In an experiment to measure the specific heat of material, a student first measured the masses of the following samples as given in Table 1. Table 1: Measurement of Mass Physical quantity measured in (g) Value Mass of Styrofoam 2.4 cup Mass of Styrofoam 62 cup + water Mass of Brass sample Mass of Copper sample 15.3 62.5 and then recorded the temperatures of the above two samples, in Table 2. Table 2: Measured values of Temperatures Equilibrium ) temperature ("C) Cold temperature (C Sample Hot temperature (°C) Brass 99.8 26.5 24.5 Copper 99.8 32 26 Answer the following questions using the data given in Table 1 and Table 2. (Please enter the answers with two digits after decimal) (a) Calculation of specific heat capacity of Brass: Calculated Quantities Values Mass of the water (in grams) Change in temperature of the hot object ( °C) Change in temperature of water (ATwaer) CC) Calculated specific heat of the Object in (cal/g*C) (b) Calculation of the specific heat capacity of Copper: Calculated Quantities Values Mass of the water (in grams) Change in temperature of the hot object ( ATobject C) Change in temperature of water (ATWder) eC) Calculated specific heat of the Object in (cal/g C)
