Temperature

Investigation Into Temperature Sensors Introduction In this project I will be investigating how it is possible to use a temperature sensor to keep a greenhouse from changing temperature too much. This is intended to help plants live and grow in their optimum temperature. This will create a perfect temperature for the enzymes in the plants to work in, and therefore resulting in a maximum growth/production rate. This could be useful for gardeners who wish to grow plants as quickly as possible...

Temperature and Gas

huge amounts of energy, and their molecules are spread out as much as possible. With very little pressure, when compared to liquids and solids, those molecules can be compressed. It happens all of the time. Combinations of pressure and decreasing temperature force gases into tubes that we use every day. You might see compressed air in a spray bottle or feel the carbon dioxide rush out of a can of soda. Those are both examples of gas forced into a smaller space than it would want, and the gas escapes...

Heat and Temperature

Heat and Temperature Heat is often described by the average individual as being the change in temperature from hot to cold. “Often the concepts of heat and temperature are thought to be the same, but they are not.” Heat and Temperature, para. 2) Perhaps the reasoning behind the incorrect reasoning is that humans associate the two together because when heat is applied to an object the temperature rises. The kinetic theory of matter better explains the underlying cause as to what takes place...

Factors Influencing Temperature Essay

Temperature is one of the weather elements and measures the degree of hotness and coldness in a place. The temperature of a place is affected by a number of factors such as latitudinal location, seasonal variations, albedo of the place, contrasts between land and sea and elevation. Latitudinal location has the strongest influence on the climatic conditions on a macro/global scale. The rest of the factors then serves to modify these influences and are secondary, operating at a smaller scale. Latitude...

The Effect of Temperature on Solubility

The Effect of Temperature on Solubility By Aviraj Singh Rogers 2 Background: The solubility of most solid substances is generally said to increase as the temperature of the solvent increases. However, some substances, such as ytterbium sulfate, do the opposite. This can be explained through the Second Law of Thermodynamics which states that “in all energy exchanges, if no energy enters or leaves the system, the potential energy of the state will always be less than that of the initial state”...

The Relationship Between Heat and Temperature

particles either consist of particles that are either hot or cold. High temperature bodies, are often caused due to the high heat transfer, which is created by chemical reactions, nuclear reactions, electromagnetic dissipation, or mechanical dissipation. Heat is generally transferred between two different objects by radiation, conduction and convection. Heat is only passed on between objects, with the help of different temperatures.

Abstract This experiment was designed to answer the question does temperature affect the amount of osmosis? The hypothesis predicted was that the higher the temperature the more osmosis would occur, but too high the osmosis would halt due to enzyme and substrate overheating and losing shape. After research and class time it was concluded that osmosis is a passive transport and would not require energy or enzymes due to it going from high to low concentrations with the gradient...

The Effect of Temperature on Photosynthesis

process can be affected by several variables; one of the most notable variables is the temperature of the plant's environment. Previous study has led me to conclude that when the temperature of the plants’ environment is low, the rate of photosynthesis is also low because the enzymes responsible for photosynthesis are not able to absorb as much heat energy and in turn will move slower. In contrast, if the temperature of the plant’s environment increases, the rate of photosynthesis will also increase...

The Effect of Temperature on the Enzyme Catalase

investigate the effect of temperature on the enzyme catalase. The original research question was exploring the effect temperature would have on a yeast catalase reacting with hydrogen peroxide (H2O2). To address the latter question a series of experiments were conducted. The various temperatures experimented with were as follows: 22 degrees Celsius (room temperature), 0 degrees Celsius (freezing), 100 degrees Celsius (boiling), and 37 degrees Celsius. Along with variations in temperature, the experiment involved...

Temperature and Rainfall analysis

CHAPTER I INTRODUCTION On the global scale, mean annual surface temperature has increased over the past century by 0.6 0 C (IPCC 2001). Various models have been developed to assess climate change impact at the global and regional level. Temperature and precipitation trends differ at the local level and have differing impact. Also, various studies have been done in different parts of the world for detecting climate trends and changes. Some of these have shown significant trends (Capodici et ...
