temperature before and after mixing was recorded and included in tables. When the experiments were completed analysis was performed using the laws of thermodynamics. The data collected was used in equations to find theoretical values for final equilibrium temperature. The theoretical values were compared with those measured during the experiment. The total average percent difference between the measured final temperature and the theoretical final temperature is less than 5.0%. This low deflection

Biofuels Biofuels are Fuels made from Biomass Biofuels are made from plants‚animals‚ or their waste products. Here I have listed three examples of biofuels beneath. 1 Micro-organisms decompose waste materials to produce biogas. 2 Biogas is usually about 70% methane and somewhere between 20 and 30 % carbon dioxide 3 the way we use it to generate energy is to burn it to heat up water which will then turn a turbine to produce electricity. It is also heard of to heat the water to steam which

Physics lab:9 Equilibrium of parallel force 11/09/2012 By: Camilo Salazar Jillian Ellis Purpose: To understand the conditions need for a rigid body to be in equilibrium when there are forces acting on the body from different sides. Theory: When force is applied on a rigid body for example a ruler it can either be in equilibrium or it can be unbalance. When the force is unbalance what would happen is this motion the body can be either translational or rotational. “A body in translational

Temperature and Equilibrium Virtual Lab Change is influenced by many different factors in many different situations. If you imagine the 400‚000 gallons of water in a stream at the top of a hill‚ you can picture that they will flow down the hill in order to reach equilibrium. But what if the temperature outside is -40 degrees Fahrenheit? How might this change the movement of the water molecules down the hill? This virtual lab will allow you to explore how temperature changes affect two linked

Fuel is one of the important resources in our society. We use the fuels to support our living‚ produce electricity‚ heat homes‚ and operate machinery. Since the fuel is a limited resource‚ the fuel scarcity will be a big issue in the future. The price of the gasoline is currently on the rise. NASCAR cut the volume of fuel cell from twenty gallons to thirteen gallons each car. There is a high demand for a new energy. After the issue of fuel crisis was brought up‚ the society started to be interested

is considered in a state of equilibrium when its properties do not change at time passes. Equilibrium is a state of a reaction where the concentration of all the reactants and all the products remain constant over time. Equilibrium as used in chemical systems means that all the chemical forces in a reaction are in balance and that all physical properties of the system (color‚ density and concentration) of all chemicals species involved remains constant. The equilibrium state can be characterized by

The History of cars By Luke Geisz Today‚ we do not think much of our cars. Everyone has them‚ they’re a common object. They weren’t always like that. Cars used to be only owned by wealthy enthusiasts. They weren’t today’s enclosed‚ climate controlled‚ easy to use devices at all. In fact‚ they were incredibly hard to use. There was no standard controlling system like today’s gas/brake/clutch pedals‚ auto transmission‚ steering wheel‚ and other controlling devices. Some had a steering wheel‚ some

With the fuel crisis seen in the last decade and the current gasoline prices at an all time high there was need for a renewable source of energy that was more affordable and eco-friendly. Solar energy was the perfect answer. Almost all energy on Earth comes from the sun. The Solar technology aims at converting
