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
Can Energy be measured directly with a calorimeter?
Yes energy can be measured directly with a calorimeter. The calorimeter will measure the temperature as it changes in a reaction.
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
In calculating the heat given off by a reaction in a calorimeter you must account for heat absorbed by?
Water and the Calorimeter.
What kind of cup would you use to make a calorimeter?
Styrofoam Cup

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.

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.
What kind of cups would you use to make calorimeter?
Styrofoam Cup
How do you know that a sealed calorimeter is a closed system?
There is an exothermic reaction that occurs when a closed system exists when using a sealed calorimeter. This exothermic reaction can be identified when energy is being released into the environment.
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
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
Will the recorded temperature change for an exothermic reaction performed in a glass calorimeter be greater or less that?
The recorded temperature change for an exothermic reaction performed in a glass calorimeter is less than the Styrofoam cup calorimeter. This is because the glass will conduct heat away more than the Styrofoam.
Difference between isothermal and isoperibol calorimeter?
An isothermal calorimeter is a tool used to bind small molecules to larger macromolecules, and determine the thermodynamic parameters of interactions in a solution. An isoperibol calorimeter measures the heat created by a sample burned under an oxygen atmosphere in a closed vessel surrounded by water, in controlled conditions. The measurement is known as a BTU value.
What is the principle of Bunsen calorimeter?
bomb calorimeter is heat combustion
