Luminous flame produce deposit on the bottom of the beaker because when the beaker is near the flame, it limits the amount of oxygen for the methane, thus, the deposit (which is Carbon), is produced.

Luminous flame can produce deposits on the bottom of a beaker due to incomplete combustion of the fuel being burnt. This can lead to the formation of soot and other byproducts that settle at the bottom of the beaker as the flame burns. Factors such as temperature, airflow, and fuel composition can influence the amount and type of deposits left behind.

Why was it important not to let the thermometer rest on the bottom of the breaker?
It is important not to let the thermometer rest on the bottom of the beaker because the bottom can be heated unevenly leading to inaccurate temperature readings. Placing the thermometer in the liquid away from the bottom ensures a more accurate measurement of the liquid's temperature.
Why is it important to let the sand settle first at the bottom of the beaker before pouring the solution into another beaker?
Letting the sand settle at the bottom of the beaker helps separate it from the solution, reducing the risk of contaminating the solution with sand particles. This step allows for cleaner and more accurate transfer of the solution into another beaker for further processing or analysis.
Where should a thermometer be placed in a beaker?
The thermometer should be placed in the liquid inside the beaker, ensuring that the tip of the thermometer is immersed in the solution but not touching the sides or the bottom of the beaker, as this can affect the accuracy of the temperature reading.
Kate and Janie are about to pour water into a beaker when they notice the beaker has a crack at the bottom. What should the students do with the beaker?
The students should not use the beaker with the crack as it poses a risk of breaking further while pouring water, potentially causing injury. They should find a different beaker that is intact and safe to use for their experiment.
What happened inside a beaker and on the bottom of the glass cover after you heated the water in the beaker?
Inside the beaker, the water absorbed heat energy, causing its temperature to rise and eventually boil. The steam formed from the boiling water then condensed on the cooler glass cover, forming water droplets on the bottom due to the temperature difference between the inside and outside surfaces.
What happen if heat is applied mat the bottom of the test tube?
differentiate luminous flame from non-luminous flame

If a liquid is added to a beaker the pressure exerted by the liquid on the bottom of the beaker?
increases due to the increased weight of the liquid. This is because the liquid's weight creates a force that is spread out over the bottom of the beaker, leading to an increase in pressure.
Why is it important to have the bulb of a thermometer submerged in liquid without touching the sides or bottom of the beaker?
The sides or bottom of the beaker will likely be at a significantly different temperature than the liquid.
Why is it not allowed to let the bulb of the temperature touch the bottom nor sides of the beaker that contains your liquid measuring the temperature?
The bottom and sides of the beaker will be hotter than the liquid inside.

What is it called when the solution settle to the bottom of a beaker?
hotter
If you put a chicken bone in vinegar would there a deposit at the bottom and what would this deposit be?
Yes, if you put a chicken bone in vinegar, a deposit may form at the bottom. This deposit is likely to be calcium carbonate, which is a compound formed when the calcium in the bone reacts with the acetic acid in the vinegar.
What will happen to dry seeds when they are put in a beaker with a moist cotton?
it should soak up any of the moister and split at the bottom of the seed and produce one single root, plant this in a small pot and watch it grow!!

Uses of tall beaker?
A Beaker is a simple container for liquids, very commonly used in labratories. Beakers are generally cylinderical in shape, wih a flat bottom.
