What are the differences between simple calorimeter and bomb calorimeter?
A simple calorimeter measures heat changes in a substance through temperature changes in water surrounding it, while a bomb calorimeter measures the heat of combustion of a substance by igniting it in a sealed chamber under high pressure. Bomb calorimeters are more precise and accurate than simple calorimeters, but they are also more complex and expensive to operate.
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.
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 calorimeter is kept in wooden box?
A calorimeter is often kept in a wooden box to provide thermal insulation. Wood is a poor conductor of heat, which helps to minimize heat transfer between the calorimeter and its surroundings, enabling more accurate measurements of heat flow during experiments. This insulation helps to maintain a constant temperature inside the calorimeter, which is essential for reliable results.
Why do you use aluminium foils in calorimeter?
Aluminum foil is used in a calorimeter to cover the sample being tested to prevent heat loss during the experiment. This helps to maintain a constant temperature within the system, ensuring accurate results are obtained.
What instrument measures the heat released at constant volume?
a calorimeter

Difference between isothermal and isoperibol calorimeter?
In an isothermal calorimeter, the temperature inside the calorimeter remains constant during the measurement, preventing any heat exchange with the surroundings. In an isoperibol calorimeter, the calorimeter is well-insulated and allows heat exchange with the surroundings, but the heat loss or gain is accurately measured and compensated for.

what is the unit of Stefan constant

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?
To calculate the calorimeter constant, you first need to use the formula for heat transfer: q=mcΔT, where q is the heat transfer, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature. Since the two water samples reached thermal equilibrium, the heat lost by the hot water is equal to the heat gained by the cold water. By rearranging the equation to find the calorimeter constant, you can solve for it using the given data.
What is the SI unit of force constant?
The SI unit of force constant is newton per meter (N/m).
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.
What is a constant unit?
It is 1.
What is the unit of coulombs law the constant of proportionality has?
The unit of the constant of proportionality in Coulomb's law is Nm²/C² or Vm.
