Question

1) Converta as temperaturas em graus Celsius indicadas a seguir para as escalas Kelvin e Fahrenheit. Graus Celsius Kelvin Fahrenheit a) 20°C b) 50°C c) -10°C d) -40°C e) 200ºC

Answer 1

A) 20C---> K=C+273 ---> K= 20+273---> K=293

C/5=TF-32/9 → 20/5=TF-32/9→4=TF-32/9  →36+32=TF→ TF=68

B)50C → K=50+273 → K=323

50/5=TF-32/9 →10=TF-32/9  → 90+32=TF→TF= 122

C)-10C → K=-10+273 → K=263

-10/5=TF-32/9 → -5.9 + 32= TF → TF= -18+32 → TF= 14

D)-40C → K=-40+273 → K=233

-40/5=TF-32/9 → -8.9+32= TF → TF= -72+32 → TF= -40

E)200C → K=200+273 → K=473

200/5=TF-32/9 → 40.9-32=TF → TF= 360+32 → TF= 392

Espero ter ajudado :)
Qualquer coisa só chamar!
