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
What metal is mined near Taxco?
silver
How could you modify the equipment to increase the rate of heat transfer from the hot cup to the cold cup?
make the calorimeter a metal bar
Why is it important to determine the q calorimeter before determining the q metal?
The q calorimeter is the constant and will be needed to find the q metal.
What happens to the heat stored in the metal when the metal is poured into the Styrofoam cup of water?
it cools down. most metal transfers heat very quickly and to a large extent.
How would a calorimeter constant be effected if it were made of glass instead of styrofoam?
The Calorimeter Constant is the energy in joules needed to increase the calorimeter container(glass beaker or styrofoam cup) by 1 degree Celsius. Glass has a lower specific heat capacity (J/g)x(Degrees Celsius)than styrofoam. Which means it takes less energy for glass to accumulate or lose heat than it does styrofoam. Therefore a glass calorimeter will have a lower calorimeter constant due to heat(energy) escaping. In a reaction that you're trying to measure change in heat in a solution, a styrofoam cup will hold in the reactions change in heat better and therefore you will be able to calculate the energy absorbed into the cup and add it to the energy calculated in the solutions reaction, while the energy or heat absorbed in the glass will already escaping and so it will be a lesser value(calorimeter constant) that is added to the energy in the solutions reaction..... This was hard to grasp since initially i thought the energy being released from the reaction, into the glass would mean it heats up the glass more than the styro cup, and i thought that it would have more energy to be added to the energy calculated in the reaction
Is metal stronger than styrofoam?
Yes, metal is very much stronger than Styrofoam. Note, Styrofoam is a brand trade mark, forextruded polystyrene foam, much used as an insulator and packaging material.
Will a metal cup or a styrofoam cup keep the hot water warm after a short time?
It is the Styrofoam cup as it is not a good conductor of heat but the metal cup is a good conductor of heat.
Why Styrofoam can be a best insulator?
It's not metal or copper like wires. Metal is an easy conductor of heat. Styrofoam isn't. Therefore making it an insulator. Answered by a fifth grade student
What keeps water hotter paper or styrofoam?
styrofoam, but warning fammable and unsafe for the environment!
Is a Styrofoam cup a lightweight substance?
Styrofoam is indeed lightweight compared to other substances from which cups are made such as clay, metal or glass.
Why does the temperature of a metal fall from it maximum value after it transfer from hot to cold water in a Styrofoam cup?
hmmm i need d answer 4 dis 2... let me guss... physics lab question rite?
Why would water in a metal mug cool down so quickly?
Because metal is a good conductor of heat it absorbs heat from material touching its surfaces, and transfer to air.
Which has more mass styrafoam or metal?
mass is sort of like the measure of an objects volume, and has no set number per substance, but density is a fixed figure. As to which object is denser, it depends what type of metal you are talking about, but most of the time metal would be more dense. As to how much mass they have, it depends how big the piece of Styrofoam is, and what type and how big the metal is.
