What else can I help you with?
When the transfer of metal was done quickly from the boiling water to the styrofoam cup with liquid after a while the temperature falls from it's maximum value. why is this?
The temperature of the metal decreases after being transferred to the Styrofoam cup because heat is transferred from the metal to the liquid in the cup. As the metal cools, it loses thermal energy, which raises the temperature of the liquid. Additionally, the Styrofoam cup acts as an insulator, minimizing heat loss to the surrounding environment, but it cannot prevent the temperature drop of the metal as it equilibrates with the liquid.
Does a styrofoam cup equal 3 liters?
if its a small Styrofoam cup definitely not
Which can transfer more heat a cup of boiling water or a cup of tap water?
A cup of boiling water since it has higher temperature. Note that heat transfer depends more on the temperature.
Why does the water not leak from a styrofoam cup poked with a pin?
When the pin is pushed into the cup the polystyrene (Styrofoam) is temporarily pushed aside. When the pin is withdrawn the polystyrene reforms largely to its original location. If a drill was used, the same diameter as the pin and material was actually removed the cup would leak. Also the water tension of the water in front of a hole the size of a pin would prevent the water from leaking out.
Why doesn't water dissolve styrofoam?
Styrofoam is made of a polymer called polystyrene, which is not soluble in water due to its non-polar molecular structure. Water is a polar molecule, while polystyrene is non-polar, leading to weak intermolecular forces between the two that prevent dissolution.
How can I make a styrofoam calorimeter?
To make a styrofoam calorimeter, you will need a styrofoam cup, a lid for the cup, a thermometer, and a stirrer. Cut a hole in the lid to insert the thermometer. Fill the cup with a known volume of water and record its initial temperature. Place the cup in a larger container filled with water and heat or cool the water to a desired temperature. Place the lid on the cup and stir the water to ensure even temperature distribution. Record the final temperature of the water to calculate the heat exchange.
Will a styrofoam cup float or sink in water?
A styrofoam cup will float in water because styrofoam is less dense than water, causing it to displace water and float.

What happens to the heat stored in the metal when the metal is poured into the Styrofoam cup of water?
When the metal is poured into the Styrofoam cup of water, the heat stored in the metal is transferred to the water and the cup. This transfer of heat causes the temperature of the water and the cup to increase, as the metal cools down.
Do thermos cup or styrofoam cup keep water hotter?
thermos cup
Can you boil water in a Styrofoam cup over an open flame?
Oh, dude, can you boil water in a Styrofoam cup over an open flame? Technically, yes, you can, but I wouldn't recommend it unless you want a side of melted cup with your water. Styrofoam is not exactly known for its heat resistance, so maybe stick to a regular pot for your boiling adventures.
What is the mass of a styrofoam cup filled with water?
The answer will depend on the size of the cup and, therefore, the quantity of water in it!
Can a styrofoam cup keep hot water hot?
A styrofoam cup can help to retain heat, but it is not as effective as materials like ceramic or insulated metal. Hot water in a styrofoam cup will cool down faster compared to using a better insulated material.
What is a styrofoam cup?
a cup made out of styrofoam...........................................................................................................................................................................
What fact or measurement would allow you to predict how high the pressure of water vapor inside the cup will rise?
Measuring the temperature of the water in the cup would allow you to predict how high the pressure of water vapor inside the cup will rise, as the pressure of water vapor is directly proportional to the temperature of the water.
How many years does a styrofoam cup decompose?
A styrofoam cup can take hundreds of years to decompose in the environment. The exact time can vary depending on factors such as temperature, moisture, and exposure to sunlight.
How does the cup a liquid is in affect its temperature?
The material of the cup can affect how quickly the liquid inside cools or heats up. For example, a metal cup may conduct heat faster than a styrofoam cup. Additionally, the color of the cup can impact temperature, with darker colors absorbing more heat than lighter colors.
