Question

Demonstrează ca:
Delta T(grade Kelvin)= Delta t(grade Celsius)

Answer 1

ΔT=T-T0, Δt=t-t0

Stim ca: 0°C=273,15 K; 1°C=274,15K; 2°C=275,15K; 
Adica: x°C=(x+273,15)K

Atunci se respecta relatia: T=t+273,15 si T0=t0+273,15

Inlocuim in formula:

ΔT=t+273,15-(t0+273,15)
ΔT=t+273,15-t0-273,15
ΔT=t-t0, unde t-t0=Δt
ΔT=Δt

c.t.d.
