If this did not occur ice could sink and destroy living organism. (sea animals) Thermal properties Water resist temperature change‚ due to high specific heat which in turn helps our body (70% water) keeps the water from overheating or freezing.

Should natural law be recognized by the Courts of Canada? Should the Supreme Court of Justice‚ the highest the level of court in Canada‚ allow natural law to be part of the decisions they make in their rulings? In Canada‚ Legal Law is used to settle private and public disputes and also for the sentencing of criminals. Committing a crime is against the law‚ which would mean that the person who committed the offence would need to serve the punishment unless it were special situations‚ such as duress

“Is Density An Intensive Property Of Matter?” By: Mikal Hayden - Gates A. Introduction The first unit we learned in chemistry was Alchemy. In this unit I learned about the extensive and intensive properties of matter. An extensive property is a property of matter that depends on the changes of the substances shape or amount. An intensive property is a property of matter that doesn’t depend on the substances shape or amount. The purpose of this investigation was to prove that density is

Title : Properties of hydrocarbon Objective : 1) To study the properties of hydrocarbons. 2) To determine the unknown samples. Results : Part A : Combustion Compounds Observations Hexane There was orange flame and burned mildly during the burning process. No soots and smoke were produced. C6H14 + 19/2 O2 6CO2 + 7H2O Cyclohexene Orange flame burned vigorously. A small amount of black soot and smoke were produced during the burning process.

Physical properties can be seen‚ touched‚ or even measured without the identity of the substance changing. The identity of the substance can be its shape or color. Three physical forms of a substance are solid‚ liquid‚ and gas. Water for example can transform into all three physical forms without its identity changing. The characteristic of water as a shape can be used as an example of a physical property. Water can be frozen into ice‚ vaporized‚ or liquidized. The shape of water as a solid is
