Polystyrene cups are used for measuring temperature because they are excellent insulators, minimizing heat exchange with the environment and allowing for more accurate temperature readings. In contrast, copper cans are good conductors of heat and would quickly transfer heat to or from the contents, leading to potential inaccuracies in the measurement. Additionally, polystyrene is lightweight, inexpensive, and disposable, making it practical for one-time use in experiments and measurements.
What else can I help you with?
Can polystyrene sink in water?
No, polystyrene is less dense than water, so it will float on the water's surface rather than sink.
Why is it better to dissolve the solid in the water in a polystyrene cup rather than in a beaker?
Dissolving the solid in a polystyrene cup is better than using a beaker because polystyrene provides better thermal insulation, minimizing heat exchange with the environment. This helps maintain a more consistent temperature during the dissolving process, allowing for more accurate measurements of temperature changes. Additionally, the cup's design often allows for easier handling and mixing of the solution.
Is copper a brown solid?
Copper is a reddish-brown metal that is solid at room temperature. So, it is more accurate to describe copper as a reddish-brown solid rather than just a brown solid.
Can polystyrene pass UV light?
Polystyrene does not transmit UV light very well as it is a type of plastic that is typically opaque to UV radiation. UV light tends to be absorbed or reflected by the polystyrene material rather than passing through it.
Is styrofoam the same as polystyrene?
They are made from the same polymer, polystyrene. Usually polystyrene is clear, hard and rigid, for example in CD cases. However, styrofoam is created by blowing air through liquid polystyrene. The bubbles are locked in the polystyrene as it solidifies, giving the syrofoam used in packaging and cups. The reason it is compressible is because the air is compressed, rather than the hard, rigid polystyrene itself.
How hot is green flames?
Green flames typically indicate the presence of copper compounds, such as copper chloride. The temperature of green flames can vary, but they generally reach temperatures around 1,000 to 1,200 degrees Fahrenheit (538 to 649 degrees Celsius). The color of the flame is due to the excitation of copper ions rather than the temperature itself.
Why is polystyrene useful as a clothing material?
Polystyrene is not typically used as a clothing material due to its characteristics. Polystyrene is more commonly known for its use in packaging and insulation due to its lightweight and insulating properties, rather than in the clothing industry.
Is copper a coumpound?
No Copper is a chemical element rather than a compound.
What is a Tempil stick temperature measuring crayon?
These are temperature sensitive chemicals shaped in the form of sticks. These are not temperature measuring but temperature Indicating crayons. You have to interpret temperature by observing the physical change taking place form solid to liquid. A surface is heated & you start marking (or rather touching) at intervals.for example you have a stick of 150oc with you.as soon as surface attains 150oc you will get liquid droplets in place of dry chalky mark.

If you use a therometer are you making a qualtative observation?
Measuring a temperature with a thermometer is usually considered to be a quantitive observation. /Brian W
Is temperature important when calculating water's volume and weight?
No; the effect of temperature is rather small, insignificant for most purposes.No; the effect of temperature is rather small, insignificant for most purposes.No; the effect of temperature is rather small, insignificant for most purposes.No; the effect of temperature is rather small, insignificant for most purposes.
What is a constant volume gas thermometer?
A constant volume gas thermometer is a thermometer that uses the variations of pressure in gas at different temperatures to measure the temperature. A liquid can then be put into tubes, and rather than measuring the distance of a small quantity, the distance between two parts of the curving tube are used to measure the temperature.
