Using the values for the heat of fusion, specific heat of water, and/or heat of vaporization, calculate the amount of heat energy in each of the following: a. joules released when $125 \mathrm{g}$ of steam at $100^{\circ} \mathrm{C}$ condenses and cools to liquid at $15.0^{\circ} \mathrm{C}$1. Calculate the energy require (in calories) to heat 10.4 g of mercury from 37.0 oC to 42.0 oC. Specific heat of mercury is 0.14 J/g oC. q = m c ∆t q = 10.4 g • 0.14 J/g oC • 5.00 oC = 7.28 J • 1 cal = 1.74 cal 4.184 J 2. If 50. J of heat are applied to 10. g of iron, by how much will the temperature of the iron increase?Dec 14, 2020 · The specific heat capacity indicates how much heat is required to increase the temperature a substance of mass 1 kg by 1 K (1 °C). The greater the specific heat capacity c of a substance, the more heat Q is required to cause a certain temperature change ΔT (assuming the same mass m: (1) Q = c ⋅ m ⋅ Δ T [ c] = kJ kg ⋅ K. 7. How many joules of heat are needed to change 50.0 grams of ice at -15.0 C to steam at 120.0 C? (Cp of H2O = 4.184 J/g C) 8. Calculate the number of joules given off when 32.0 grams of steam cools from 110.0 C to ice at -40.0 C. (Cp of H2O = 4.184 J/g C) 9. The specific heat of ethanol is 2.46 J/g oC.

To do this steam at 150 ∘ C is passed from a boiler into a copper coil immersed in water. The steam condenses in the coil and is returned to the boiler as water at 90 ∘ C. then ___ k g of steam is required per hour. (Specific heat of steam = 1 calorie per gm°C, Latent heat of vaporization = 540 cal/gm) Calculate the heat required to convert 3 kg of ice at -12^(@)C kept in a calorimeter to steam at 100^(@)C at atmospheric pressure. Given, <br> specific heat capacity of ice = 2100 J kg^(-1) K^(-1) <br> specific heat capicity of water = 4186 J kg^(-1)K^(-1) <br> Latent heat of fusion of ice = 3.35 xx 10^(5) J kg^(-1) <br> and latent heat of steam = 2.256 xx 10^(6) J kg^(-1) .The literature value for the specific heat of vaporization of water is therefore somewhat lower with 2257 kJ/kg. Figure: Influence of heat losses on the determination of the specific latent heat of vaporization. Specific heat of vaporization is the heat of vaporization to be added per unit mass of a liquid to be vaporized! ConclusionA: I first take care to look up the specific heat of water in its three phases. Here is the result: "The specific heat capacity, or the amount of heat needed to raise the temperature of a specific substance in a specific form one degree Celsius, for water is 4.187 kJ/kgK, for ice 2.108 kJ/kgK, and for water vapor (steam) 1.996 kJ/kgK."
