The temperature of an object is raised by 120°C. The resulting increase in its absolute temperature is
50K
120 K
200K
393K
Penjelasan
Object temperature = 120ºC
So, 0ºC + 273 = K
K = 120 + 273 = 393K
Increase in temperature = 0ºC to 120ºC
⇒ 273K to 393K = ( 393 - 273) = 120K
NOTE: The change in temperature in Kelvin is equal to the change in temperature in Celsius: ΔT(K) = ΔT(°C)
