What are the differences between simple calorimeter and bomb calorimeter?
bomb calorimeter measures heat transfer at constant while the cup measures at constant pressure.
What are the different types of calorimeters?
Bomb calorimeter and coffee-cup calorimeter. Both useful, however, the bomb calorimeter is better to use if you're measuring deltaH of a gas
What measures the heat of the chemical reactions?
A calorimeter is a device used to measure the quantity of heat flow in a chemical reaction. Two of the most common types of calorimeters are the coffee cup calorimeter and the bomb calorimeter..........For more info., referSpecial:UnAnsweredQ
What is the mass of a cup of coffee?
The volume is 6 fluid ounces
What kind of cup would you use to make a calorimeter?
Styrofoam Cup
What is the best way to measure calorimetry?
Calorimetry is the scientific practice of measuring the heat that a reaction between energies may create, and there are two different types of measurements one can take; they are based on constant pressure and constant volume. To measure calorimetry, one should employ the use of a calorimeter (which is basically an insulated object like a styrofoam cup). One must then seal the reactants in the calorimeter and measure the change change in temperature, comparing the previous temperature to the temperature after the experiment.
How do you use a calorimeter?
A calorimeter is used to keep heat contained in a single place as the calorimeter absorbs very little heat and the amount it absorbs can easily be calculated. To use the calorimeter heat the liquid you want (or cool) and place it in the calorimeter cup and put that in the calorimeter and place the lid on top and the thermometer in the thermometer's hole. There you go. Simple as that. A calorimeter is used to keep heat contained in a single place as the calorimeter absorbs very little heat and the amount it absorbs can easily be calculated.

Which conditions exists in a cup calorimeter?
Normal atmospheric pressure
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
What is the best mesusurement for the capacty of a coffee cup in ml?
A best measurement doesn't exist.The volume of a coffee cup is very variable ariund the world: from 30 mL to 200 Ml.
When 1.0 mol 58.44 g of sodium chloride is dissolved in 100.0 g of water in a coffee-cup calorimeter the temperature of the water drops from 20.0C to 14.1C What is the heat of solution for sodi?
3900
How is heat measured in a calorimeter?
An insulated container with a thermometer to measure change of heat can be used as a calorimeter. Example a polystyrene cup with a lid.
