Question

one cubic foot of water can store 312btu. a home requires 100,000 what is the volume​

Answer 1

Volume of water required to store 100,000 Btu of thermal energy is $320.51foot^{3}$ .

Explanation:

The complete question is : 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? In this question , it's given that One cubic foot of water can store 312 Btu of thermal energy or 312 Btu takes 1 cubic foot of water ,So

1 Btu takes  $\frac{1}{312}$ cubic foot of water

Therefore, 100,000 Btu takes:

⇒ $volume = \frac{1}{312}(100,000)$ $foot^{3}$

⇒ $volume = \frac{100,000}{312}$ $foot^{3}$

⇒ $volume = 320.51$ $foot^{3}$

∴ Volume of water required to store 100,000 Btu of thermal energy is $320.51foot^{3}$ .
