What is the specific heat value for water?
What is the specific heat value for water?
4,184 Joules
Precisely, water has to absorb 4,184 Joules of heat (1 calorie) for the temperature of one kilogram of water to increase 1°C. For comparison sake, it only takes 385 Joules of heat to raise 1 kilogram of copper 1°C.
What is the specific heat of polyethylene?
Thermal Properties
| Coefficient of thermal expansion ( x10-6 K-1 ) | 100-200 |
|---|---|
| Heat-deflection temperature – 1.8MPa ( C ) | 46 |
| Specific heat ( J K-1 kg-1 ) | 1900 |
| Thermal conductivity @23C ( W m-1 K-1 ) | 0.45-0.52 |
| Upper working temperature ( C ) | 55-120 |
How do you find the specific heat of water vapor?
Calculate specific heat as c = Q / (mΔT) . In our example, it will be equal to c = -63,000 J / (5 kg * -3 K) = 4,200 J/(kg·K) . This is the typical heat capacity of water.
What is the heat capacity of plastic?
| Product | Specific Heat – cp – | |
|---|---|---|

| Plastics, foam | 0.3 | 1.3 |
| Plastics, solid | 0.4 | 1.67 |
| Platinum, 0oC | 0.032 | 0.13 |
How is specific heat used in engineering toolbox?
You can make ads in the Engineering ToolBox more useful to you! Specific heat (C) is the amount of heat required to change the temperature of a mass unit of a substance by one degree.
