Given:
Initial temperature, T1 = 20 C
Final temperature, T2 = 40 C
To determine:
The temperature change
Step-by-step explanation:
Convert degree C to Kelvin
Temperature in Kelvin = degree C + 273
T1 = 20 + 273 = 293 K
T2 = 40 + 273 = 313 K
Incremental temperature change = T2 - T1 = 313-293 = 20 K
Ans: The temperature change in kelvin is 20 K
