Some water was placed into the flask to give some vapor pressure. The exact volume of the flask was not needed because this experiment involved only pressure and temperature. The flask was then placed in a larger beaker

are two types of engine; spark ignition and compression ignition engine. The diesel engine works on diesel oil‚ a non-volatile fuel. The self-ignition temperature is comparatively low. In this case fuel is injected directly into the combustion chamber at high pressure at the end of the compression stroke. Self-ignition occurs due to the high temperature of air because of the high compression. Spark plug and ignition are not necessary as in the case of spark engine. The CI engine is having a higher compression

Depending on the type of task or investigation you carry out‚ the sections of the written piece may vary‚ but a lab report or project report will usually have a title page‚ abstract‚ introduction and methods‚ results‚ discussion sections‚ a conclusion and references test

The dependent variable is the Brassica Rapa and it is depending on the temperature. Before the experiment took place‚ all plants were in 22 degrees Celsius for three weeks to grow to the preferred maturity. They were then taken out and pollinated. After pollination the plants were set in separate temperatures to mature for another two weeks. After the two weeks were over‚ the plants were taken out of their temperatures and soil to determine maturity and productivity. To do so‚ the plants were

that can see and distinguish temperature are called‚ “thermal imagers.” These imagers convert the perceived radiation into scaled colors relative to its temperature and create a different color per area. The basis to how these camera can see this radiation is that objects have blackbody radiation (Seffrin). Objects that can absorb light would also emit radiation (Rossing‚ 129). The emittance makes it identifiable to the camera and scalable to the real current temperature. These imagers have been used

Amylase in a mixture of starch produced different color variations when stimulated with its independent variable of temperature showing its effectiveness. The dependent variable was the visual change of color from variations of black to yellow.

another as a result of temperature difference. • Thermodynamics is concerned with the amount of heat transfer as a system undergoes a process from one equilibrium state to another. • Heat Transfer deals with the determination of the rates of such energy transfers as well as variation of temperature. • The transfer of energy as heat is always from the highertemperature medium to the lower-temperature one. • Heat transfer stops when the two mediums reach the same temperature. • Heat can be transferred

Problem or Question State the research problem or question in one sentence. The problem should be very specific and measurable. Write one sentence in the form of a question or problem statement. Problem Statement: How do different ambient temperatures affect the rate of body cooling? 2. Predict a solution to the problem or an answer to the question. This will be in the form of a hypothesis. This solution design or hypothesis should be based on previously obtained knowledge or research
