A brass ring with an original diameter of 8 cm ... - SS2 Physics Heat and Thermodynamics Question
A brass ring with an original diameter of 8 cm is heated from 20°C to 100°C. If the coefficient of linear expansion for brass is 19 × 10^-6 /°C, what will be its new diameter?
ΔD = α x D x ΔT = (19 × 10^-6 /°C) x (8 cm) x (100°C - 20°C) = 0.136 cm
New diameter = Original diameter + ΔD = 8 cm + 0.136 cm = 8.136 cm
