Which conditions exists in a cup calorimeter?
In a cup calorimeter, conditions such as constant pressure and adiabatic conditions should be maintained to ensure accurate measurement of heat flow in a reaction. This involves insulation to limit heat exchange with the surroundings and a sealed container to prevent energy loss or gain from the system. Additionally, the components within the cup calorimeter should be stable and inert to avoid interference with the reaction being studied.
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 can one build a calorimeter?
To build a calorimeter, one can use materials such as a insulated container, a thermometer, a stirrer, and a known heat source. The calorimeter is used to measure the heat released or absorbed during a chemical reaction. By carefully constructing and calibrating the calorimeter, one can accurately determine the heat changes in a system.
Can Energy be measured directly with a calorimeter?
Yes, energy can be measured directly with a calorimeter by measuring the heat released or absorbed during a chemical reaction or physical process. Calorimeters are designed to isolate the system being studied and measure the heat transfer accurately, allowing for the determination of energy changes.
Is a bomb calorimeter accurate?
Yes, a bomb calorimeter is known for its high accuracy in measuring heat of combustion for various substances. It can provide precise measurements by keeping the system isolated and accounting for all heat transfer mechanisms.
Which explains why a sealed calorimeter is a closed system?

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 is closed system?
1. A closed system is a system which is isolated so that it cannot exchange matter or energy with its surroundings.
What is closed hydraulic system?
It means that the pressurising medium does not leave the system and it is recirculated with make-up or top-up quantity as and when required. This makes it a sealed system to work with.

Should radiator be analyzed as closed system or open system?
A radiator in a car should be analyzed as part of a closed system because it is designed to circulate coolant continuously within a sealed loop without losing or gaining any additional material from the surroundings. This helps maintain an optimal operating temperature for the engine.
What is difference between open system and closed system in thermodynamics?
A system which can exchange mass as well as matter with the surroundings is called anopen system.Example:- Heating of CaCo3 in an open bulb.A system which can exchange energy but not matter is called a closed system.Example:- Calcination of CaCo3 in a sealed bulb.

It means that the pressurising medium does not leave the system and it is recirculated with make-up or top-up quantity as and when required. This makes it a sealed system to work with.
What is a group of objects that only transfer energy to each other?
A closed system is a group of objects that only transfer energy between themselves and do not exchange energy with their surroundings. Examples include a sealed container of gas or a closed-loop mechanical system.
