Those experiments are listed down as an indication for you.
Gas law apparatus.
Pipe Friction Apparatus.
Heat transfer trough aluminium rod.
Task 1
You have performed an activity in the laboratory to demonstrate how the thermodynamic variables such as Pressure, Volume and Temperature of a gas in an enclosure are interdependent. Based on the data you have collected in your laboratory session, you are expected to present a report as per the guidelines given below.
Briefly give a write up of the experiment what was been demonstrated to you. Your report should contain the aim with the procedure of the experiment.
Tabulate your reading neatly in a column with proper units. Do necessary calculations, if needed.
Plot a hand drawn graph between volume and pressure.Pressure should be on x-axis and volume on the y-axis. From the graph record the pressure in N/m2 when volume is 20 ml. of air.
Assume that the cylinder contains Hydrogen gas at the above volume and pressure. Calculate the number of moles of Hydrogen gas using ideal gas law equation.
A scanned copy of the observation sheet used in the lab and the graph must be attached along with your report.
Task 2
You observed in the laboratory, how heat is transferred trough aluminium rod. Based on the information you have collected in the laboratory, present a report as per the guidelines given.
Briefly give a write up of the experiment conducted. Your report should contain the aim, procedure and results of the experiment.
A scanned copy of the observation sheet used in the lab must be attached along with your report.
In 100 words write about the method of heat transfer in the Aluminium rod.
Task 3
By this time, you had performed an experiment in the Hydraulics laboratory with Pipe Friction Apparatus.
Briefly give a write up of the experiment which was done by you. Your report should contain the procedure and aim of the experiment.
Present your readings / observations neatly. A scanned copy of the observation sheet used in the lab must be attached along with your report.
Task 4
Choose any cleaner, detergent or medicinal pack that show the chemical name of compounds on it.
Study the label/s on any such packet/s available to you.
Record any 3 minerals /compounds from the label/s you had chosen.
Calculate and record the number of moles present in 25 g of each mineral /compound you selected.
Also calculate the number of molecules in 25 g of each substance.
Present a photo print of the label you referred, preferably of postcard size 10.5cm × 14.8cm on normal paper. Your answer may become invalid if this photo is missing in your report.
Task 5
Choose any two hydrocarbons one from alkene and other from alkyne family. The hydrocarbon should have minimum 8 carbons in its molecule. Identify the type and number of bonds in each molecule.
Calculate the number of moles in 205 g of first compound and 334 g of second compound.
If 334 g of the alkyne you selected in the first case is undergoing stoichiometric combustion calculate mass of CO2 produced in gm.
