasi wechubhu yegirazi ukaiswa muchando chakanyunguduka i5 cm uye kukwirira kwekoramu yedoro kana mugumo wezasi wechubhu yegirazi ukaiswa mumvura iri kufashaira i25 cm. Kana ikashandiswa kuyera tembiricha yemvura, kukwirira kwekoramu yedoro i15 cm. Suhu mvura iri….. ^oC
Kukurukurirana
Zvinozivikanwa kuti:
Kureba kwekoramu yedoro panzvimbo yakaderera (ice point) = 5 cm
Kureba kwekoramu yedoro panzvimbo yepamusoro yakatarwa (nzvimbo yekufashaira) = 25 cm
Kureba kwekoramu yedoro pakuyera tembiricha yemvura = 15 cm
Akabvunzwa: Kupisa kwemvura muCelsius scale
Mhinduro:
Nhamba yechikero cheCelsius = 100^o uye musiyano pakukwirira kwekoramu yedoro = 25 cm – 5 cm = 20 cm saka 1^oC yakaenzana nemasentimita mangani? 20 cm / 100^oC = 0,2 cm / ^oC. Saka 1^oC yakaenzana ne 0,2 cm.

Kuchinja kwehurefu hwekoramu yedoro = 15 cm - 5 cm = 10 cm.
10 cm / 0,2 cm = 50
50 X 1^oC = zana^oC

Kupisa kwemvura = 50^oC

2. Chubhu yegirazi isina kukwidziridzwa yakazadzwa nemercury inofanira kushandiswa sethermometer. Kana yakaiswa muchando, mercury column inonyunguduka kusvika pakureba kwe5 cm, uye kana yakaiswa mumvura iri kufashaira, mercury column inenge yakareba 30 cm. Kana thermometer ikaratidza 24^oC ipapo kukwirira kwekoramu yemercury kuri….. cm
Zvinozivikanwa kuti:
Kureba kwekoramu yemercury panzvimbo yakaderera (ice point) = 5 cm
Kureba kwekoramu yemercury panzvimbo yepamusoro yakatarwa (nzvimbo yekufashaira) = 30 cm
Chikero cheThermometer = 24^oC
Akabvunzwa: Kureba kwekoramu yemercury
Mhinduro:
Nhamba yechikero cheCelsius = 100^o uye musiyano pakukwirira kwekoramu yealcohol = 30 cm – 5 cm = 25 cm saka 1 cm yakaenzana nenhamba ^oC? 100 ^oC / 25 cm = 4 ^oC/cm. Saka 1 cm yakaenzana ne 4 ^oC.

24^oC / 4^oC = zana
6 x 1 cm = 6 cm

Kureba kwekoramu yemercury = 5 cm + 6 cm = 11 cm

3. Thermometer P inoratidza kuti mvura inotonhora i10^oP uye pombi yekufashaira yemvura 90^oMubvunzo: Kana tembiricha yechinhu ichi ikayerwa uchishandisa thermometer yeCelsius iri 40^oC, ipapo tembiricha yechinhu ichi kana ikayerwa uchishandisa thermometer P ndiyo….
Kukurukurirana
Zvinozivikanwa kuti:
Mvura inotonhora = 10^oP
Pombi yemvura inofashaira = 90^oP
Kupisa kwechinhu = 40^oC
Akabvunzwa: Kupisa kwechinhu = ….. ^oP?
Mhinduro:
Pachikero cheCelsius, nzvimbo yekuomesa mvura ndeye 0^oC uye pombi yekufashaira yemvura i100^oC. Pane musiyano we100°C pakati penzvimbo yekuomesa nepanzvimbo yekufashaira kwemvura.^o - 0^o = 100^o.
Pachikero cheP, nzvimbo yekuomesa mvura ndeye 10^oP uye pombi yekufashaira yemvura i90^oMubvunzo: Pane musiyano we90 pakati penzvimbo yekuomesa nepanzvimbo yekufashaira kwemvura^o - 10^o = 80^o.
Zvichibva padata iri, fomura yekushandura chikero cheCelsius kuita chikero cheP inowanikwa:

40^oC = …… ^oP?

Tembiricha yechinhu chacho i42^oP.
