Apr 10, 2013 · Using the formula qunknown metal = m × c × T, calculate the specific heat of the metal. Use the data from your experiment for the unknown metal in your calculation. Show ALL your work. qmetal = -205 J = 15.363 g X c X (27.2 - 100.3 C) c = 0.183 J/gC Please hep me, im so lost :(
ChemTeam:How to Determine Specific Heat:Problem 1 - 10The definitions for heat capacity and specific heat capacity may be found here. 1) Solution to (a):q = (50.0 g) (3.1 °C) (4.181 J g¯ 1 °C¯ 1) = 648.52 J. I used 50.0 g because the density of water is 1.00 g/mL and I had 50.0 mL of water. 2) Solution to (b):q = 648.52 J. We assume all heat absorbed by the water was lost by the metal.
8.2.3 Use specific heat values of different substances to determine which would store the most/least amount of thermal energy (heat). 8.2.4 Use specific heat values to calculate thermal energy change, initial, final, or change in temperature as well as mass of material.
Energy Required for Water Heating EGEE 102:Energy The heat requirement for one year is :377,650 BTU/Week x 52 Weeks/Year = 19,637,800 BTU/year or 5,755 kWh. Assuming that the natural gas costs $ 10/MMBTU (1 MMBTU = 1000000 BTU) and electricity costs 0.092 per kWh, the gas costs would be $ 196.37 while electric costs would be $ 529.46. Clearly, electric heat is more expensive than natural gas.

The final steady temperature recorded is 25°C. Calculate the specific heat capacity of the solid. [Specific heat capacity of water = 4200 J kg-1
materials. Specific Heat Capacity of Metals Table Chart. Engineering Materials. Specific Heat Capacity of Metals Table Chart . The specific heat is the amount of heat energy per unit mass required to raise the temperature by one degree Celsius.The relationship between heat and temperature change is usually eed in the form shown below where c is the specific heat .
Temperature Change and Heat Capacity PhysicsHeat Transfer and Temperature Change. The quantitative relationship between heat transfer and temperature change contains all three factors:Q = mcT, where Q is the symbol for heat transfer, m is the mass of the substance, and T is the change in temperature. The symbol c stands for specific heat and depends on the material and phase. The specific heat is the amount of heat necessary to
The final temp after warm metal is put into colder waterThe water specific heat will remain at 4.184, but the value for the metal will be different. These values are tabulated and lists of selected values are in most textbooks. Example #1:Determine the final temperature when a 25.0 g piece of iron at 85.0 °C is placed into 75.0 grams of water at 20.0 °C.
The thermal efficiency, amount of heat added, and the maximum gas pressure and temperature are to be determined. Assumptions 1 The air-standard assumptions are applicable. 2 Kinetic and potential energy changes are negligible. 3 Air is an ideal gas with constant specific heats.
