**Introduction**

Calculating water cooling time is crucial for various applications, such as industrial processes, scientific experiments, and everyday tasks. To simplify this, we’ve developed an easy-to-use Water Cooling Time Calculator using HTML and JavaScript.

**How to Use**

Using the Water Cooling Time Calculator is straightforward. Enter the initial and final temperatures of the water, the mass of the substance, and the specific heat capacity. Click the “Calculate” button to obtain the accurate cooling time.

**Formula**

The formula for calculating the water cooling time is given by:

$Cooling Time=h⋅Am⋅c⋅(T−T) $

Where:

- $m$ is the mass of the substance.
- $c$ is the specific heat capacity of water.
- $T_{i}$ is the initial temperature.
- $T_{f}$ is the final temperature.
- $h$ is the heat transfer coefficient.
- $A$ is the surface area of the substance.

**Example**

Let’s consider an example:

- $m=500$ g
- $c=4.186$ J/g°C (specific heat capacity of water)
- $T_{i}=70$ °C
- $T_{f}=20$ °C
- $h=0.025$ J/(s·cm²·°C)
- $A=100$ cm²

$Cooling Time=⋅⋅⋅(−) $
