Solution:

Water is a liquid at 24°C

The thermal volume coefficient (β) of water is 0.000207°C-1 from 20°C to 30 °C and 0.000303°C-1 from 30°C to 40°C.

V = Vo + VoβΔT


At 30°C,

ΔT = (30 - 24)°C = 6°C

V = (3.5 L) + (3.5 L × 0.000207°C-1 × 6°C) = 3.504 L


At 32°C,

ΔT = (32 - 30)°C = 2°C

V = (3.504 L) + (3.504 L × 0.000303°C-1 × 2°C) = 3.506 L = 3.51 L

V = 3.51 L


Answer: 3.51
