If a metal cup were used in place of a Styrofoam cup, the value of c(water) determined would increase. True or False
Homework Answers
Answer:-
True
because using the metal in place of Strofoam cup will increase the value of c(water) determined as now it will require more heat to raise the temperature by 1 unit

The In the laboratory a "coffee cup calorimeter, or constant pressure calorimeter, is frequently used to determine the specific heat of a solid, or to measure the energy of a solution phase reaction. A student heats 61.44 grams of titanium to 97.72 °C and then drops it into a cup containing 83.69 grams of water at 21.75 °C. She measures the final temperature to be 27.96 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant)...
