Mehlala e 3 ea lipotso tsa ho lekanya thermometer

1. Phaephe ea khalase e se nang sekala e nang le joala e lokela ho sebelisoa thermometerBophahamo ba kholomo ea joala ha karolo e ka tlase ea phaephe ea khalase e kenngoa ka har'a leqhoa le qhibilihisitsoeng ke 5 cm 'me bophahamo ba kholomo ea joala ha karolo e ka tlase ea phaephe ea khalase e kenngoa ka metsing a belang ke 25 cm. Ha e sebelisoa ho lekanya mocheso oa metsi, bophahamo ba kholomo ea joala ke 15 cm. Suhu metsi ke….. ^oC

Hoa tsebahala hore:
Bophahamo ba kholomo ea joala ntlheng e tlase e tsitsitseng (ntlha ea leqhoa) = 5 cm
Bophahamo ba kholomo ea joala ntlheng e ka holimo e tsitsitseng (ntlha e belang) = 25 cm
Bophahamo ba kholomo ea joala ha ho lekanyetsoa mocheso oa metsi = 15 cm
O botsitse: Mocheso oa metsi ka tekanyo ea Celsius
Karabo:
Palo ea sekala sa Celsius = 100^o 'me phapang bophahamong ba kholomo ea joala = 25 cm - 5 cm = 20 cm kahoo 1^oC e lekana le di-cm tse kae? 20 cm / 100^oC = 0,2 cm / ^oC. Kahoo 1^oC e lekana le 0,2 cm.

Phetoho ea bolelele ba kholomo ea joala = 15 cm - 5 cm = 10 cm.
10 cm / 0,2 cm = 50
50: x 1^oEA-50-C^oC

Mocheso oa metsi = 50 ^o C

2. Phaephe e sa hlophisoang ea khalase e tletseng mercury e lokela ho sebelisoa e le thermometer. Ha e kenngoa ka har'a leqhoa, kholomo ea mercury e qhibiliha ho fihlela bolelele ba 5 cm, 'me ha e kenngoa ka metsing a belang, kholomo ea mercury e bolelele ba 30 cm. Haeba thermometer e bontša 24^oC joale bophahamo ba kholomo ea mercury ke….. cm
Hoa tsebahala hore:
Bophahamo ba kholomo ea mercury ntlheng e tlase e tsitsitseng (ntlha ea leqhoa) = 5 cm
Bophahamo ba kholomo ea mercury ntlheng e ka holimo e tsitsitseng (ntlha e belang) = 30 cm
Sekala sa Thermometer = 24^oC
O botsitse: Bolelele ba kholomo ea mercury
Karabo:
Palo ea sekala sa Celsius = 100^o 'me phapang bophahamong ba kholomo ea joala = 30 cm - 5 cm = 25 cm kahoo 1 cm e lekana le hore na ke tse kae ^oC? 100 ^oC / 25 cm = 4 ^oC/cm. Kahoo 1 cm e lekana le 4 ^oC.

24^oEA-4-C / XNUMX^oEA-6-C
6 x 1 cm = 6 cm

Bolelele ba kholomo ea mercury = 5 cm + 6 cm = 11 cm

3. Thermometer P e bontša hore ntlha ea ho hoama ea metsi ke 10^oP le ntlha e belang ea metsi 90^oP. Haeba mocheso oa ntho ha o lekanngoa ho sebelisoa thermometer ea Celsius e le 40^oC, ebe mocheso oa ntho ha o lekanngoa ho sebelisoa thermometer P ke….
Puisano
Hoa tsebahala hore:
Sebaka sa ho bata sa metsi = 10^oP
Sebaka sa ho belisa metsi = 90^oP
Mocheso oa ntho = 40^oC
O botsitse: Thempereichara ea ntho = ….. ^oP?
Karabo:
Ka tekanyo ea Celsius, ntlha ea ho hoama ea metsi ke 0^oC 'me ntlha ea ho belisa ea metsi ke 100^oC. Ho na le phapang ea 100°C pakeng tsa ntlha ea ho hoama le ntlha ea ho belisa ea metsi.^o - 0^o = 100^o.
Ka tekanyo ea P, ntlha ea ho hoama ea metsi ke 10^oP mme ntlha e belang ya metsi ke 90^oP. Ho na le phapang ea 90 pakeng tsa ntlha ea ho hoama le ntlha ea ho belisa ea metsi^o - 10^o = 80^o.
Ho latela data ena, foromo ea ho fetolela sekala sa Celsius ho ea ho sekala sa P e fumanoa:

40^oC = …… ^oP?

Mocheso oa ntho ke 42^oP.
