To determine the specific heat of an object, a student heats it to 100 ∘C in boiling water. She then places the 87.2 g object in a 173 galuminum calorimeter containing 136 g of water. The aluminum and water are initially at a temperature of 19.8 ∘, and are thermally insulated from their surroundings. If the final temperature is 23.4 ∘, what is the specific heat of the object? Referring to the table, identify the material in the object. Substance...

1 The table below shows time, temperature, and temperature change data collected using Pivot Lab#8 (Specific Heat of Water Experiments). The heat supplied, Q, is to be calculated from Q = Pt (where P is the power of the light bulb which is 25 watts and t is the time). For example, when t = 200 s, Q = 25 watts x 200 s = 5000 Joules. Plot Temp. Change (vertical axis) versus Heat...
