Vo= 10cm kubik
To= 18'C
alpha(koefisien muai panjang) = 5×10^(-6)/'C
Tt= 20'C
Dit: Vt?
jawab:
gama(koefisien muai volume)= 3×alpha= 3 × 5 × 10^(-6)= 15 × 10^(-6)/'C
deltaV= Vo × gama × deltaT
= 10×15×10^(-6)×(Tt-To)
= 150×10^(-6)×(20-18)
=150×10^(-6)×2
=300×10^(-6) cm kubik
Vt= deltaV-Vo=( 300×10^(-6))-10= -9.9997 cm kubik Semoga membantu
