Question

Exer
1. Convert the following temperatures to the celsius scale.
(a) 293 K
(b) 470 K
2. Convert the following temperatures to the kelvin scale.
(a) 25°C
(b) 373°C​

Answer 1

Explanation:

1. Temperature in Kelvin = Temperature in °C + 273

Substitute the given value in the equation and then calculate the other unknown value.

a) 293 K = (293 – 273)

= 20 °C

b) 470 K = (470 – 273)

= 197 °C

2.Remember the relationship:Temperature in Kelvin = Temperature in oC + 273 Substitute the given value in the equation and then calculate the other unknown value.

a) 25° C = (25 + 273) K

= 298 K

b) 373° C = (373 + 273) K

= 646 K
