Iron expands on heating, and when it gets cooled down, it goes back to its original size.

## When an iron ring is heated the hole becomes group of answer choices?

Homework 7

When an iron ring is heated, the hole becomes Larger
A metal ring with a gap in it is shaped like the letter C. When the hot metal cools, the gap becomes Narrower
Ice has a lower density than water because ice Is composed of open-structured crystals.

## When water at 4 C is heated it expands if it is instead cooled it will?

Water is one of the few exceptions to this behavior. When liquid water is cooled, it contracts like one would expect until a temperature of approximately 4 degrees Celsius is reached. After that, it expands slightly until it reaches the freezing point, and then when it freezes it expands by approximately 9%.

## Which is denser ice at 0 degrees C or water at 4 degrees C?

Water at 4 degree celsius will have higher density. Explanation: Density is related to the ratio of mass and volume.

## What is the reason for ice being less dense than water?

Ice actually has a very different structure than liquid water, in that the molecules align themselves in a regular lattice rather than more randomly as in the liquid form. It happens that the lattice arrangement allows water molecules to be more spread out than in a liquid, and, thus, ice is less dense than water.

## What weighs more 1kg or 1 Litre?

One litre of water has a mass of almost exactly one kilogram when measured at its maximal density, which occurs at about 4 °C. Similarly: one millilitre (1 mL) of water has a mass of about 1 g; 1,000 litres of water has a mass of about 1,000 kg (1 tonne).
