Calculation Example:

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}
