Una varilla de cobre de 95 cm de longitud, tiene una temperatura de 20°C. ¿Cuál será su longitudinal, si se calienta a 100°C?¿Cuánto aumentó su longitud?

Answers

Answer 1

Answer:

95,1368 cm

Explanation:

Dado que;

Expansividad lineal del cobre α = 1.8 × 10- ^ 5 ° C - ^ 1

longitud original de cobre L1 = 95 cm

Longitud final del cobre L2 =?

temperatura inicial Θ1 = 20 ° C

Temperatura final Θ2 = 100 ° C

α = L2 - L1 / L1 (Θ2 - Θ1)

L2 - L1 = αL1 (Θ2 - Θ1)

L2 = αL1 (Θ2 - Θ1) - L1

L2 = 1.8 × 10- ^ 5 × 95 (100 - 20) + 95

L2 = 95,1368 cm
