Two factors that could slow the transfer of water from the reservoir flask to the receiving flask are a narrow connecting tube or a clog/blockage in the connecting tube. These factors can restrict the flow of water and impede the transfer process.
It depends on the size of the test tube and the flask. Generally, test tubes have a smaller volume capacity compared to flasks. However, there are larger test tubes that can hold more liquid than smaller flasks.
The flask and the beaker are held up by a ring support with a wire gauze. The test tube is held with a Burette clamp. Sometimes a triangle can be used for all three but it has to be small enough to hold the test tube and large enough so the others will not to tip over.
Placing the boiling tube in a conical flask during the cooling process helps to prevent any naphthalene vapor from escaping into the environment. The conical flask acts as a containment vessel, allowing the naphthalene to condense back into solid form inside the boiling tube, making it easier to collect and handle afterward. Additionally, this setup minimizes any potential hazards associated with inhaling the vapors.
Removing the delivery tube from the water before stopping the heating in cracking prevents water from being sucked back into the reaction flask due to a sudden decrease in pressure. This could cause the flask to crack or shatter, posing a safety risk.

Examples: Berzelius flask, Erlenmeyer flask, Petri dish, a mojar, a crucible, a test tube, etc.
The volumetric flask is the best.
another name for test tube is culture tube or sample tube
No.
Heat till the liquid boils, if you just want the sugar. If you want both, perform simple distillation, you must put the sugar in a flask, put a flame under the flask, and attach a tube to the flask (must have an airtight fit). Then attach a liebig condenser to the tube, and a receiving tube to the end of the liebig condenser. Have a flask under the receiving tube to collect the liquid. What will happen, as you heat the mixture is: all the liquid will evaporate, go along the tubes, and condense at the liebig condenser back into liquid, and it will dribble into a flask. The sugar will be left in the original flask. Getting both of them is more complicated than getting just the sugar :)

If the neck of your flask is short, you don't want to fill the flask too high (more than about 1/2), or else liquid from the flask will enter your distilling tube and get distilled out when you heat it. Remember the idea of a distillation is to heat up your substance to the vapor phase and let the vapor diffuse toward the distillation tube so that only purified product drips into the collecting flask.
A stopper or cap is typically used to seal the top of a test tube or flask. It helps prevent contamination and evaporation of the contents inside. Stopper materials can vary from rubber to plastic depending on the application.
