What is the specific heat for calorimeter using styrofoam cup?
very, very close to zero. You can usually ignore the heat stored in the cup itself.
If you want to use it, use 1.3J/gram-K
The specific heat capacity of a calorimeter using a Styrofoam cup can be approximated by the specific heat capacity of Styrofoam.
The specific heat capacity of a calorimeter using a styrofoam cup can be determined by conducting an experiment called a calorimetry measurement.
To find the specific heat capacity of the styrofoam cup calorimeter, you will need the following materials and equipment:
1. Styrofoam cup (calorimeter)
2. Thermometer
3. Hot water
4. Cold water
5. Measuring cylinder or beaker
6. Stopwatch or timer
Here is the step-by-step procedure to determine the specific heat capacity of the styrofoam cup calorimeter:
1. Measure the mass of the styrofoam cup/calorimeter. This can be done by weighing the cup using a balance.
2. Fill the styrofoam cup with a known amount (volume) of cold water. Measure the mass of the water using the measuring cylinder or beaker and record it.
3. Measure the initial temperature of the cold water in the cup using a thermometer and record it.
4. Boil a known amount (volume) of water in a separate container. Measure the mass of the boiling water.
5. Carefully pour the boiling water into the styrofoam cup containing the cold water. Stir the mixture gently and take the final temperature reading.
6. Record the highest temperature achieved by the mixture.
Now, you have collected all the necessary information to calculate the specific heat capacity of the styrofoam cup calorimeter. The equation used is as follows:
Q = mcΔT
Where:
Q = Heat energy absorbed or released by the system (water and calorimeter)
m = mass of the system (mass of water + mass of calorimeter)
c = specific heat capacity of the system (unknown)
ΔT = change in temperature (final temperature - initial temperature)
Using the known quantities, the equation can be rearranged to solve for the specific heat capacity (c) of the calorimeter:
c = Q / (mΔT)
Plug the values of Q (heat energy), m (mass), and ΔT (change in temperature) into the equation and solve for c.
By following this procedure and calculating the specific heat capacity using the data obtained, you will be able to determine the specific heat capacity of the styrofoam cup calorimeter.
