D59You can use the empty mass of the cup and the mass of the cylinder from trial 1 but you mustdetermine the new mass of water used in trial 211. For EACH of your trials, calculate the specific heat of the metal in cal/g C (seeIntroduction). Assume that the mitial temperature of the metal was the temperature of theboiling water Use a specific heat for water of 1.00 calg C. Average the results from eachof the trials to obtam the experimentally determined specific heat of your metal12. Dry your metal cylinder AND RETURN IT TO YOUR INSTRUCTOR.

Heat transfer, Conservation of Energy question: Students A and B used the following steps to find the heat capacity of a sample of duraluminalloy:1. Filled a polystyrene cup with approx. 125 g of water at temp 55°C2. Observed the temperature of the hot water at 1 minute intervals for 8 minutes3. Took duralumin metal sample from constant temperature vessel at approx. 20°C and submergedit in the hot water4. Observed the temperature of the water plus duralumin at 1 minute intervals for 8 more minutes See the image below for the results. 1. in what ways was heat energy transferred in this experiment? Is it the hot water transfer heat to the alloy sample and the environment of something else? 2. Should the data point at t=+0.5 minutes be included in the line of best fit for positive time? 3. What were the temperature changes of the water and the alloy sample, estimate the uncertainties? 4. Find the specfic heat capacity of the duralumin alloy sample. Estimate the uncertainty in this…
Please don't copy and written by hand As shown in the figure below, you have a system including a Cadmium vessel with mass Mvessel = 0.477 kg. The vessel contains water with mass Mwater = 0.219 kg. Both the vessel and water are initially at a temperature of 45.0 degrees Celsius. You add steam into the system. The steam has an initial temperature of 157.9 degrees Celsius and a mass of Msteam = 6.9289 kg. The system will reach equilibrium with all the water having vaporized at some final temperature above 100 degrees Celsius.Find the system final temperature, Tfinal = degrees Celsius Material c (J/(kg K)) Aluminum 897 Beryllium 1820 Cadmium 231 Iron 412 Lead 129 Polyethylene 2303 Steel 466 Uranium 116 Water c (J/(kg K)) ice 2090 water 4186 steam 2010

Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. A 0.051-m³ rigid tank initially contains refrigerant-134a at 0.8 MPa and 100 percent quality. The tank is connected by a valve to a supply line that carries refrigerant-134a at 1.2 MPa and 40°C. Now the valve is opened, and the refrigerant is allowed to enter the tank. The valve is closed when it is observed that the tank contains saturated liquid at 1.2 MPa. The properties of refrigerant are ₁ = 0.02565 m³/kg, u₁ = 246.82 kJ/kg, 2 = 0.0008935 m³/kg, u2 = 116.72 kJ/kg, and h;= 108.28 kJ/kg. Determine the mass of the refrigerant that has entered the tank. (You must provide an answer before moving on to the next part.) The mass of the refrigerant is kg.
