The increase in the volume of 10cm³ of mecury when the temperature rises by 100°C is 0.8 cm³. What is the cubic expansivity of mecury?

Y=0.000182 per celsius.

Explanation:

Y=0.000182 per celsius

0.000182 / °C

Explanation:

Thermal volumetric expansion is:

ΔV = γ ΔT V,

where ΔV is the change in volume,

γ is the cubic expansion of coefficient,

ΔT is he change in temperature,

and V is the original volume.

Solving for γ:

γ = ΔV / (ΔT V)

Given ΔV = 0.182 cm³, ΔT = 100°C, and V = 10 cm³:

γ = (0.182 cm³) / (100°C * 10 cm³)

γ = 1.82*10⁻⁴ / °C

γ = 0.000182 / °C
