Calorimetry Calculator

Do you want to measure the amount of heat energy transferred in a process? Enter the initial temperature, final temperature, mass, and specific heat capacity into the calorimetry calculator then the calculator will then display the heat energy transferred.

Calorimetry Calculator

This calorimetry calculator helps you determine the amount of heat energy (Q) absorbed or released during a temperature change. Input the initial and final temperatures, the mass of the substance, and its specific heat capacity to calculate the heat energy.

Enter the starting temperature of the substance, measured in degrees Celsius (°C).

Enter the final temperature of the substance after the heating or cooling process, measured in degrees Celsius (°C).

Enter the mass of the substance in grams (g). This value is used to calculate how much heat the substance absorbs or releases.

Enter the specific heat capacity of the substance in joules per gram per degree Celsius (J/g°C). This is the amount of heat required to raise the temperature of 1 gram of the substance by 1°C.

What is Calorimetry?

Calorimetry is a science that measures the heat from chemical reactions or physical changes. It involves measuring the temperature change of a substance to find out the heat energy involved. This technique is important in many scientific and industrial applications to understand heat transfer and energy changes.

Examples

1. Basic Example:

Input Field Value
Initial Temperature 25°C
Final Temperature 75°C
Mass 100g
Specific Heat 4.18 J/g°C

Calculation Process:

A. Calculate the Temperature Change (ΔT):

ΔT=Final TemperatureInitial Temperature\Delta T = \text{Final Temperature} - \text{Initial Temperature}
ΔT=75°C25°C=50°C\Delta T = 75°C - 25°C = 50°C

B. Calculate the Heat Energy (Q):

Q=m×c×ΔTQ = m \times c \times \Delta T
Q=100g×4.18J/g°C×50°CQ = 100g \times 4.18 \, \text{J/g°C} \times 50°C
Q=20900JQ = 20900 \, \text{J}

2. Advanced Example:

Input Field Value
Initial Temperature 30°C
Final Temperature 80°C
Mass 150g
Specific Heat 3.85 J/g°C

Calculation Process:

1. Calculate the Temperature Change (ΔT):

ΔT=Final TemperatureInitial Temperature\Delta T = \text{Final Temperature} - \text{Initial Temperature}
ΔT=80°C30°C=50°C\Delta T = 80°C - 30°C = 50°C

2. Calculate the Heat Energy (Q):

Q=m×c×ΔTQ = m \times c \times \Delta T
Q=150g×3.85J/g°C×50°CQ = 150g \times 3.85 \, \text{J/g°C} \times 50°C
Q=28875JQ = 28875 \, \text{J}
