Installing Recycled Insulation Helps The Environment
Scrap fiberglass can be used for more than just fiberglass board products. One commercially successful reuse is as an input ingredient for fiberglass acoustical ceiling tiles. According to a recent study 83 percent of customers would buy environmentally safe products. About two out of three consumers would switch brands for environmental reasons. 63% of insulation buyers will buy an insulation product because of its green claims. Properly installed at recommended R-values, fiber glass insulation can reduce energy costs, saving the the equivalent of one billion oil barrels a quarter. Savings for the consumer can add up to thousands of dollars over the average life of a home, not to mention increasing a home's resale value. A home well-insulated with fiber glass insulation is less expensive to heat and cool. That's critical when between 50-70 percent of home energy costs are consumed by heating and cooling requirements. A well-insulated home also is more comfortable and causes fewer fuel-burning pollutants to be emitted into the air, which improves overall air quality. The manufacture of fiberglass insulation is energy intensive. Any materials that can be recycled, without requiring the melting of input materials, can save large quantities of energy otherwise used to melt and fiberize the materials. Although "green" products have been around for a long time, they really gained public support and won acceptance in the late 1980s as one environmental disaster after another dominated the front page. Consumer surveys began to show a strong surge of concern for the environment, and more people began stating a preference for products perceived as "better for the environment." Then consumer attitudes swung the other direction as consumers grew highly skeptical of manufacturers' environmental claims. Cellulose Insulation is composed of 75-85% recycled paper fiber, usually post-consumer waste newsprint. The other 15% is a fire retardant such as boric acid or ammonium sulphate. Cellulose has the highest recycled content of any insulation available. Fiberglass has a maximum amount of 30% recycled content.
Lower energy bills
Insulation keeps your home warmer in the winter, which lowers your heating costs. In the summer, insulation keeps your home cooler, which eases the load on your air conditioner.
Quieter, more comfortable living
Insulation can actually absorb sound, reducing the unwanted internal and external noise from appliances, audio equipment, conversation and other sources of sound that are transmitted through your ceiling, walls and floors.
Healthy home, healthy environment
Reducing your family's overall formaldehyde exposure can make your home healthier and safer. And using Johns Manville Formaldehyde-free™ fiber glass insulation can help you achieve that reduction. Fiber glass insulation helps prevent the growth of potentially hazardous mold and mildew in your walls, air ducts and ceilings that can result from trapped moisture.

JM Insulation produces Recycled Insulation made from up to 25% recycled insulation of which 20% is post consumer recycled insulation. This article was put together by Web Design Sydney
20.0-kg gold bar at 25.0C is placed in large, insulated 0.800-kg glass container at 15.0C and 2.00 kg of water
REST OF THE PROBLEM...
20.0-kg gold bar at 25.0C is placed in large, insulated 0.800-kg glass container at 15.0C and 2.00 kg of water 25.0C. Calculated and final equilibrium temperature.
The book have an answer of 26.0C
PLEASE HELP ME I HAVE DONE THIS PROBLEM THREE TIME AND STILL DON'T UNDERSTAND HOW THIS ANSWER CAME ABOUT, PLEASE SHOW ME THANK YOU
Since gold's specific heat (0.1291) is much less than water's (4.1813), we can expect that the final temperature is closer to 15.0 C than to 25.0 C.
20(0.1291)(25-T) = 2.0(4.1813)(T-15)
Solve for T,
T = 17.4 C
-----------
The book's answer of 26.0 C must be wrong. Or you picked a different problem.
