Question

1. Convert the following temperatures to the celsius scale.
(a) 293 K
(b) 470 K.​

Answer 1

Explanation:

(a) Temp. on Kelvin scale = Temp. on Celsius scale + 273

293 = Temp. on Celsius scale + 273

So, Temp. on Celsius scale = 293 – 273

= 20°C.

(b) Temp. on Kelvin scale = Temp. on Celsius scale + 273

470 = Temp. on Celsius scale + 273

So, Temp. on Celsius scale = 470 – 273

= 197°C.

Answer 2

$\huge\sf\pink{Answer:}$

Kelvin = 273 + C

293 = 273 + C

C = 293 - 273

C = 20 C

Kelvin = 273 + C

470 = 273 + C

C = 470 - 273

C = 197 C
