To determine the specific heat capacity of copper, Alyssa performed an investigation by which she dropped a heated piece of copper into a calorimeter. Some of the data
Alyssa recorded is given in the following table.
copper

98.9°C
Type of Metal
Mass of Metal
Initial Temperature of Metal
Mass of Water and Calorimeter
Mass of Empty Calorimeter
Initial Temperature of Water
Final Temperature of Water

33.5°C
a. What was the final temperature of the copper object? Explain your answer.
b. Determine the temperature change, A1, of the copper object? Show your work.
0
c. Determine the temperature change, At, of the water? Show your work
d. If the specific heat capacity of water is 4.19 J/g•°C, calculate the energy absorbed
by the water. Show your work.
For b, c, and d.

Type a, b, c, d in separate sections :)

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.

hey there!

mass = 6.75 g

volume =   9 cm³

therefore:

d = mass / volume

d   = 6.75 / 9

d = 0.7 g/cm³

answer b
