Calorie calculation is very important to determine and recognize calorie intake, so we must remember that it is about calorie count to know your energy level.

When we want to count calories, we must perform a mathematical operation with which we can get the expected result and which will show us how many calories we can have and which of them go into the heat capacity.

## Formula To calculate heat capacity:

The formula we will use is as below:

**heat capacity = (heat energy) / (temperature rise)**

## How is the heat capacity of an object calculated?

When we want to calculate the heat capacity of an object, we must take a number of considerations into account. Here we detail the steps that need to be followed; We are talking about a formula, which in this case will look like:

**heat capacity = E/T**, as we described in the previous paragraph.

Therefore, where we write the amount of thermal energy, we write the cause of this energy. When increasing the temperature, we will provide the specified temperature as long as it appears, we can still record the value that appears in the problem. And we are not talking about thermal energy.

## The specific heat of a material

When we talk about specific heat capacity, we are talking about the energy required to increase one gram by one degree so that we can work the formula correctly.

Once we find the heat capacity of a unit, which can range from a gram to an ounce to a kilogram, we can determine the specific heat capacity of that object. So we have that specific heat refers to the amount of energy required to increase by one unit of degree.

That is, if a gram of the Sun takes 0.418 days to rise by 1 degree Celsius, we find that the specific heat of the Sun is 418 J/°C x g.

## What is the specific heat of common materials?

Specific thermal values of common materials. They can be found in everyday life. That’s why if you practice or measure the heat capacity of common things and elements, you can quickly find out what that specific heating value will be:

- In the case of water we find that it has a specific value of 40179 J/°C.
- Air has a specific heat of combustion of 1.01 J/°C.
- Wood: 1.79
- Aluminum has the following value: 0.902 J/°C.
- Gold costs 0.129 J/°C.
- And iron 0.450

### How to calculate heat capacitor of water?

To calculate the heat capacity of water, you can use the following formula:

**Q = m * C * ΔT**

Here:

**Q**is the heat energy in joules (J) or calories (cal).**m**is the mass of the water in grams (g).**C**is the specific heat capacity of water (4.184 J/g°C or 1 cal/g°C).**ΔT**is the change in temperature in degrees Celsius (°C) or Kelvin (K).

### How to calculate heat capacitor of metal?

Use the formula (Q = m * C * ΔT) to calculate the heat capacity (Q) of the metal.

### Example of how to calculate heat capacity of calorimeter with water?

Suppose you have 200 grams of water (m_water = 200 g) in a calorimeter, and you burn a substance inside the calorimeter that releases 5000 J of heat. The initial temperature of the water is 25°C, and the final temperature after the reaction is 45°C.

ΔT = T_final – T_initial = 45°C – 25°C = 20°C

Q_water = 200 g * 20°C * 4.184 J/g°C = 16.736 J

C_calorimeter = -16.736 J / 20°C = -837 J/°C

Therefore, the heat capacity of the calorimeter is approximately 837 J/°C, which includes both the heat capacity of water and the heat capacity of the calorimeter itself.
