Thermal expansion: 1.000 L of water at 20.00°C will occupy what volume if it is heated to 80.00°C? Water has a volume expansion coefficient of 210 × 10^-6/°C. (Express your answer to 4 significant figures.)

The volume change due to thermal expansion is calculated using the formula ΔV = βV₀ΔT. Here, β = 210 × 10⁻⁶/°C, V₀ = 1.000 L, and ΔT = 80.00°C - 20.00°C = 60.00°C. ΔV = 210 × 10⁻⁶ × 1.000 × 60.00 = 0.0126 L. The new volume is V = V₀ + ΔV = 1.000 + 0.0126 = 1.0126 L, which rounds to 1.013 L to 4 significant figures.
