Celsius is used to measure temperature in the metric system.
Celsius is represented by the symbol '°C'.
Another name for Celsius is 'centigrade'.
The freezing point of water is 0°C and the boiling point of water is 100°C under a pressure of one standard atmosphere.
The figure shown is a Celsius/Centigrade thermometer and is marked at 10, so the temperature can be written as 10°C.
A. 15°C
B. 55°C
C. 20°C
D. 25°C
Correct Answer: c
Step 1: In the figure, the marked line indicates the temperature.
Step 2: So, the temperature shown using °C is 15°C.
