One cubic foot of water can store 312 Btu of thermal energy. On a cold winter day a well-constructed home may require 100,000 Btu of nighttime space heating. What is the volume of water required to store this energy?

Respuesta :

Answer:

Explanation:

Heat capacity = mass x specific heat

heat capacity ∝ mass

∝ volume

heat capacity ∝ volume

H₁ / H₂ = V₁ / V₂

H₁ and H₂ are heat capacity corresponding to volume V₁ and V₂.

312 / 100000  = 1 / V₂

V₂ = 100000 / 312

= 320.51 cubic foot.
