Answer:

Density decreases, Volume increases

Explanation:

As the temperature decreases, the water contracts. Water has maximum density at 4° C. Thereafter, on further decrease in temperature, the water expands on cooling. Actually the water molecules crystallizes into open hexagonal structure.  Thus, volume increases and density decreases. This is the reason that ice floats on water. The mass remains the same.

Answer:

Its density decreases, and its volume increases

Explanation:

Density is defined as Mass/Volume. What happens when water transforms into ice is that its density decreases because the volume the molecules now occupy increases.

The denominator of the rational expression \frac{Mass}{Volume} is now larger (while the numerator stays the same), so the quotient gives a smaller number.

Answer:

Copper

Explanation:

Capacitance is directly proportional to dielectric constant

Aluminium and zinc are highly reactive and have high dielectric contact.

Copper has less dielectric constant hence capacitance will decrease
