WebFeb 13, 2024 · The equation to calculate specific heat is: Q = s × m × Δ T Q represents the amount of heat, s the specific heat ( Joules gram * ° Celsius ), m the mass of the substance in grams, and Δ T the observed change in temperature. Different kinds of water, such as seawater, may have different specific heat. What Is the Specific Heat of Water? WebA 0.003 0-kg lead bullet is traveling at a speed of 240 m/s when it embeds in a block of ice at 0°C. If all the heat generated goes into melting ice, what quantity of ice is melted? (Lf = 80 kcal/kg, the specific heat of lead = 0.03 kcal/kg×°C, and 1 kcal = 4 186 J Click the card to flip 👆 Definition 1 / 76 2.6 x 10^-4 kg Click the card to flip 👆

WebThe heat supplied by the fuel oil can be determined through an enthalpy diagram, or by knowing the specific heat. Assuming a specific heat of 1.8 kJ/kg/K, or 0.43 kcal/kg/K. The heat brought by the fuel is then Cp* (T-Tref) = 0.43* (134-0) = 57.7 kcal/kg 6.3 Heat supplied by the air Qair The air contribution is calculated as : Cpair. WebMass, Force, and Units The constant-pressure specific heat of air at 25°C is 1.005 kJ/kg·°C. Express this value in kJ/kg·K, J/g·°C, kcal/ kg·°C, and Btu/lbm·°F.
