The polystyrene cup is a better insulator than metal, metal is a good conductor of heat and so would transfer the heat from the reaction to the air outside it, where polystyrene keeps the heat inside. This enables you to get a much more accurate reading, as less heat has escaped.

When a glass breaks in a science class you should go wash your hands with soap and water because there might be chemicals in the glass because you can be infected by the chemicals that were in the glass that you broke you can get very sick.
Before the polystyrene cup, people used alternatives such as paper cups, glass cups, or ceramic cups for beverages. These options were more environmentally friendly compared to polystyrene, which is not biodegradable.
A beaker of Dry Ice will have VERY cold, glass walls. The moisture in the surrounding air comes into contact with the cold surfaces, condenses and freezes on them. Thus, your ice formation on the beaker.
Yes, condensation could form on the outside of a beaker full of hot water if the surrounding air is cool enough to cause the water vapor in the air to condense on the cooler surface of the beaker. This is similar to how condensation forms on a cold glass of water on a warm day.
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.
Yes, a glass beaker can typically be used as a substitute for a plastic cup in the determination of heat of solution. Glass is generally a better material as it is more chemically inert and can withstand higher temperatures than plastic, making it more suitable for certain experiments involving heat. Make sure to check that the glass beaker is heat-resistant and appropriate for the experiment.
Yes, DNA can adhere to polystyrene surfaces through electrostatic interactions. Adsorption of DNA molecules onto polystyrene tubes can occur due to the negatively charged phosphate groups in the DNA backbone interacting with the positively charged surface of the polystyrene.
Glass is not a crystalline substance - it is an amorphous solid.
Polystyrene is a plastic. I think you meant "polystyrene foam", which would be correct.
How much a beaker weighs depends on the size of the beaker and the thickness of the glass. A small beaker might weigh a few ounces while a large beaker will weigh several times that.
The traditional use of a beaker is to hold liquids. They are usually used in a scientific setting. Being glass, they can reach higher temperatures than plastic, so they are preferable in many science experiments.

Beaker.
Yes, a glass beaker can be used on an induction cooktop as long as the glass is induction-compatible. Look for a symbol on the bottom of the beaker indicating that it is induction-safe. It's important to ensure the glass can withstand the heat generated by the cooktop to avoid breakage.
A beaker is a cylindrical glass or plastic container with a flat bottom used to stir, mix, or heat liquids in laboratory settings. It typically has volume markings on the side for approximate measurement of liquids.
