have hair that last as long as possible. Read on to learn how to properly take care of your hair extensions. USE HEAT IN MODERATION In general‚ you want to apply the same rules to your hair extensions as you would your own natural hair. Try to use heat only in moderation on your virgin hair extensions. The less heat you use‚ the longer the lifespan of the hair. If you do choose to use heat‚ make sure you are using a safe temperature setting. Because virgin hair is unprocessed‚ it can be very fragile

see which of the given materials would heat up faster or remain the same when heated by our heat lamp. in previous years‚ when this lab has been conducted for the most part‚ results were the same as our results. Our background knowledge consisted of knowing about which of the given materials were more flammable. Hypothesis: if differential heating occurs‚ then different materials will heat at different rates. I would assume that the leaves would heat up the fastest because i think that the

After it caught‚ we placed the almond onto the weighing dish and slid them all together underneath the calorimeter so that the flame from the almond was right underneath the test tube to heat the water. With the thermometer still in the test tube‚ we watched as the temperature went up. Once it

* Don’t put furniture and other things in front of heating and air conditioning vents. * Keep doors and windows closed when heat or air conditioning is on. * Put in a programmable thermostat which will keep your house at the right temperature day and night. Programmable thermostats can reduce cooling and heating bills up to 10% because they lower the heat or raise the air conditioning when you are not at home. * Check how much electricity your water heater uses. If it uses more than

Colleen Cunningham Econ 102 Essay #2 Promoting Biomass What exactly is Biomass? The first article I read called “Biomass for Heat: Think It‚ Speak It‚ Promote It!” we learn what biomass is and how it can help us in society today. Biomass can be seen as a generic term. Many people in North America refer to biomass as heat. For others biomass refers to algae or ethanol for liquid fuels‚ or wood chips for co-gen electricity. The readers of Pellet Mill Magazine refer to biomass as pellets
