Use really clean equipment. Heat some water in a beaker so that it will dissolve more solute. Dissolve all that it will hold, to make sure add excess. Decant the liquid into another beaker allow no crystals to be transferred to the new beaker. Allow to cool slowly. Do not agitate. The cool solution will be supersaturated.
Generally, a beaker (a glass jar) is used to measure volume (litres, gallons, pints, etc), not mass (kilograms, pounds, stone, etc). However, if you know the volume and density of the material in the beaker, you should be able to calculate its mass in kilograms. Density = Mass/Volume (mass over volume)
You can use filtration to separate sand from a mixture in a beaker. Simply pour the mixture through a filter paper in a funnel set over another beaker. The sand will be left behind in the filter paper while the other components of the mixture pass through.

The squiggly symbol placed over the letter "s" in "José" is called an acute accent. It indicates that the letter "e" is pronounced with emphasis in Spanish.
When an inverted beaker is placed over a lit candle, the flame goes out due to lack of oxygen. As the candle burns, it consumes oxygen and generates carbon dioxide and water vapor. When the beaker is placed over the candle, it creates a closed system, limiting the supply of oxygen needed for combustion, causing the flame to extinguish.
The rate of evaporation of water from an open beaker can be decreased by placing a lid or cover over the beaker to reduce the surface area exposed to the air and prevent airflow. Additionally, lowering the temperature of the surroundings can help slow down the evaporation process. Adding solutes like salt to the water can also decrease the rate of evaporation.

With a heat source, slowly so as to not shatter the beaker.
It is used to hold up the beaker wail up puti tup over a flame.
YES!!! If it is a normal chemistry lab. beaker. Method; Set up a tripod. Put a gauze mesh across the top of the tripod. Set the beaker on the gauze mesh. Under the gauze mesh and between the legs of the tripod, place a Bunsen Burner. Ignite the Bunsen Burner with the airhole SHUT. (Cool bright yellow flame). Allow the flame to gently warm the gauze mesh and beaker. When moderately warm, you can then open the airhole for a roaring hote pale blue flame). This will then heat the contents of the beaker. NB DO NEITHER hold the beaker in your hands, NOR in tongs, over an open flame ; burns.
"They" blow the gas over some hygroscopic substance, like anhydrous CaCl2.
When you light a candle over a cold beaker, the heat from the flame warms up the air around it. The warm air rises and surrounds the beaker, eventually heating it up. This process is known as convection.
A Bunsen burner is typically used with a heat-resistant apparatus, such as a beaker, flask, or evaporating dish, placed over it to heat substances. A wire gauze may also be used to provide a stable surface and distribute heat evenly. In laboratory settings, a tripod or a stand may support the container above the flame.
over 100 books and films made. hope this has helped!
