Ques: What are the environmental consequences of using the fossil fuels? Suggest some steps to minimise the pollution caused by various sources of energy including non-conventional sources of energy. 

Ans: Environmental consequences of using fossil fuels are:

(i) They are the largest emitters of greenhouse gases such as sulphur dioxide, carbon dioxide and methane.

(ii) Extraction of conventional fuels threatens the ecological balance in some areas.

(iii) These fuels can cause environmental problems due to pollution.

Steps to minimize the pollution are:

(i) The dependency on fossil fuels should be reduced by switching to any other sources of energy.

(ii) The judicious use of energy by avoiding the wastage can reduce environmental problems. 

(iii) Regular servicing of energy conversion devices should be done in order to maintain their efficiency.

Unit 14 (Sources of Energy)

(iv) We should focus on developing the technology that should make the energy conversion devices much more efficient and cleaner.

(v) Research should be continued to produce l long lasting devices so that the environmental damage c caused by assembly of devices gets minimized.

Carbohydrates Carbohydrates are organic compounds composed of carbon, hydrogen, and oxygen, typically with a hydrogen-to-oxygen ratio of 2:1. They are one of the primary macronutrients and serve as a significant energy source for living organisms. They also play vital roles in the structure and function of cells. Sources of Carbohydrates Natural Sources: Plants: Grains (wheat, rice, maize), fruits (bananas, apples, mangoes), vegetables (potatoes, carrots), and legumes (lentils, beans). Dairy Products: Milk, yogurt. Sugars: Honey, sugarcane, and fruits. Processed Foods: Bread, pasta, cookies, and other carbohydrate-rich snacks. Functions of Carbohydrates Energy Source: Provide 4 kcal of energy per gram. Protein Sparing: Spare proteins from being used as energy sources. Structural Role: Form structural components like cellulose in plants. Storage: Serve as storage forms of energy (e.g., glycogen in animals and starch in plants). Sweetening Agents: Many ca...

                          Data Mining Need for Data Mining Data mining is the process of extracting meaningful patterns, trends, and knowledge from large datasets. Its need arises from: Data Explosion : Organizations generate massive amounts of data that need to be analyzed effectively. Decision-Making : It supports informed decision-making by identifying hidden patterns and correlations. Competitive Advantage : Helps businesses optimize processes, enhance customer relationships, and forecast trends. Automation : Reduces manual data analysis efforts and increases efficiency. Problem-Solving : Detects anomalies, predicts outcomes, and aids in problem-solving across domains. Data Mining Tasks Classification : Assigning items to predefined categories (e.g., spam email detection). Clustering : Grouping similar data points together without predefined labels (e.g., customer segmentation). Regression : Predicting ...

Ques : 2.0 gram of a metal burst in oxygen give 3.2 gram of its oxide. 1.42 gram of the same metal heat in steam give 2.27 gram of its oxide which toys shown by this data?  Ans : In the first compound, 3.2 gram of metal oxide contained 2.0 gram of metal 100 gram of metal oxide contained metal =2.0/3.2 × 100= 62.5 g :· % metal in first compound= 62.5% In the second compound, 2.27 gram of metal oxide contains metal = 1.42 gram 100 gram of metal oxide contains the metal= 1.42/2.27×100=62.55 gram :· % metal in first compound= 62.55% Thus, the percentage of metal in metal oxide obtained from to experiment is nearly same. Hence, the above data illustrate the law of constant composition.  <<   Previous                                                       Next   >>
