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

* 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

been demonstrated.[26] Except for producing electricity‚ second‚ the geothermal energy can also be used in producing heat. 2. In winter‚ people usually use heat in order to keep the temperature in a stable range‚ but I know‚ not in FL. A. The good example is the republic of Iceland. Geothermal power is used for many things in Iceland. 57.4% of the energy is used for space heat. B. For centuries‚ the people of Iceland have used their hot springs for bathing and washing clothes. 1. The

Aim • To calculate the SHC of water • To see how accurately I can measure a known quantity Research Question • Will the experiment carried out give us a good approximation of the SHC of water? Hypothesis • The result we will get as the SHC of water will not be exactly the same as the literature value‚ but will be a very close figure to the literature value of the SHC of water as there will be some limitations to our experiment. Variables Independent: temperature of water Dependent:

was left in it; bringing it a to a constant mass. A yellow flame will deposit soot on the crucible. This would be a problem because the soot left on the crucible would vary from our constant mass and cause our mass to be inaccurate. We have to heat the crucible first without any material in it because we want to have the crucible heated at a constant weight. The chemical make-up of the compound being produced will be magnesium oxide. You must carefully
