6. A mass of 0.20 kg of metal having a temperature of 100 deg. C is plunged into 0.04kg of water at 20 deg. C The temperature of the water and metal becomes 48 deg.C. The latent heat of ice at 0 eg. C is 335 kJ/kg-K and the specific heat capacity ofwater is 4.19 kJ/kg-K. Assuming no heat loss to the surroundings, determine thespecific heat capacity of the metal in kJ/kg-K

Use the concept of calorimetry which states that heat loss by metal is equal to heat gain by…

NOTE: Complete solution and show the derivation/cancellation of units. A steel flask of 0.04 m capacity is used to store Nitrogen at 120 bar and 20°C. The flask is protected against excessive pressure by a fusible plug which will melt and allow the gas to escape if the temperature is too high. A. How many kilogram of Nitrogen will the flask hold at the design conditions? B. At what temperature in °C must fusible plug melt in order to limit the pressure of flask to a maximum of 150 bar?
Please help me with this question thanks sir appreciate
H2. A combustion facility is presumed to produce 9 Gigawatt-hours per year. Electricity price is 1.55 SEK per kWh. By raising the high temperature in the combustion facility från 373°C to 423°C to raise the efficiency. Calculate the repayment time for an investment of 1,730,000 SEK (operating cost staying the same). Assume that the facility is in a 12°C environment. (Clue: What expressions exist for the maximum thermal efficiency)

please help me with this
The machine is commenced to be heated at some point of a quasi-equilibrium manner till the temperature of air reaches to 900 K. During the manner the stress within the cylinder is held constant. Initially, 1kg air at 600K and at 150 kPa is contained in a piston - cylinder device. Air may be assumed as Ideal Gas below those conditions. a) Calculate the heat supplied to the air within the cylinder at some point of this process. b) Sketch the P[kPa]-V[m³] diagram of the process. Indicate the path of the process. No want to explicit the extent of the air at the diagram. Please do best a difficult sketch. c) Calculate the paintings achieved with the aid of using the air onto surrounding.
