Question

16.Convert a)296 K intothe Celsius Scale b) Convert 370 C into Kelvin Scale.​

Answer 1

Answer:

a) 23° C

b) 643 K

Explanation:

Formula used:

1. Temperature in Celcius = Temperature in Kelvin - 273
2. Temperature in Kelvin = Temperature in Celcius + 273

(The second formula can be obtained by transposing first formula)

Part A:

• Temperature in Kelvin = 296 K
• Temperature in Celcius = ?

Applying the first formula,

Temperature in Celcius = 296 - 273

⇒ Temperature in Celcius = 23°C

∴ 296 K = 23° C

____________________________

Part B:

• Temperature in Celcius = 370° C
• Temperature in Kelvin = ?

Applying the second formula;

Temperature in Kelvin = Temperature in celcius + 273

⇒ Temperature in Kelvin = 370 + 273

⇒ Temperature in Kelvin = 643 K

∴ 370° C = 643 K

Answer 2

To find :

i) 296 k into Celsius

ii) 370 C into Kelvin

Formula to be used :

• Kelvin = 273+ Celsius
• Celsius = Kelvin-273

Solution:

i) 296 K in Celsius :

296-273 = 23 C

ii) 370 C in Kelvin:

370+ 273 = 643 K
