Properties and changes are used to describe matter. A property is a trait of matter‚ when that sample of matter is in a fixed state. There are two different types of properties: physical properties and chemical properties. A change is something that alters the properties of a substance. There are two types of changes: chemical changes and physical changes. A physical property is a property that can be observed without changing the makeup (or composition) of a substance. Some examples of a physical properties

Effects of Changes in Physical Properties on Enzyme Activity By Alex Hoffmann First Individual Lab Report Wednesday 7:30-10:15pm 10/24/12 Meghan Duell Abstract The goal of this lab was to determine the effects of certain physical properties on enzyme activity. Enzyme activity was measured by the height of the bubbles that appeared after the enzyme was added which are proportional to the rate of the reaction when time is constant. The fact that enzyme activity is affected by physical properties

Logical vs. Physical Network Design The typical Top-Down approach to network design uses a systematic method to plan‚ design‚ and implement a new network. Generally‚ the Top-Down methodology involves analysis of the business requirements and goals‚ development of the logical design based on such goals‚ development of the physical design‚ and a phase for testing‚ optimizing‚ and documenting the network design. This paper focuses on the activities performed to create a logical design of a network

Correlation between the chemical activity of Amylase and change in temperature ABSTRACT This experiment focuses on how the change of temperature affects the rate of reaction of amylase. In the experiment there were four different environments that each contained 2 test tubes. Each test tube consisted of the same concentration and amount of starch and amylase. After having each test tube placed in these environments for several minutes a droplets of each mixture was placed onto each slot which

Logical vs. Physical Design of a Network In the world of network design‚ there are two common design types; the logical network design and the physical network design. A logical network design can be described as how the network will be structured‚ basically all logical aspects of the network. According to Webopedia‚ "the logical topology is the way that the signals act on the network media‚ or the way that the data passes through the network from one device to the next without regard to the

Phase Change Lab Report by Dylan Norford Abstract: The purpose of this experiment is to study the energy changes associated with the phase changes of water. In this experiment we know the water is gaining energy so we know the heat is going to be positive and we can use the equation MCΔT to find the energy change. The specific heat will be 1 and we just have to measure the water to find the mass and take the temperature before and after we start to find the energy change. Background: The science

Assignment # Week 04 Word Count: 410 Marketing of physical products VS marketing of services The marketing of physical products and marketing of services expose two different situations in marketing which requires different strategies. With physical product marketing you need to consider the product‚ price‚ place and promotions which are the standard 4Ps approach. When it’s come to marketing of services you need to consider people‚ process and proof on top of the standard 4Ps approach. Services

Physical Abuse vs. Psychological Abuse There is a huge minority of people in the United States that does not realize Psychological/Emotional abuse as an actual form of abuse. The majority of people’s minds go right to physical abuse when indeed there are many other forms of abuse just as if not worse. Physical is easy to spot‚ even if the child does not tell anyone‚ whereas psychological abuse is not seen by anyone else and is very difficult to diagnose. There are many different resources and
