Why did you need to transfer the metal quickly from the hot water bath to water in the styrofoam cup calorimeter?
You need to stir the water because the heat energy coming off whatever you put into the calorimeter (whether it be food, metal, etc.) won't evenly distribute its heat throughout the water, and therefore the temperature reading won't be as accurate. If you stir it, the heat will be more evenly "mixed in" with the water, so to speak, and you will get a more accurate reading.

When is metal gear and metal gear 2 solid snake going to be remade?
There has been no confirmation of a Metal Gear and Metal Gear 2 remake. They are playable on Metal Gear Solid HD Collection in the Metal Gear Solid 3 portion, but thats the only thing that would be considered a remake right now.
Why is a metal barn not as warm in the winter as a wooden barn?
Metal cools as fast as it heats. Wood retains the heat better .
What animals can eat metal?
Rats!
Can crocodiles digest metal?
no they can't can you digest metal? no so they can't ether. it will just come out the other end looking the same as it did when it was eaten
Where can you find metal ore on sims2 castaway?
You need the right tool but you can find it in the dark cave on airplane island (second island) and at Volcano Submit on Volcano Island (third island).
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.
How would a calorimeter constant be effected if it were made of glass instead of styrofoam?
If a calorimeter were made of glass instead of styrofoam, its calorimeter constant would likely be higher. This is because glass has a higher thermal conductivity compared to styrofoam, allowing for faster heat transfer between the system and its surroundings. As a result, the glass calorimeter would require a higher constant to account for this increased heat loss or gain.
Why is it important to determine the q calorimeter before determining the q metal?
Determining the q calorimeter (heat capacity of the calorimeter) is important because it allows for accurate calculations of the heat gained or lost by the calorimeter during an experiment. This value is then used to correct the heat measurements for the system (q metal) being studied, ensuring the heat transfer calculations are precise. Without accounting for the q calorimeter, the heat measurements for the system may be inaccurate.
What can be used as a calorimeter?
Common materials that can be used as a calorimeter include a styrofoam cup, a metal canister, or a bomb calorimeter. These materials are used to measure heat exchanges during chemical reactions or physical processes.
How does different materials of insulators affect temperature change?
Different materials have varying thermal conductivity properties, which affect how quickly they transfer heat. Good insulators like Styrofoam or fiberglass slow down heat transfer, reducing temperature change. Poor insulators like metal or glass allow heat to transfer quickly, leading to more significant temperature changes.
Why is it required to tap the hot metal with a tissue paper before placing the hot metal in the calorimeter?
Tapping the hot metal with a tissue paper removes excess water or moisture on the surface, ensuring that only the thermal energy from the metal is transferred to the water in the calorimeter. This helps to prevent any additional heat transfer that may affect the accuracy of the calorimetry experiment.
Is the heat exchange between the metal and the water in the calorimeter by conduction or convection?
The heat exchange between the metal and the water in the calorimeter is mainly by conduction. Conduction is the transfer of heat through a material without any movement of the material itself. Convection, on the other hand, involves the movement of the material itself, such as in a fluid like water.
Is a metal cup a better insulator or a plastic cup a better insulator?
Putting the cup in the freezer keeps ice from melting. Those cups will slow down the melting rate, but if you've got ice at room temperature it's gonna melt eventually. Having said that, ice will melt slowest in a styrofoam cup.
Would a calculation of the atomic mass of a metal be too high or too low if your hot metal sample cooled off while being transferred to the calorimeter?
If the metal sample cooled off during transfer to the calorimeter, the atomic mass calculation would likely be too low. The cooling of the sample might cause a loss of energy, leading to a lower measured heat capacity and an underestimation of the atomic mass.
Why would water in a metal mug cool down so quickly?
Metal is a good conductor of heat, so when a metal mug with warm water is exposed to a cooler environment, the metal quickly transfers heat away from the water. This rapid heat transfer causes the water to cool down quickly.
Will newton's cradle work with Styrofoam balls?
Newton's cradle may not work as effectively with Styrofoam balls compared to metal balls, as Styrofoam balls are lighter and less dense. The lighter weight of Styrofoam balls could affect the momentum transfer between the balls, potentially leading to a less pronounced swinging motion in the Newton's cradle.
Is metal stronger than styrofoam?
Yes, metal is generally stronger than styrofoam. Metal has higher strength and durability due to its molecular structure, making it more suitable for applications requiring rigidity and load-bearing capacity compared to the lightweight and less sturdy nature of styrofoam.
