The Energy Gained by Water Calculator helps you find out how much energy water absorbs when it gets heated. This tool is useful in science labs, engineering settings, classrooms, and even daily life. It allows users to calculate energy transfer based on mass, 比热和温度变化。
The calculator belongs to the Thermal Energy and 热量 转让 category. It’s especially valuable for evaluating thermal systems, conducting experiments, and improving heating processes.
Formula of Energy Gained By Water Calculator
Energy Gained by Water Formula:
Q = m × c × ΔT
详细分类：
- Q = Energy gained by water (in joules)
- m = Mass of water (in kilograms)
- c = Specific heat capacity of water = 4186 J / kg·°C
- ΔT = Change in temperature = Final temperature − Initial temperature (in °C)
This formula calculates how much heat water absorbs when its temperature increases. The constant 4186 reflects how much energy is needed to raise 1 kg of water by 1°C.
Reference Table: Quick Lookup for Common Scenarios
| 质量（公斤） | ΔT (°C) | Energy Gained (kJ) |
|---|---|---|
| 1 | 10 | 41.86 |
| 2 | 15 | 125.58 |
| 0.5 | 20 | 41.86 |
| 3 | 5 | 62.79 |
This table provides quick results for frequently used combinations, so users can save 次 without doing manual calculations.
Example of Energy Gained By Water Calculator
Let’s say you heat 2公斤 来自的水 25°C至75℃，.
- ΔT = 75 − 25 = 50℃，
- 使用公式：
Q = 2 × 4186 × 50
问 = 418600焦耳 or 418.6千焦
The water gains 418.6千焦耳 的能量。
最常见的常见问题解答
这是 4186 J / kg·°C, which means water requires 4186 joules to raise 1 kg by 1°C.
No. This calculator is made for water. Other substances have different specific heat values.
It helps understand how much heat energy is involved in heating water for labs, cooking, or industrial use.
