What is the heat generation formula used to calculate the amount of heat produced in a system?
The heat generation formula used to calculate the amount of heat produced in a system is Q mcT, where Q represents the amount of heat produced, m is the mass of the substance, c is the specific heat capacity of the substance, and T is the change in temperature.
What is the heat dissipation equation used to calculate the amount of heat transferred from a system to its surroundings?
The heat dissipation equation used to calculate the amount of heat transferred from a system to its surroundings is Q hAT, where Q represents the amount of heat transferred, h is the heat transfer coefficient, A is the surface area through which heat is transferred, and T is the temperature difference between the system and its surroundings.

A device used to calculate the amount of heat energy stored in foods?
A bomb calorimeter is a device used to measure the amount of heat energy stored in foods. It works by burning a sample of the food in an oxygen-rich environment and measuring the temperature change in the surrounding water bath to calculate the energy content of the food.
Why is a measured amount of water needed to determine the spicific heat of a metal object?
A measured amount of water is used in determining the specific heat of a metal object because water has a well-defined specific heat capacity (1 calorie/gram °C) and is readily available. By measuring the temperature change of a known mass of water when a metal object is immersed in it, and knowing the specific heat of water, we can calculate the specific heat of the metal object.
What is the heat capacity equation and how is it used to calculate the amount of heat required to change the temperature of a substance?
The heat capacity equation is Q mcT, where Q represents the amount of heat energy, m is the mass of the substance, c is the specific heat capacity of the substance, and T is the change in temperature. This equation is used to calculate the amount of heat required to change the temperature of a substance by multiplying the mass, specific heat capacity, and temperature change.
How To calculate Specific Heat of A compound Such as NaOH?
Specific heat is the measure of energy it takes to raise a unit mass in temperature by one degree Celsius. When measuring a compound that is water soluble, heat it separately to a specific range, then use the liquid to calculate the amount of heat that was used.
What is the constant specific heat equation used for in thermodynamics?
The constant specific heat equation is used in thermodynamics to calculate the amount of heat transferred during a process when the specific heat of a substance remains constant.
What is the formula for the change in thermal energy and how is it used to calculate the amount of heat transferred in a system?
The formula for the change in thermal energy is Q mcT, where Q represents the amount of heat transferred, m is the mass of the substance, c is the specific heat capacity of the substance, and T is the change in temperature. This formula is used to calculate the amount of heat transferred in a system by multiplying the mass of the substance by the specific heat capacity and the change in temperature.
What is the heat calculation formula used to determine the amount of heat transferred in a system?
The formula used to calculate the amount of heat transferred in a system is Q mcT, where Q represents the heat transferred, m is the mass of the substance, c is the specific heat capacity of the substance, and T is the change in temperature.

Most specific heat capacities are found by combining a substance with another with a known specific heat usually water. But How do chemists know the specific heat capacity of water in the first place?
The specific heat capacity of water was initially determined through experiments involving measuring the temperature change when a known amount of water absorbs a certain amount of heat. The relationship between the heat absorbed, temperature change, and mass of water was used to calculate the specific heat capacity of water. This value has been confirmed and refined over time through numerous experiments and calculations.
