2. An 88.5 gram piece of iron initially at 78.8°C is place in a beaker containing 244 grams of water at 18.8°C. When thermal equilibrium is reached, what is the final temperature? The specific heat capacity for iron is 0.449 J/(g.°C). Assume no heat loss to the surroundings. Assume no heat lost to the surroundings: Heat released by the metal = Heat absorbed by water %3D -qmetal = qwater > qmetal + qwater = 0 %3D mmetalCmetalATmetal + mwaterCwaterATwater = TF = 21.0 °C

Step 2: Identify the dimensions of the quantities involved The second step is to identify the dimensions of the quantities involved in the problem. For example, if the problem involves distance, time, and velocity, the dimensions of these quantities would be length, time, and length/time, respectively. Step 3: Check if the units cancel out The third step is to check if the units cancel out. To do this, multiply the quantities together and check if the units cancel out, leaving only the desired unit. For example, if you are trying to find the velocity of an object and you know its distance and time, you can multiply distance by time to get velocity. If the units cancel out, you have a physically meaningful result. Step 4: Check if the result makes sense, to do this compare the units of the result with what you would expect based on the Robles statement. Using the step hints above, answer the question. You do not have to solve. Just imagine that you're teaching a friend how…
If given a value that is plot along x-axis: 1. Find given value along x axis. 2. From this point, trace a straight line vertically (parallel to the y-axis) until it intersects with the line graph. 3. Then, trace a line horizontally (parallel to the x axis) from the intersect to the y-axis. 4. The value of y corresponding to the given x value is where the traced line intercepts with the y- axis. Based upon what you see in the graph listed below, estimate the cost of the fence installation. 450 350 A 300 4 250 200 150 100 50 10 151 20 25 30 35 Cost (in $)
