Into a 0.500-kg aluminum container at 20.0C is placed 6.00 kg of ethyl alcohol at 30.0C and 1.00 kg ice at 210.0C. Assume the system is insulated from its environment. (a) Identify all five thermal energy transfers that occur as the system goes to a final equilibrium temperature T. Use the form substance at XC to substance at YC. (b) Construct a table similar to the table in Example 11.5. (c) Sum all terms in the right-most column of the table and set the sum equal to zero. (d) Substitute information from the table into the equation found in part (c) and solve for the final equilibrium temperature, T.
Thomas 1 Trigonometry Example: Pythagorean Theorem: Scalars & Vectors Scalar quantities are just a number 1. Examples: a. Temperature b. Height c. Mass 2. Note that scaler quantities exclude physical quantities Vector Quantities 1. Vectors are described by magnitude and direction arrows. a. The arrows indicate the direction of the vector. b. Vectors can be used to describe forces, acceleration, and velocity. c. R vectors is proportional to the magnitude of the vector. Vector Addition 1. Consider magnitude and direction while using these. 2. All vectors as seen on a diagram should
