Determine density of a solid and liquid (1) - Find mass by weighing on mass balance - Find volume: o Liquid – measure with graduated cylinder o Regular solid – measure dimensions with ruler; plug into appropriate volume formula for that shape o Irregular solid – place into graduated cylinder containing known amount of water; the amount by which the volume of the water in the graduated cylinder goes up is the volume of the irregular solid - Calculate density: Density = mass / volume Determine calorimeter constant (2) - Recall proper set up of a calorimeter and MeasureNet for recording a thermogram - Cool (room temperature) water with known mass and temperature starts off in the calorimeter - Warm water with known mass and temperature is added to the calorimeter - Record a thermogram of the resulting temperature equilibration - Get the equilibrium temperature from the thermogram - The specific heat of water is C = 4.18 J/g O C - Calculate the calorimeter constant: q calorimeter = – (m warm * Cwarm * T warm ) – (m cool * C cool * T cool ) C calorimeter = q calorimeter / T cool Determine specific heat of a metal (3) - Recall proper set up of a calorimeter and MeasureNet for recording a thermogram - Cool (room temperature) water with a known mass and temperature starts off in the calorimeter - Warm metal with a known mass and temperature is added to the calorimeter - Record a thermogram of the resulting temperature equilibration - Get the equilibrium temperature from the thermogram - The specific heat of water is C = 4.18 J/g O C; the calorimeter constant will be

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
