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.
What is the unit for the equilibrium constant?
The unit for the equilibrium constant is dimensionless.
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.
Is a coffee cup calorimeter a constant volume calorimeter?
Yes, a coffee cup calorimeter is considered a constant pressure calorimeter rather than a constant volume calorimeter. It typically consists of two cups, with an insulating layer between them, allowing for reactions or processes to occur at atmospheric pressure while maintaining a relatively constant temperature. The calorimeter measures the heat exchanged during a reaction at constant pressure, which is reflected in the temperature change of the water inside.
What instrument measures the heat released at constant volume?
a calorimeter
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.
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 difference between a bomb calorimeter and a coffee cup calorimeter?
A bomb calorimeter is a sealed device used to measure the heat of combustion of a substance under constant volume, typically in a controlled environment, allowing for high-pressure reactions. In contrast, a coffee cup calorimeter is an open system that measures heat changes in reactions occurring at constant pressure, making it suitable for simpler experiments like neutralization or dissolution in aqueous solutions. The bomb calorimeter is designed for high-energy reactions, while the coffee cup calorimeter is more suited for less intense reactions.
Is volume constant in bomb calorimeter?
In a bomb calorimeter, the volume is not constant; it is typically operated under constant volume conditions. This means that the reaction occurs in a rigid, sealed container where the volume does not change during the combustion process. The constant volume allows for accurate measurement of the heat released during the reaction, which is essential for calculating the calorific value of the substance being tested.

What is the bomb calorimeter formula used to calculate the heat released during a chemical reaction?
The bomb calorimeter formula used to calculate the heat released during a chemical reaction is: q C x T where: q heat released (in joules) C calorimeter constant (in joules per degree Celsius) T change in temperature (in degrees Celsius)
