What is contraction and expansion in case of water
Answers
Answer:
In terms of thermal expansion water shows a typical behaviour. It contracts on heating between 0 degree C and 4 degree C. The volume of given amount of water decreases as it is cooled from room temperature, until its temperature reaches 4 degree C. Below 4 degree C, the volume increases and density decreases.
Answer:
A contraction is a shortened version of the written and spoken forms of a word, syllable, or word group, created by omission of internal letters and sounds.
With the addition of water, the baking powder makes tiny bubbles of air. As the cake bakes, the heat from the oven makes the air bubbles expand and causes the cake to rise. The heat from the oven will eventually set the eggs in the mixture and cake will stay “risen” even when removed from the oven.
