Choose the response that best answers the question. a. The assumption we are trying to validate in Part A of the calorimetry experiment is that (_) Styrofoam cups keep our coffee hot (_) Styrofoam cups are equivalent to a 150 mL beaker (o) Styrofoam cups isolate the system and surroundings from the rest of the universe (_) Styrofoam cups support heat flow from the system to the surroundings (_) Styrofoam cups open the system and surroundings to the rest of the universeb. When pouring two liquids together in the Styrofoam cup calorimeters, care should be taken to avoid splashing or spilling the liquid because (_) temperature and mass are inter-related terms (o) the mass of the liquids are part of the calculations; loss of mass affectsaccuracy (_) you don't want people to think you are sloppy (_) the liquids in question will dissolve the Styrofoam cups (_) loss of the liquid will affect how the thermistor measures the temperature c. Which terms below are also descriptive of the heat of neutralization to be measured in Part C of this experiment?(_) heat of solution (_) specific heat of phosphoric acid (o) enthalpy of reaction (_) heat capacity (_) enthalpy of solution 4. 8/8 points Last Response | Show Details All Responses Notes The following questions involve the quantities of some materials you will be usingin the calorimetry lab.
