Physical properties of water
Specific heat: how much energy you have to put in to raise the temperature of that mass by one degree Celsius.
-how much energy is needed to raise the temperature of 1g of water by 1 degree Celsius.
Water has unique properties related to its polar nature and tendency to form hydrogen bonds with itself.
-heat of fusion
Heat of vaporization
High specific heat
Water has a high specific heat. It takes a lot of energy to raise its temperature.
High heat of fusion
Large input of energy required to melt water. It takes a lot of energy to raise/lower the temperature of water so the fact that we are made of water makes it hard for us to freeze because living things do not like to be frozen.
High specific heat
-Large input of energy required to raise temperature
High heat of vaporization
Cooling (sweat, evaporation)
When humidity is relatively low, sweat usually evaporates.
Cohesion
Special properties of water
Solid, water and ice
When water freezes, its gets bigger.
-is less dense than liquid water
-floats in liquid water
Water is a versatile solvent due to its polarity especially for anything that is polar and charged.
High dielectric contestant
Water has completely hidden the charge so that that it can’t see the other charge.
Solutes: substance dissolved in a liquid
Solvent: liquid in which they are dissolved
Solution: solutes dissolved in a solvent
Hydrophilic molecules: “water loving”
-readily dissolved in water.

Identification of substance by physical properties Prepared for: Laura, Mudaugh Prepared by: Mohamed, Seaid Rick February 14, 2013 Abstract: The purpose of this lab was to identifying unknown substances by knowing their physical properties as density, melting and boiling point, and their solubility in specific solvent. The unknown solid was determined and found to be a solid Nephthol. Also, the unknown liquid was determined and found to be Cyclohexane. Introduction: Properties are those characteristic…

Essay about Integrated Science Lab: Element Observations

Semimetal Solubility and Mixes 20 drops of distilled water + calcium carbonate crystal is soluble, and a heterogeneous mixture. 20 drops of distilled water + copper sulfate crystal is soluble, and a homogenous mixture. 20 drops of distilled water + methyl alcohol is a homogenous mixture, because they mixed evenly. 20 drops of distilled water + amyl alcohol is a heterogeneous mixture, because they two liquids did not mix together evenly. Physical and Chemical Changes After putting the ammonium…

Separation Anxiety Experiment Summary

comparison to the original heterogeneous mixture. To accomplish this experiment, 25 ml of water was first added to the beaker containing the mixture. The water in combination with the salt and sand mixture was stirred, allowing the salt to dissolve into the water. Then, the sand and salt solution were segregated by the use of a filter, and an evaporation disc and bunsen burner were utilized to evaporate the water, inevitably, leaving behind the salt. This lead to the discovery that the separated sand…

Essay about Nothing: Temperature and Antifreeze

and the reasons they are part of the antifreeze product. There are different kinds of antifreeze mixed with different chemicals, the variances are as follows; Methanol-primary alcohol, inexpensive to produce and distribute, and highly soluble in water “due to its high affinity for Hydrogen bonding”. It’s boiling is lower than most coolant, which is why it is used in antifreeze, but methanol antifreeze are just a short time solution. Ethylene glycol-described when they were first introduced as…

The Importance Of Water

Over two thirds of the earth today are water, and life on earth would be non-existent without the presence of water. The importance of water is so ample that it is the core of human and animal life, and the very essence for a stable environment. Water is an abundant resource on the earth, making up the majority of the world. There are some physical properties that make water one of the most essential elements for life on earth, most of its physical properties cause an interest to biologists because…

Essay on The Unknown Substance Lab

student will use chemical and physical properties to identify unknown substances. 1) Introduction: Physical properties were documented for each substance including visual description, solubility in water and density. A physical property is an observable property of a system and can be either intrinsic or extrinsic if the amount of the substance changes its properties. In addition to physical properties, the substances were evaluated using their chemical properties of reactivity with iodine and acetic…

The Living And Non-Living Components Of The Earth Contain Mixtures

elements or compounds mixed together with no fixed ratio Homogenous: same composition throughout elements and compounds are homogenous mixtures can also be homogenous e.g. wine Heterogeneous: not the same composition throughout e.g. muddy water mixtures can be heterogeneous Matter is anything that has mass and occupies for example gas, liquid or solids Solids: particles are packed closely together and vibrate against each other. The particles are not free to move and have a fixed shape…
