# What is the value of absolute zero on the Celsius scale? Verified
279.6k+ views
Hint: The value on the Celsius scale can be converted to the Kelvin scale by adding $273$ to it. The absolute temperature scale is the Kelvin, which has the symbol with a capital K. We write temperatures in Kelvin without the degree symbol, absolute zero is $0$K.

Formula used: ${{\text{T}}_{{\text{Kelvin}}}}{\text{ = }}{{\text{T}}_{{\text{Celsius}}}} + 273.15$
Here, ${{\text{T}}_{{\text{Celsius}}}}$ is said to be as Temperature in Celsius, and ${{\text{T}}_{{\text{Kelvin}}}}$ is said to be as Temperature in Kelvin.

Complete step-by-step solution:
Absolute zero can be defined as the temperature at which the pressure becomes zero, Temperature at which a thermodynamic system has all-time low energy , it corresponds to $- 273.15{\text{ }}^\circ C$. It appeared that an ideal gas at constant pressure would reach zero volume and now it is said to be as absolute zero. At absolute temperature , the pressure of anything becomes close to zero but doesn’t become zero . The temperature of $- 273.15{\text{ }}^\circ C$ is called absolute zero.
${{\text{T}}_{{\text{Kelvin}}}}{\text{ = }}{{\text{T}}_{{\text{Celsius}}}} + 273.15$------(1)
At absolute zero, ${{\text{T}}_{{\text{Kelvin}}}} = 0$
Now by using the formula, let us substitute ${{\text{T}}_{{\text{Kelvin}}}} = 0$ in equation (1)
So we get ${\text{0 = }}{{\text{T}}_{{\text{Celsius}}}} + 273.15$
Now, move $273.15$ to the other side, so we get ${{\text{T}}_{{\text{Celsius}}}} = - 273.15$
and this is the value of absolute temperature on the Celsius scale is equal to $- 273.15{\text{ }}^\circ C$.
Each degree is equal to one degree on the Celsius scale is called Kelvin or the absolute scale of temperature.

Note: Value of absolute temperature on the Celsius scale is equal to $- 273.15{\text{ }}^\circ C$.
Absolute zero, is a Temperature at which a thermodynamic system has the lowest energy. It corresponds to $- 273.15{\text{ }}^\circ C$ on the Celsius temperature scale.
