Answer 1

Answer:

180°c it answer in this question

Answer 2

Explanation:

Celsius, or centigrade, is a scale and unit of measurement for temperature. It is one of the most commonly used temperature units.

Key Points

The degree Celsius (°C) can refer to a specific temperature on the Celsius scale as well as a unit to indicate a temperature interval, a difference between two temperatures or an uncertainty.

The Celsius scale is currently defined by two different temperatures: absolute zero and the triple point of Vienna Standard Mean Ocean Water (VSMOW; specially purified water).

Based on this, the relationship between Celsius and Kelvin is as follows:

T

T

Key Terms

kelvin: in the International System of Units, the base unit of thermodynamic temperature; 1/273.16 of the thermodynamic temperature of the triple point of water; symbolized as K

absolute zero: The coldest possible temperature: zero on the Kelvin scale and approximately -273.15°C and -459.67°F. The total absence of heat; the temperature at which motion of all molecules would cease.

standard atmosphere: an international reference pressure defined as 101.325 kPa and formerly used as a unit of pressure

Celsius, also known as centigrade, is a scale to measure temperature. The unit of measurement is the degree Celsius (°C). It is one of the most commonly used temperature units in the world. The unit system is named after the Swedish astronomer Anders Celsius (1701-1744), who developed a similar temperature scale.
