Thermometer and temperature measurement

1. An objeck has temperature of 75 ⁰C . exspress the temperature of the object in the reamure, Fahrenheit, and Kelvin

2. An objeck has temperature of 100 ⁰F. exspress the temperature of the object in the celcius, reamure, and kelvin

3. A thermometer with ⁰X scale has the freezing point of water at 20⁰X and boiling point of water at 140 ⁰X. if the temperature of an object is 6⁰X, determine the temperature of the object is fahrenheat and Kelvin scales!

4. A thermometer with ⁰X scale has the freezing point of water at -40⁰X and boiling point of water at 160 ⁰X. if the temperature of an object is 25⁰X, determine the temperature of the object is fahrenheat and Kelvin scales!

5. Thermometer A pada es yang sedang melebur menunjukkan -30⁰C dan pada air yang mendidih 150⁰C. apabila satu benda suhunya 50⁰C, berapa skala yang ditunjukkan oleh thermometer A.

6. Pada skala berapa thermometer celcius dan fahrenheat menunjukkan skala yang sama?

7. Pada skala berapa thermometer reamur dan fahrenheat menunjukkan skala yang sama?

Body exspansion

1. Sepotong logam mepunyai panjang 100 cm dan suhu awal 30⁰C dipanaskan sampai 130⁰C. berapakah pertambahan panjang logam itu jika koefisien muai panjangnya 1,2.10^-5/⁰C?

2. A steel has length of 100cm at temperature 30⁰C. if the length of the steel now is 100.1 cm and α = 10^-5/⁰C, determine the temperature of steel now!

3. Satu gelas pyrex yang mempunyai volume 300 cm³ pada suhu 20⁰C berisi penuh dengan air. Berapa cm³ air akan tumpah apabila seluruhnya dipanasi sampai 70⁰C?

(diketahui α pirex=3.10^-6/⁰C dan γ air =21.10^-5/⁰C)

4. Bejana dapat menampung air maksimum 50 ml pada suhu 20⁰C. ketika bejana dan air tersebut dipanaskan sampai 60⁰C, maka sebanyak 0,5 g air hilang (massa jenis air padda suhu 60⁰C adalah 0,98 g/ml.

a. Berapakah koefisien muai volume bejana?

b. Apa jenis bahan bejana yang paling mungkin?

5. A piece of metal has initial length of 10 meters at temperature 20⁰C, then is warmed up and reaches temperature of 120⁰C. if the coefficient of length expantion is 10^-4/K, then its length increment is…..

6. If the temperature is increased from 0⁰C to 100⁰C, the length of a piece of steel is increasing from 1000m to 1001m, what is the change of length if it is warmed up from 0⁰C to 120⁰C?
