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, specific heat, and temperature change.
The calculator belongs to the Thermal Energy and Heat Transfer 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
Detailed Breakdown:
- 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
| Mass (kg) | 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 time without doing manual calculations.
Example of Energy Gained By Water Calculator
Let’s say you heat 2 kilograms of water from 25°C to 75°C.
- ΔT = 75 − 25 = 50°C
- Use the formula:
Q = 2 × 4186 × 50
Q = 418600 joules or 418.6 kJ
The water gains 418.6 kilojoules of energy.
