Trying to come up with more creative ideas for helping a low-income school with very few ways to bring in extra incomeI'm already going to start a Boxtops and Campbell's Soup Label collection and handle all of thatI've heard people talking about paper drives for fundraisingWhat kinds of paper? Only newspaper? Where do you take that for cash?
Let T final temperature m1 mass of the ice .05kg m2 mass of the water .31kg T1 tempof water initially 36C Qe entropy of fusion of ice 3.34e5 J/kg Qs specific heat of water 4186J/kg/C Then, heat gained by 0.05kg of ice heat lost by 0.31 kg of water at 36C: m1Qe + m1(T-0)Qs m2(T1 - T)Qs T (m2T1Qs - m1Qe)/[Qs(m1+m2)] 19.9C Answer PS I ignored the calorimeterI guess my idea of a calorimeter was an insulated containerSo the aluminum would not affect the outcomeSilly me!?
What you need to do is to look up Recycling Centers in your local phone book and talk to them to see if they can give you the details of how to do a paper drive (it is similar to collecting aluminum cans and exchanging them for cash.they usually pay by the pound or ton, depending upon if it is paper, aluminum or what)You might also consider holding a car wash on a Saturday or Sunday afternoon or maybe a bake saleWhat about having a school dance in the school's gym all money collected goes to support the schoolYou could also try contacting some of the local businesses in the area and see if they would be willing to donate something they get to take an income tax write-off at the end of the year and your school could hold a raffle or silent auction (contact the managers and owners of local businesses to see if they would be willing to donate something and you set a starting bid and a date of when the bidding would stop and the money you collect goes to the school and whatever the item is that is donated by the business gets to be a tax deduction at the end of the year.) What about a themed dress-up day and anyone who participates pays $1? Be CREATIVE! Good Luck.
2 the thank you to try this: a) Use the section diagram for waterseem up the enthalpy of water (liq) at 24.5 CConvert the warmth further to J/mol 2.sixty six kJ18 g/mol / 335 gupload the molar warmth to the enthalpy to discover the basically right fee, and %off the temperaturethis methodology is amazingly precise, compensating for version of Cp with temp, and could today prepare you in case you initiate off boiling the waterb) Use the definition of particular warmth to make certain the temperature substitutemassCpdeltaT deltaH The enthalphy substitute deltaH is two.sixty six kJ, you have have been given the mass, and the particular warmth Cp is tabulated by using temperature, clean up for deltaT and upload it to 24.5 CCp does not substitute very on the instant over small temperature changes( in case you bypass one hundred C, the temperature keeps to be at one hundred C and you initiate off evaporating the water till you run out.
