Question

Convert to K: 1)-200 °C; (1) 176 ( [Ans.: 0) 293 K (1) 353.15 K]​

Answer 1

Answer:

Converted temperature from Celsius scale to Kelvin scale.

$200^{0}C = 473.15\ K$

$176^{0} C= 449 K$

Explanation:

We know, $0^{0}C$ is equivalent to $273.17 K$

The formula commonly used for changing temperature in Celsius scale to Kelvin scale is given by,

$T_{K}=T_{C}+273.15$        ...(1)

or

$T_{C} = T_{K}- 273.15$        ...(2)

Where $T_k$ is the temperature on the Kelvin scale and $T_c$ is the temperature on the Celsius scale.

1) From the question,

$T_c = 200^{0} C$  

Using equation(1),

$T_{K}=200+273.15$

      $= 473.15\ K$

  2) Given,

$T_{C} = 176^{0} C$

Using equation(1),

$T_{K}=176+273.15$

     $= 449 K$
