Question

A bomb calorimeter is used to measure the value of heat of reaction at a constant
A. Volume.
B. Pressure
C. Temperature
D. None of these

Answer 1

Hint:Calorimeter is an instrument that is used to measure the heat of chemical reactions, heat capacities of substances as well as physical changes of objects. It is highly useful in the fields of thermodynamics.

Complete step by step solution:
A bomb calorimeter is also known as a constant-volume calorimeter used in measuring the heat of combustion of a particular reaction. The bomb calorimeter should withstand a large number of pressures in the calorimeter as the reaction is being measured.
So, a bomb calorimeter is used to measure the value of heat of reaction at a constant volume.

So, the correct answer is A.

Additional information:
Let us understand the structures and functions of some instruments which are used in measuring different parameters.
Pipette: Pipette can be explained as a media dispensing device, that is effective in keeping track of the volumetric transfer of material while in operation. It is usually a glass-based tube-like structure. Pipettes exist in various configurations which vary in the levels of precision and accuracy required. This instrument is used to measure the specific volume of liquid is a pipette.
Manometer: Manometer is an instrument that is used for measuring pressure. it comes in a variety of configurations to satisfy the level of sensitivity of scale required.
Balance: A balance is a measuring device that can be used to measure the weight of a given object. Similar to manometers, it is available in several configurations to satisfy the different sensitivities required.

Note:
The specific volume of a liquid is the physical property which can be understood as the ratio of the volume of the liquid to the total mass of the liquid. To put it in simpler terms, it is the reciprocal of the density of the substance. To be more specific, volumetric pipette’ can be used for measuring the specific volume of a liquid.
