Question

At the Ice Bowl in Buffalo workers laid down 1 cm layers of water at a time to prevent bubbles from forming in the ice. A NHL regulation rink is 210 by 85 ft (1658 m2). a. If the water was at 0 C when it was frozen how much energy (in Joules) did the cooling plants need to freeze each layer?

Answer 1

Answer:

energy required = 553772 kJ

Explanation:

we know that

1 m = 100 cm

1 m³ = 1000 L

so volume will be

water volume = 1,658 × $\frac{1}{100}$ m³

water volume = 1.658 m³

so water volume we can say = 1,658 liters of water

and

we know that 1 mg of water  require =  334 J energy

so here  here we can say 1 L =   334 kJ energy

as that 1658 L energy require = 1658 × 334 kJ

energy required = 553772 kJ
