WebbHeat capacity is the amount of heat required to change the temperature of a given amount of matter by 1°C. The heat capacity of 1 gram of a substance is called its specific heat capacity (or specific heat), while the heat capacity of 1 mole of a substance is called its molar heat capacity. WebbSo if you want to know how long it will take for a water heater to come up to temp after being drained, you could use this generic number or calculate it out. BTU (if watts – Watts x 3.413) times recovery efficiency (see AHRI screen shot below) = pounds of water heated 1 degree. Take this & divide by 8.33 (pounds per gallon of water) & then ...

Use the formula ∆H = m x s x ∆T to solve. Once you have m, the mass of your reactants, s, the specific heat of your product, and ∆T, the temperature change from your reaction, you are prepared to find the enthalpy of reaction. blackrock uk equity hedge fund limited
