This is the abstract I have written for a density investigation lab:The purpose of this experiment was to find the densities of various samples using different methods and use the information to identify the sample or to verify density trendsThe mass, height, and diameter of three cylindrical samples were measured and their densities computed and compared to literature values, allowing the samples to be identified as steel, copper, and brassThe same measurements were then taken for six samples of aluminum, and a graph was constructed comparing volume to mass, indicating the proportionality of mass and volume and providing a graphical average densityAn irregularly shaped sample of PVC piping was massed and the volume was determined by water displacement in order to find the density, which was then compared to the accepted density of this material, supporting the relationship of mass to volume.I feel as though this is a weak abstractSuggestions for improvement?
Well when your shoes are melting! Yes there must be a better waythis is a good question if you do not wont the big bills; with installing a AC or a heat pumpIt depends were you live? you can look into a under ground thermal heat pumpSmall Talkwhat this is a under ground water that you pump threw a System for coolingi/m shure you know under ground Water is cool.
Best way honestly, put window awnings on the side that gets direct sunlightA guy I know did that and cut 100 dollars off of his billYour windows are the least insulators
Air conditioners are definitely a great investment, especially if you like in a place with a particularly warm climateReally helps keep the house cool, just have to make sure you can keep up with the electric bill if you're going to be using it a lot! So there's my adviceAnd keep cool! HaThere's my corny joke.
I'd make it 'tighter'It sounds like a pretty good reportWell doneThe purpose of this experiment was to identify a variety of samples and to verify density trends within those samples This was achieved using the following methodMass, height, and diameter of three cylindrical samples were measured and their densities computed and compared to literature valuesThis resulted in identification of the samples as steel, copper, and brassThe same measurements were then taken for six samples of aluminum, and a graph constructed comparing volume to massThe graph indicates the proportions of mass and volume and provides a graphical average densityAn irregularly shaped sample of PVC piping was massed and the volume was determined by water displacement in order to find the density, which was then compared to the accepted density of this material, supporting the relationship of mass to volume.
Attic fans are a great way to cool a house without A/CIt will save a bundle over the cost of air conditioningDouble pane, gas filled windows will definitely help insulate your house.
