THERMAL SENSITIVITY REPORT METHOD Measuring oxygen concentration: One glass vial was filled with 7-13 Artermia. After incubation‚ uncapped at 15oC for 5 minutes‚ the glass vial was sealed underwater and incubated again for another 5 minutes. After this 5-minute incubation‚ a reading of oxygen concentration was taken via a fibre-optic cable held onto a sensor spot on the vial. The vial was then returned to the incubation bath. The first reading represented time zero and subsequent readings

THERMAL POLLUTION It is one of the pollution that effects on living things and the environment badly. The definition of thermal pollution is the degradation of water quality by any process that changes ambient water temperature. A common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers. When water used as a coolant is returned to the natural environment at a higher temperature‚ the change in temperature decreases oxygen supply‚ and affects ecosystem composition

After a nine-week period of $100‚000 investment divided equally among four stocks (3D Systems‚ Microsoft‚ Nordstrom and Sony)‚ our portfolio has been liquidated‚ analyzed‚ and compared to the surrounding markets by investing the same $100‚000 in each of 3 different indexes: the VFINX‚ the VHGEX and the NASDAQ 100. These portfolios represent the overall U.S.‚ global equity and technology market‚ respectively. Shown below are the results from the portfolio and its comparisons. Performance/Risk Assessment

I was given the possibility to choose between explaining how thermal physics is used in the design of railways or roads and bridges. I chose to explain how it is used in railways because I find it particular more interesting. After that‚ I will explain what Thermal Expansion is

Thermal Expansion Thermal expansion is the tendency of matter to change in volume in response to a change in temperature‚ through heat transfer. The coefficient of thermal expansion describes how the size of an object changes with a change in temperature. Specifically‚ it measures the fractional change in size per degree change in temperature at a constant pressure. Several types of coefficients have been developed: volumetric‚ area‚ and linear. This is used depending on the particular application

Lab #7: Thermal Energy Heat is thermal energy being transferred from one place to another‚ because of temperature changes. This can take place by three processes. These three processes are known as conduction‚ convection‚ and radiation. When we place two objects with different temperatures in contact with each other‚ the heat from the hotter object will immediately and automatically flow to the colder object. This is known as conduction. Some objects make excellent conductors of heat while

THERMAL EQUILIBRIUM AND TEMPERATURE Two systems are said to be in thermal equilibrium with each other‚ if they are at the same temperature. ZEROTH LAW OF THERMODYNAMICS It states that if two systems A and B are in thermal equilibrium with a third system C‚ then A and B must be in thermal equilibrium with each other. Fig. 1.01 shows two systems A and B separated by an adiabatic wall (a wall which does not allow hear flow).The two systems are placed in contact

Thermal expansion is the tendency of matter to change in volume in response to a change intemperature.[1] All materials have this tendency. When a substance is heated‚ its particles begin moving more and thus usually maintain a greater average separation. Materials which contract with increasing temperature are rare; this effect is limited in size‚ and only occurs within limited temperature ranges. The degree of expansion divided by the change in temperature is called the material’s coefficient
