What are the differences between simple calorimeter and bomb calorimeter?
bomb calorimeter measures heat transfer at constant while the cup measures at constant pressure.
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 is principle of working of bomb calorimeter?
A bomb calorimeter is a type of constant-volume calorimeter used in measuring the heat of combustion of a particular reaction. Bomb calorimeters have to withstand the large pressure within the calorimeter as the reaction is being measured. Electrical energy is used to ignite the fuel; as the fuel is burning, it will heat up the surrounding air, which expands and escapes through a tube that leads the air out of the calorimeter. When the air is escaping through the copper tube it will also heat up the water outside the tube. The temperature of the water allows for calculating calorie content of the fuel
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

What instrument measures the heat released at constant volume?
a calorimeter

The q calorimeter is the constant and will be needed to find the q metal.
What is the unit of stefan' constant?
what is the unit of Stefan constant
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 bomb caloriemeter?
Bomb calorimeter is the apparatus used to find the change in internal energy with respect to heat capacity at constant pressure.
Function of calorimeter?
A bomb calorimeter is a type of constant-volume calorimeter used in measuring the heat of combustion of a particular reaction. Bomb calorimeters have to withstand the large pressure within the calorimeter as the reaction is being measured. Electrical energy is used to ignite the fuel; as the fuel is burning, it will heat up the surrounding air, which expands and escapes through a tube that leads the air out of the calorimeter. When the air is escaping through the copper tube it will also heat up the water outside the tube. The temperature of the water allows for calculating the calorie content of the fuel.[ or kilojoules if using those units]

What is the SI unit of force constant?
I am not sure what you mean with "force constant". The SI unit of force is the newton.
Is Calculate the Calorimeter Constant if 25 g of water at 56C was added to 25 g of water at 25C with a resulting temperature of 35C?
205 cal
What is the principle of Bunsen calorimeter?
bomb calorimeter is heat combustion
What are the Advantages of throttling calorimeter?
An instrument utilizing the principle of constant enthalpy expansion for the measurement of the moisture content of steam; steam drawn from a steam pipe through sampling nozzles enters the calorimeter through a throttling orifice and moves into a well-insulated expansion chamber in which its temperature is measured. Also known as steam calorimeter.
