Question

Numerical problems.

a) convert 300kelvin into the Celsius scale.
b) Convert 220° C into kelvin scale.
c) Convert 30° C into fahrenheit scale.
d) Convert 260° F into °C​

Answer 1

a) 27 degree Celsius

b) 493.15K

c) 86 Fahrenheit

d) 126.667 degrees celsius

Step-by-step explanation:

a) To convert from Kelvin scale to Celsius scale, subtract 273 from Kelvin scale

Hence, 300 - 273 = 27 degree celsius

b) The temperature T in Kelvin (K) is equal to the temperature T in degrees Celsius (°C) plus 273.15, that conversion formula:

T(K) = T(°C) + 273.15

hence, 220 + 273.15 = 493.15K

c) The formula to convert Celsius to Fahrenheit is °F = °C × (9/5) + 32

F = [ C × (9/5) + 32 ]

Given that, C = 30

F = 30 × (9/5) + 32

F = 54 + 32

F = 86

Thus, 30 °C is equivalent to 86 °F.

d) Formula

(260°F − 32) × 5/9 = 126.667°C
