The Car Heat Calculator helps you determine the amount of heat energy absorbed or released by a car when its temperature changes.
Enter the car’s mass, the temperature change, and its specific heat capacity, you can calculate the heat energy required for the temperature change.
Car Heat Energy Calculator
How to Use:
 Enter Mass of the Car (kg): The weight of the car in kilograms.
 Enter Temperature Change (°C): The difference between the car’s initial and final temperatures.
 Enter Specific Heat Capacity (J/kg/°C): This value, unique to each material, shows how much energy is needed to raise 1 kg of material by 1°C.
 Heat Energy (J): The calculator will display the heat energy needed, in joules.
Example Calculations
Example 1:
Step 
Input 
Calculation 
Result 
Mass of Car 
1200 kg 


Temperature Change 
30°C 


Heat Capacity 
900 J/kg/°C 


Heat Energy 

$1200 \times 30 \times 900 = 32,400,000$ J 
32,400,000 J 
In this example, a car weighing 1200 kg with a temperature change of 30°C and a heat capacity of 900 J/kg/°C requires 32,400,000 J of heat energy.
Example 2:
Step 
Input 
Calculation 
Result 
Mass of Car 
1500 kg 


Temperature Change 
20°C 


Heat Capacity 
1000 J/kg/°C 


Heat Energy 

$1500 \times 20 \times 1000 = 30,000,000$ J 
30,000,000 J 
For a car weighing 1500 kg and a temperature increase of 20°C, with a heat capacity of 1000 J/kg/°C, the heat energy needed is 30,000,000 J.
