A nonexpanding sphere has volume 100 c m 3 and mass 95 g. A liquid density is 1.00 g / c m 3 at 0°C; the sphere becomes neutrally buoyant at 50°C. With V l ( T ) = V l ( 0 ) ( 1 + γ T ) , find γ i

Question

A nonexpanding sphere has volume 100 c m 3 and mass 95 g. A liquid density is 1.00 g / c m 3 at 0°C; the sphere becomes neutrally buoyant at 50°C. With V l ​ ( T ) = V l ​ ( 0 ) ( 1 + γ T ) , find γ in units of 1 0 − 3 K − 1 , to three decimals.

TestHub · Accepted Answer

Neutral density = 95/100 = 0.95 g / cm 3 . Thus 0.95 = ( 1 + 50 y ) 1 ​ , so γ = 50 ( 0.95 1 ​ − 1 ) ​ = 1.0526316 × 1 0 − 3 K − 1 . Requested value = 1.053.
