Question

Water expands about 8.7% when it freezes. Assume the volume of 1 g of water is 1 cm^3. Calculate ΔV for the freezing of 1 g of ice.

A) 0.087 cm^3
B) 0.01 cm^3
C) 1.087 cm^3
D) 0.87 cm^3

Answer 1

The change in volume when 1 g of ice freezes is 0.087 cm³.

Step-by-step explanation:

To calculate ΔV for the freezing of 1 g of ice, we need to find the change in volume when water freezes. Water expands about 8.7% when it freezes, meaning its volume increases by 8.7%.

Since the volume of 1 g of water is given as 1 cm³, we can calculate ΔV by finding 8.7% of 1 cm³.

8.7% of 1 cm³ = 0.087 cm³

Therefore, the correct answer is (A) 0.087 cm³.
