Answer:
Part a:
a) t (°C) = 100°C
b) t (°C) = 20°C
c) t (°C) = 197°C
Part b:
a) T = 273 K
b) T = 523 K
c) T = 3003 K
Step-by-step explanation:
Data Given
Temperature given in Kelvin.
1) 373k
2) 293K
3) 470K
Hint:
t = T - 273
Temperature given Celsius
a) 0C
b) 250C
c) 2730C
Hint : T = 273 + t
Solution:
In the first prat of the question we have to convert temperature from kelvin to Celsius scale.
As the hint given in this question is given as
t = T - 273
This is derived from the Formula
T = t (°C) + 273 . . . . . . . . .. . . . (1)
where
T = is the Kelvin temperature
t = is the Celsius temperature
So, to convert the K to °C, we rearrange the equation (1)
t (°C) = T - 273 . . . . . . . . . . . . . . (2)
Now put the value in equation 2
a) 373 K
t (°C) = T - 273
t (°C) = 373 - 273
t (°C) = 100°C
__________________________
b) 293 K
t (°C) = T - 273
t (°C) = 293 - 273
t (°C) = 20°C
__________________________
c) 470 K
t (°C) = T - 273
t (°C) = 470 - 273
t (°C) = 197°C
---------------------------------------------------------------------------------
In the 2nd prat of the question we have to convert temperature from Celsius scale to kelvin.
As the hint given in this question is given as
T = 273 + t
This is the Formula
T = t (°C) + 273 . . . . . . . . .. . . . (1)
where
T = is the Kelvin temperature
t = is the Celsius temperature
Now put the value in equation 1
a) 0°C
T = t (°C) + 273
T = 0 + 273
T = 273 K
_____________________________
b) 250°C
T = t (°C) + 273
T = 250 + 273
T = 523 K
_____________________________
c) 2730°C
T = t (°C) + 273
T = 2730 + 273
T = 3003 K
