Question

A bob weighs 100 g in air, 80 g in liquid at 0°C and 80.2 g at 50°C. Metal α = 1 0 − 5 per °C. Use linear volume laws without dropping ratio terms. Find liquid coefficient in units of 1 0 − 4 per °C to three decimals.

TestHub · Accepted Answer

Buoyancy ratio = 19.8/20 = 0.99 . Metal volume factor = 1.0015 . Thus 0.99 = ( 1 + 50 y ) 1.0015 ​ , giving γ = 2.323232 × 1 0 − 4 per °C. Requested value = 2.323 .
