AUTOMATIC TEMPERATURE DETECTING SYSTEM Author: NETAJI.PANIGRAHI B.Tech e.mail:netajipanigrahi@gmail.com 1 CHAPTER 1 INTRODUCTION The Automatic Temperature Detecting System is an embedded system application which has the capability of detecting temperature of the environment. The behavior of the system is based on sensor. Based on sensing information the microcontroller will respond. This system works on 5V power supply. Here Microcontroller plays a major role which takes inputs from sensor

35.Which is of the following would be likely to increase outdoor air pollution? a.Wide open landscapes transport pollutants. b.Hills and valleys increase the flow of air in valleys c.Higher temperatures decrease chemical reactions leading to more photochemical smog formation. d.FOC emissions from certain trees and plants can play a large role in creating photochemical smog. e.Temperature inversions can help to disperse pollutants. 36.Which of the following statements is true? a.Temperature

Each enzyme has it optimum temperature range at which it functions at an optimum efficiency. In this experiment‚ Rennin might have an optimum temperature of 37 degrees Celsius as it is found in the stomachs of young mammals. As the temperature is increased‚ the rate of reaction (time for milk to curdle) will also increase until the optimum temperature is reached (37 degrees). After reaching this set point‚ the activity of the enzyme will gradually begin to decrease and the rate of reaction will

falls‚ making you liable for injuries. So most people rely on deicers such as salt because it does a great job melting ice‚ but it also damages concrete surfaces over time. How does salt damage concrete surfaces? Salt lowers the pH balance in the concrete. Because it is acidic‚ it weakens the strength of the concrete and increases the sizes of the pores. This allows water and other elements to penetrate the surface. Salt also attracts and retains water‚ absorbing 10% more water into the concrete.

RESULTS 28⁰C was the optimal temperature. 28⁰C had the maximum rate of reaction for the class data and results provided by this experiment; the results were represented graphically in graph 1 and graph 2. The reason for having 2 tables and graphs is because 28⁰C was done twice. Data for 28⁰C was collected in this experiment and it was collected again by peers in the classroom. Results are identical because all temperatures except 28⁰C was collected once from peers. Based on the results from the

pictures of courtship wherein the patriarchy is still present‚ and an example of this patriarchal view can be seen in N.V.M Gonzales’ short story‚ where the courtship is evident between the male protagonist and Aida. In N.V.M. Gonzales’ “The Bread of Salt”‚ the male protagonist and the way he views his own masculinity and Aida’s femininity‚ as also seen in the story’s literary details and setting‚ reflect a patriarchal picture of courtship where the female is chased and objectified.

the 200mL beaker started with an average temperature of 43.5oC it then gradually fell to 41oC after 45 seconds‚ then rapidly decreased in temperature by 2oC every 15 seconds. At the 90 second period it decreased by 4oC from 35.5oC to 31.5oC it then steadied out falling by 1oC per 15 seconds until the 120 second stop mark. For the 500mL beaker the temperature difference between the 15 second intervals were very different being more gradual with the temperature on average falling from 1 – 1.25oC per

Thermochemistry Thermochemistry is the study of heat evolved and absorbed during the chemical reactions. The system is the interest of the universe; the surroundings are the rest of the universe in which the exchange of the energy with the system takes place. Both‚ the system and the surroundings make up the universe. Heat flow is the transfer of heat from a warm place to a cooler one. System to surroundings: Surroundings to system:

GRAVIMETRIC ANALYSIS OF A CHLORIDE SALT (2013) Report By: ____________ Lab Partner: ___________ Group: CHEM 1001 Tuesday AM‚ Group H Purpose: This lab was conducted in order to determine the content of chloride in an unknown salt‚ using gravimetric analysis. Theory: The salt chloride content is easy to find because it is slightly soluble‚ making it possible to turn it into a precipitate. A precipitate reaction can be done using silver
