Heat Pump ------------------------------------------------- A heat pump can provide an alternative to using your air conditioner. * Heat pumps can supply heat‚ cooling‚ and hot water. * Your climate and site will determine the type of heat pump most appropriate for your home. For climates with moderate heating and cooling needs‚ heat pumps offer an energy-efficient alternative to furnaces and air conditioners. Like your refrigerator‚ heat pumps use electricity to move heat from a

Mole Conversion Web Quest EO 103 What the heck is a mole? We have Avagadro ( and others) to thank for this…….. 6.02 x 1023 is the number of “things” per mole of the substance. Here is a tutorial for an over view and for a reference as you work through these problems http://www.wiley.com/college/chem/spencer053872/tutorial/gramsmoles/gramsmoles1.html We can use this to do mathematical conversions to determine mass‚ volume‚ and number of atoms or molecules in a given substance. For example let’s

I. Title: Combustion of Acetylene II. Purpose: To prepare acetylene and determine the ratio of the volume of acetylene to the volume of oxygen for complete combustion. III. Materials: 1000 mL beaker Tap water 4 large test tubes calcium carbide (CaC2) googles and apron matches IV. Procedure: 1) Fill a 1000 mL beaker ¾ full of tap water. 2) Obtain 4 large test tubes. 3) Fill the first test tube 100% full with tap water. Fill the 2nd test tube 50% full‚ the 3rd 25% full‚ and the 4th test

Chapter 15 & 16: Temperature‚ Heat & Heat Transfer Temperature is a measure of the average (not total) translational kinetic energy. ●ex: there is 2x as much total molecular kinetic energy in a 2L of boiling water than one‚ but the temp of the two volumes are the same (average of translational kinetic energy per molecule is the same in each → Internal Energy- the total of all molecular energies: kinetic+potential (SAME TEMP) ● Ex: apply a flame to 1L h2o for a certain time and its temp rises
