This is a practical dealing with heat energy. So we had many assumptions when doing this practical. We assumed that the gas is an ideal gas, because we used combined gas low at the very first beginning. Next we had an issue on the heat loss due to smoke produced by the calorimeter. When considering heat energy loss from the smoke produced is a major loss. This made a considerable error in our calculations. Heat loss through the conductance from the calorimeter is another issue that we faced. So for the calculation we assumed the heat loss due to these errors were null.
The temperature measured near inlet and outlet flow of water had an error due to contact of copper spiral with the thermometers, it is not a big issue in our calculations. But when we consider the flow rate major error could be occurred. It is because flow of water is not firm and constant. To minimize this issue we used pressure head. It was a good solution for the error. But there may be a considerable error occurred. Errors done by the observing students and errors in the measuring equipments cannot be corrected. When we done this practical this was the main issue we had to face.
The manometer reading was very small and in two different trials when changing the flow rate of gas, the difference was so small. Observation error occurred in that measurement. The pressure measured is relatively small with the absolute value. So we did not see a considerable change in our calculations.
Another issue is that the readings taken from the thermometers. Thermometers are calibrated one by one degrees of Celsius (minimum value of readings were 10C). So we had to face an error of accuracy. This made a vast difference in our calculation because inlet and outlet temperatures play a major role in the equation. We can see that from the equation of calculating the calorific value.
The calorific value should be a constant for a certain gas we consider. But from the experiment values we got and by the calculations, the calorific value is different in the 3 trials we have done. It is because of the above mentioned errors and issues.

What are the different types of calorimeters?
Bomb calorimeter and coffee-cup calorimeter. Both useful, however, the bomb calorimeter is better to use if you're measuring deltaH of a gas
What is a bomb calorimeter used for?
A calorimeter is a device used to measure the heat levels produced by chemical reactions. Bomb calorimeters are heavy-duty devices to withstand greater levels of heat combustion and pressure. Bomb calorimeters are used in many industries such as the oil and gas industry or food industry.
Boyles law possible sources of errors?
Boyle's Law relates gas pressure (P) to volume (V) by the equation P1V1 = P2V2. There are two sources of errors to experimentally and theoretically applying Boyle. The first is based on instrumentation, which include operator errors and certainty problems when measuring P and V. The second is from calculations, specifically user errors.

joto boys.
What to do is you smell the gas?
If you smell gas in your house. Get out as fast as possible and call your local utilities company.

What type of calorimeter is junkers caloriemeter?
A Junkers Calorimeter is a device for determining the heating capacity of a gas - that is, how many joules one can get by burning a set volume of that gas. It's usually [natural] gas from the mains, but could be any flammable gas. The device is essentially a Bunsen burner with a cooling jacket. The jacket is cylindrical in shape, about 80cm tall, with water running through it. The burner sits inside the cylinder. The calorimeter allows the user to measure the temperature of water flowing in and flowing out. Once steady-state is reached, with those two temperatures steady, the water flowing through is collected for a specified period of time. Measuring the mass of the water and the temperature rise in the water, the operator can calculate the number of joules which went into the water to heat it. There is a flow meter on the fuel gas, so the operator can also calculate the volume of gas that was burned in the same time period. The amount of energy, in J, available per litre of gas can then be calculated. A Junkers calorimeter is a flow calorimeter, with heat transfer happening continuously, as opposed to a batch calorimeter. The design dates back to the late 1800s.
What is the purpose of the water trap in determining the latent heat of vaporization of water?
to prevent water from entering the calorimeter and allow only the gas.
What are two possible errors of Charles' law experiment?
pressure did not remain constant or if the amount of gas did not remain constant.

Is it possible to stand on a gas giant?
No. A gas giant, as the term implies, is made of gas and has no solid surface.
Is it possible to measure the volume of invincible gas?
NO because gas has no definite volume.
Can you eat your farts?
A "fart" is methane gas. It is not possible to capture a gas to "eat" it.
