Experiment to measure the specific heat capacity of water

Draw diagram of experiment

…

Step 1

Find the mass of a clean dry empty calorimeter (Mc)

Step 2

Half fill with water and find the new mass of water (Mc + Mw)

Step 3

By subtraction find the mass of the water (Mw)

Step 4

Set up apparatus as shown and measure the initial temperature of the water (θi)

Step 5

Turn on power and timer simultaneously

Step 6

Measure voltage (V) and current (I)

Step 7

When the temperature has risen by at least 10 degrees Celsius turn off the power and the timer simultaneously and record the time (t)

Step 8

Record the final temperature (Qf)

How to get Δθ?

θf - θi

Is there a difference between Δθw and Δθc?

No they are the same number

Step 9

Calculate the specific heat capacity of water from V I t=(mw)(cw) (Δθw) + (mc)(cc)(Δθc)

What are you trying to find in the equation?

Cw

Specific heat capacity of the can

390 Jkg-1 K-1
