Feb 15, 2022 · This specific heat calculator is a tool that determines the heat capacity of a heated or a cooled sample. Specific heat is the amount of thermal energy you need to supply to a sample weighing 1 kg to increase its temperature by 1 K.Read on to learn how to apply the heat capacity formula correctly to obtain a valid result.
Heat Required = 5810 lbs x 65 ºF Heat Required = 377,650 BTU/week. 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 ...
Jan 27, 2017 · This will require 266.9 kJ of heat energy. To calculate the energy required to raise the temperature of any given substance, here's what you require: The mass of the material, m The temperature change that occurs, DeltaT The specific heat capacity of the material, c …
Calculate the amount of heat necessary to raise the temperature of 135.0 g of water from 50.4 ° F to 85.0 ° F . The specific heat of water = 4.184 J/g·°C. The specific heat of water = 4.184 J/g·°C.
It is estimated by the United States Department of Energy that a family of four each showering for 10 minutes a day consumes about 700 gal of hot water a week. Water for the showers comes into the home at 55ºF and needs to be heated to 120ºF.
Thus, if you only know the number of gallons, you must convert it into pounds. One gallon of water = about 8.3 pounds, so multiply number of gallons by 8.3 to determine the weight in pounds.
At high temperatures the nitrogen molecule behaves like a one-dimensional harmonic oscillator. In this situation, estimate how much heat must be added to the system in order to increase the temperature of 1 mole of nitrogen gas by 10 degrees Celsius (for constant volume and constant pressure respectively).
A one-dimensional harmonic oscillator has two degrees of freedom, therefore according to the equipartition theorem the average energy of a nitrogen molecule must be . One mole of nitrogen has molecules and so the total internal energy of the gas is .
First of all, a nitrogen molecule is not a one dimensional harmonic oscillator. You are missing a lot of degrees of freedom by this assumption.
