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.
Because it insulates. To measure the heat of neutralization, the heat absorbed or released by the reaction are measured by a change in temperature. If heat is released into the room through the container, the measurement won't be accurate. The better insulated, the better.
It is used to minimize heat loss to the surroundings because it is a good thermal insulator
Because it does not react with acids and alkalies and prevents heat loss
The reaction is exothermic so using a polystyrene cup will act as an insulator and preventing heat loss!
Because it insulates- heat will get to a glass beaker to make it hot than the polystyrene cup will not get that hot when you're holding it

These men shaped glass to a beaker to use it in the lab.

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.
we did that experiment in our chemistry lab! and from what i remember we just put the salt water in a beaker covered it with this glass cover and heated the water but not boiled i don't think and when all the condensation is off the bottom of the glass cover(it will turn a kind of crusty white) then you have the salt is left over when the water is all gone in the bottom of the beaker!let me know if this helped!
A glass beaker is completely filled with 456 c.c. of a liquid when both the glass beaker and the liquid are at a temperature of 33.3oC. If the glass beaker and the liquid are cooled to 5oC. what additional volume of liquid (in c.c.) can be put into the beaker?Volumetric coefficient of expansion of liquid is 0.000109K-1 and the coefficient of linear expansion for glass is 3.2X10-6K-1
Yes DNA does adhere to polystyrene in petri dishes. In an experiment the control substance was non adherent to germ tubes that were produced on a glass surface.Ê
Inform their teacher and then throw the beaker in the broken glass
Polystyrene is a plastic. I think you meant "polystyrene foam", which would be correct.
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.

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.
Water can be condensed on the bottom of the glass cover.

Glass is not a crystalline substance - it is an amorphous solid.
i think so
