1.Why is electricity obtained on heating a thermocouple?
2. Can copper and iron be combined to make a thermocouple?
3. Is there any other scale of temperature other than the celsius, farengeit and kelvin scale?
4. What is the advantage of absolute scale?
5.In Hope's apparatus why is freezing mixture kept between the upper and lower chambers?
24Q1 not clear
Q2 i think yes
Q3 Reamer scale is another one
Q4 becoz any other value of temp on other scale can be found by adding/subtracting temp of triple point of water
Also fixing value of temp of triple point of water helped in further reseach and saved the scientists from changing the values to celsius scale again and again
