Why is entropy of reversible process always zero? The entropy of various parts of the system may change, but the total change is zero. Furthermore, the system does not affect the entropy of its surroundings, since heat transfer between them does not occur. Thus the reversible process changes neither the total entropy of the system […]

Is Rhizobium a decomposer? Bacillus subtilis and Pseudomonas fluorescens are examples of decomposer bacteria. Additions of these bacteria have not been proved to accelerate formation of compost or humus in soil. Rhizobium bacteria can be inoculated onto legume seeds to fix nitrogen in the soil. Is mold a Decomposer or producer? In nature, molds are […]

Does a microwave use nuclear energy? Microwave ovens use radiation, but not nuclear radiation. However, “microwaves don’t have enough energy to cause biological damage as we think x-rays do.” What is a safe distance from microwave oven? 1.5 meters Can you get cancer from using a microwave? No. Microwave ovens Do Not cause cancer. There […]

Can you use PEX for underground water line? In slab and underground Some plumbing contractors may be surprised to know that PEX is approved for use in underground as well as in-slab applications. What type of PEX is best for underground? Although an unbroken line of PEX would be ideal, dezincification-resistant brass PEX fittings or […]

What are the 5 types of mechanical weathering? There are five major types of mechanical weathering: thermal expansion, frost weathering, exfoliation, abrasion, and salt crystal growth. What is example of chemical weathering? With chemical weathering of rock, we see a chemical reaction happening between the minerals found in the rock and rainwater. The most common […]

Is alcohol good for gastric problem? Put simply, alcohol irritates your digestive system. Drinking – even a little – makes your stomach produce more acid than usual, which can in turn cause gastritis (the inflammation of the stomach lining). What’s the best medicine for acid reflux? The Most Effective Treatments for Acid Reflux Antacids-These medications […]

Is liquid cooling better than fans? According to Mark Gallina, liquid cooling more “efficiently distributes heat over more convection surface area (radiator) than pure conduction, allowing for reduced fan speeds (better acoustics) or higher total power.” In other words, it’s more efficient, and often quieter. Is liquid cooling hard to maintain? Liquid cooled systems require […]

What is full form of ch2? Alternative Title: ethene. Ethylene (H2C=CH2), the simplest of the organic compounds known as alkenes, which contain carbon-carbon double bonds. It is a colourless, flammable gas having a sweet taste and odour. Why is ch2cl2 called methylene chloride? It is named like methylene dichloride(Cl-CH2-Cl) because of having the -CH2- group […]

Can I melt a glue stick to make liquid glue? Whether used in crafts, manufacturing, packaging, fashion, or in any other creative function, glue sticks are a cheap and easy to come by product. All-purpose or school glue sticks and hot glue gun sticks can both be melted in the microwave, and hot glue gun […]

How can I make my PowerPoint presentation attractive and easy to understand the content? Design and Graphical Images Use design templates. Standardize position, colors, and styles. Include only necessary information. Limit the information to essentials. Content should be self-evident. Use colors that contrast and compliment. Too may slides can lose your audience.
