Heat Gained Formula:
| From: | To: |
Heat gained refers to the thermal energy absorbed by a substance when its temperature increases. It represents the amount of energy transferred to the substance, causing its particles to move faster and increasing its internal energy.
The calculator uses the fundamental heat transfer formula:
Where:
Explanation: The formula calculates the thermal energy required to raise the temperature of a given mass of substance by a specific temperature change, considering the substance's ability to store heat.
Details: Calculating heat gained is essential in thermodynamics, engineering design, climate control systems, cooking, material science, and understanding energy transfer in various physical and chemical processes.
Tips: Enter mass in kilograms, specific heat capacity in J/kg°C, and temperature change in °C. Ensure all values are positive and physically realistic for accurate results.
Q1: What is specific heat capacity?
A: Specific heat capacity is the amount of heat energy required to raise the temperature of 1 kilogram of a substance by 1°C. Different materials have different specific heat capacities.
Q2: Can heat gained be negative?
A: No, heat gained is always positive as it represents energy absorption. If a substance loses heat, it's called heat lost and would be calculated with a negative temperature change.
Q3: What are typical specific heat values?
A: Water: 4186 J/kg°C, Aluminum: 900 J/kg°C, Iron: 450 J/kg°C, Copper: 385 J/kg°C. These values vary with temperature and purity.
Q4: How does this relate to heat lost?
A: Heat gained by one substance equals heat lost by another in a closed system (conservation of energy). The calculations are similar but with opposite signs for temperature change.
Q5: What units should I use?
A: Use consistent SI units: mass in kg, specific heat in J/kg°C, temperature in °C (or K, since the scale difference cancels in ΔT), and heat in Joules.
