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
