Answer the following in one statement:
1. State the temperatures of ice point and steam point on a Celsius scale.
2. Write an expression to show the relationship between Celsius and Fahrenheit scales of
temperature.
3. At what temperature, both the Celsius and Fahrenheit scales are equal?
Answers
1. (i) Ice point is the the mark on Celsius scale at which ice melts. Ice point on the Celsius scale is 0°C. (ii) Steam point on the Celsius scale is the mark at which water changes into steam at normal atmospheric pressure. On Celsius scale it is 100°C.
2 .The conversion formula for a temperature that is expressed on the Celsius (C) scale to its Fahrenheit (F) representation is: F = 9/5C + 32. Celsius temperature scale also called centigrade temperature scale, is the scale based on 0 for the freezing point of water and 100 for the boiling point of water
3.The absolute zero value on the Celsius scale is −273.15∘C. Therefore, the temperature at which both the Celsius and Fahrenheit scales are the same in −40∘.
