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
