Question

convert the following temperatures to the
Kelvin scale.

(a) 25'C (b) 373'C


​

Answer 1

$\boxed{ \boxed{ \red { \frak{ \: question}}}}$

• Convert the following temperatures to the kelvin scale.

(a) 25° C

(b) 373 ° C

$\boxed{\boxed{ \red{ \frak{answer}}}}$

• To convert the temperature given in °C to kelvin scale we have to add 273 with the temperature temperature given in celsius

• I. e, celsius + 273 = Kelvin

so,

(a) 25°C

• adding 273 to it

• 25°C + 273 = 298 K

(b) 373°C

• adding 273 to it

• 373°C + 273 = 646 K.

Answer 2

Answer:

t∘ C=t+273.15 K.

(a) 25° C=(25+273.15) K=298.15 K

(b) 373°C=(373+273.15) K=646.15 K
