Q1: According to thermodynamic Farenhite scale, the fundamental interval between ice point to steam point is

ANS:A - 180°

According to the Fahrenheit scale, the fundamental interval between the ice point (32°F) and the steam point (212°F) is 180°F. On the Fahrenheit scale, the ice point is defined as 32°F and the steam point (boiling point of water at standard atmospheric pressure) is defined as 212°F. Therefore, the difference between these two points is 212°F - 32°F = 180°F. This interval is divided into 180 equal parts to form the Fahrenheit temperature scale.
