\( \Delta Q = m c \) \( \Delta T \)

\( C = \dfrac{\Delta Q}{m} \)\( \Delta T \)

\(m = \dfrac{\Delta Q}{c}\)\( \Delta T \)

\(T_i = \dfrac{\Delta Q}{m c-T_f}\)

\(T_f = \dfrac{\Delta Q}{mc + T_i}\)

\(t = m c\)\(\dfrac {\Delta T }{\Delta Q}\)

The online calorimetry calculator estimates the heat and energy that is released or absorbed by the chemical reaction. You can overcome complex calorimetry problems with the help of a calorimeter constant calculator. 

What Is Calorimetry?

“Calorimetry is the term used to measure the amount of heat that is transformed to and from the substance”. 

Calorimetry calculations are based on the law of conservation of energy. There are two conditions to evaluate the heat energy by this term that are as follows:

  • If heat is released from the chemical reaction then the heat capacity of calorimeter calculator shows that the reaction is exothermic
  • If the heat is absorbed by the chemical reaction then the calorimetry equation calculator displays that the reaction is endothermic. 

Calorimetry Formula:

With the help of the Calorimetry calculator, you can determine whether the reaction is exothermic or endothermic.

$$ \text{Total heat energy} = Q = \Delta{Q_{1}} + \Delta{Q_{2}} + \Delta{Q_{3}}+ … + \Delta {Q_ {I}} $$

$$ \text{Total heat energy} = Q = {m_{1}} × c_{1} × \left(T_{final} – T_{initial}\right) + m_{2} × c_{2} × \left(T_{final} – T_{initial}) (2)\right) +… + m_{i} × c_{i} × \left(T_{final} – T_{initial}\right) $$

$$ \Delta Q = m c \Delta T $$ 


  • ΔQ is the change in heat and energy = Q2 - Q1
  • m is the mass of the given body
  • c is the heat capacity of an object
  • ΔT is the rate of change of temperature = T2 - T1

How To Calculate Heat Capacity of Calorimeter?

Even the calorimetry calculator estimates the enthalpy change in the chemical reaction in a coffee cup calorimetry. A better way to understand calorimetry problems can be demonstrated by an example.


Let us suppose 0.5kg of ice is poured into the 2kg mercury that is in a bucket at 27°C on the other side the mercury has a temperature of 100°C and the temperature of ice is -25°C. The specific heat capacity of the ice is 1.999 (J/g.k) and mercury is 4.2 (J/g.k). You need to evaluate the final temperature that is at the end of the reaction. 


Given Data: 

  • Mass of Ice = 0.5kg or 500g
  • Mass of Mercury = 2kg or 2000g
  • Initial temperature of Ice Ti2 = -25°C  + 273°C  = 248k
  • Initial temperature of Mercury Ti1 = 27°C + 273°C = 300k
  • Final Temperature of Mercury Tf2 = 100°C
  • Final temperature of Ice Tf1 =?

As we know the calorimetry equation that is as follows:

$$ T_{f1} = \dfrac{-m_2c_2(T_{f2} - T_{i2})+T_{i1}}{m_1c_1} $$

$$ T_{f1} = \dfrac{(-2000000)(4.2)(100-300)+(248)}{(500)(1.999)} $$

$$ T_{f1} = \dfrac{(-8400000)(-200)+(248)}{(999.5)} $$

$$ T_{f1} = \dfrac{(--1680000000)+(248)}{(999.5)} $$

$$ T_{f1} = \dfrac{(--1679999752)}{(999.5)} $$

$$ T_{f1} = -1680840.172 $$

Working of Calorimetry Calculator:

To understand the working of a coffee cup calorimeter calculator it is important to take into account the following points. 


  • Choose the type of the reaction
  • Set the factor that you want to calculate
  • Put the mass with their appropriate unit 
  • Enter the value of specific heat capacity by setting their unit 
  • Place the change in temperature ΔT
  • Tap “Calculate”


Below are the results you will receive when using our calorimetry calculator.

  • Specific heat capacity from the chemical reaction
  • The change in the temperature, energies, and masses of bodies 
  • Step-by-step calculations 

Concept of Enthalpy In Calorimetry Calculations:

A thermodynamic quantity that is equal to the total heat content of a system. It is equal to the internal energy of a system and the product of pressure and volume. It realizes  how much heat is available in the system  


Example: If water freezes into the ice some amount of energy is lost during this task. This is called enthalpy. 

According to the law of conservation of energy, the enthalpy change is equal to the transfer to the system.   


What Is The Heat Capacity of an Object?

Heat capacity is the physical property of the matter and is defined as:

“The amount of heat that is required to raise the temperature of 1°C or 1 kelvin”. Joule per kelvin per kg (J/g.K) is the unit that is used to indicate the heat capacity of a body. 

Where Is Calorimetry Used In Industry?

In the pharmaceutical industry, calorimetry is used to design drugs and measure heat change. These are used to control the quality control and for the examination of metabolic rate. 

What Does Calorimetry Depend On?

The calorimetry depends on the conservation of the energy that tells us the energy neither be created nor destroyed but changes from one state to another 

Why Is Water Used In The Calorimetry?

Water is an excellent heat absorber and it has the highest specific heat. It means that it takes into account the maximum energy to enhance the temperature of water compared to other substances.
