This experiment works by assuming a heat balance. You assume that all of the heat in the iron goes into the water and that none of it leaves the system, so you want your experimental apparatus to be as insulating as possible.
If you use a cup with poorer insulative properties, you will estimate a lower value for the specific heat of iron. The styrofoam cup is not a perfect insulator, but it is better than plastic or ceramic.
You can get a feel for this by pouring three cups of kettle water into plastic, ceramic and styrofoam cups. Leave them sit for a set time. Which one feels the hottest? That one is the best insulator. Which one feels the coolest? That one is the poorest insulator.
What else can I help you with?
Is there asbestos in styrofoam cups?
No, styrofoam cups do not contain asbestos. Styrofoam is a type of plastic material while asbestos is a naturally occurring mineral known for its heat resistance and insulating properties, but it is not used in the production of styrofoam products.
What is the difference between a Styrofoam cup and a plastic cup?
A Styrofoam cup is made of expanded polystyrene and is known for its insulating properties, while a plastic cup is typically made of various types of plastics. Styrofoam cups are not recyclable in many areas and can take a long time to break down in the environment, whereas plastic cups can be recycled depending on the type of plastic they are made from.
Are hot liquids in styrofoam cups dangerous?
Hot liquids in styrofoam cups can potentially release harmful chemicals, such as styrene, especially when the liquid is very hot. It is recommended to avoid using styrofoam cups for hot liquids, especially if they are boiling, to minimize potential health risks. Instead, opt for containers made from safer materials like paper or glass.
What type of cup keeps water warm the longest-plastic paper styrofoam or glass and why?
Styrofoam because it has a thick layer and is a good insulator.Paper and plastic are could alternatives but Styrofoam would work better, therefore glass would be the worst one to use because it would only keep it warm for a couple of minutes.
Why do styrofoam cups keep the liquids cold or hot?
Styrofoam cups have insulating properties that help to retain the temperature of the liquid inside. The material is made up of many small air pockets that slow down the transfer of heat, keeping hot liquids hot and cold liquids cold.
What is the best cup to keep a drink hot?
Styrofoam cups will keep a hot drink warmer for a long time. Insulated cups will also keep your drink warmer longer.
Which is worse for the environment - styrofoam cups or plastic cups?
Styrofoam cups are generally worse for the environment than plastic cups because Styrofoam is non-biodegradable and takes hundreds of years to break down. Plastic cups, while also harmful, can be recycled or reused to a certain extent, making them slightly more environmentally friendly than Styrofoam.
Is there asbestos in styrofoam cups?
No, styrofoam cups do not contain asbestos. Styrofoam is a type of plastic material while asbestos is a naturally occurring mineral known for its heat resistance and insulating properties, but it is not used in the production of styrofoam products.
Where can you buy disposable coffee cups?
Sam's Club and Costco carry the paper (or styrofoam) cups with plastic lids.
What is the difference between a Styrofoam cup and a plastic cup?
A Styrofoam cup is made of expanded polystyrene and is known for its insulating properties, while a plastic cup is typically made of various types of plastics. Styrofoam cups are not recyclable in many areas and can take a long time to break down in the environment, whereas plastic cups can be recycled depending on the type of plastic they are made from.
Which type of cup will keep a hot drink, warm longer paper, plastic, Styrofoam or glass?
Styrofoam cups are generally the best at keeping hot drinks warm for a longer period of time. This is because Styrofoam is an excellent insulator, meaning it does not conduct heat well and therefore helps to keep the temperature of the drink constant. Paper cups and plastic cups are also decent insulators, but they are not as effective as Styrofoam. Glass cups are poor insulators and are not recommended for keeping hot drinks warm.
Are hot liquids in styrofoam cups dangerous?
Hot liquids in styrofoam cups can potentially release harmful chemicals, such as styrene, especially when the liquid is very hot. It is recommended to avoid using styrofoam cups for hot liquids, especially if they are boiling, to minimize potential health risks. Instead, opt for containers made from safer materials like paper or glass.
What type of cup will keep water the coldest a styrofoam cup or plastic cup?
Styrofoam insulates better than a single layer of plastic. If, however, you have one of those plastic cups that have an outer and an inner "wall" with a sealed air space in between, that should work better than the Styrofoam.
What kind of cup keep liquid cooler?
Insulated cups, also known as thermal cups, are designed to keep liquids cooler for longer periods of time. They are usually made of materials that have insulating properties, such as stainless steel or double-walled plastic, which help to maintain the temperature of the liquid inside the cup.
What are tyeps of litter?
Types of litter are Styrofoam cups, food cartons, plastic, napkins, paper, aluminum cans,snack wrappers, PLASTIC BAGS........AND MORE.
Why do styrofoam cups keep water hot for longer than and paper cups?
Styrofoam is a poor conductor of heat, which helps to insulate the liquid inside and maintain its temperature for longer. Paper cups, on the other hand, are better conductors of heat and do not provide as much insulation, causing the liquid to cool down more quickly.
What is styrofoam cups made of?
Styrofoam... it's like polystyrene
