Extra Credit Option: Reinforcement and Punishment Activity Instructions: Think of real-life examples that demonstrate the following: Positive Reinforcement, Negative Reinforcement, Positive Punishment, Negative Punishment. Below is a template to do your work. Please replace the italicized words with the appropriate terms from your example and fill in the blanks accordingly. Follow the format below to write your sentences. Note: Example sentences are in CAPS. Reinforcer: a stimulus that increases the likelihood of a specific behavior/response to occur (or be repeated). Positive reinforcement: The ______ of a stimulus to increase the probability that a behavior will be repeated EXAMPLE SENTENCE: The addition of a stimulus (Feeding a rat) after it has pressed a lever (increased behavior) Negative reinforcement: The ______ of a stimulus to increase the probability that a behavior will be repeated EXAMPLE SENTENCE: The removal of a stimulus (Getting rid of a headache) by taking a pill (increased behavior) Punishment: Change that happens that decreases the likelihood of a specific behavior/response to occur (or be repeated). P ______ punishment: The addition of a stimulus to ______ the probability that a behavior will be repeated EXAMPLE SENTENCE: The addition of a stimulus (A speeding ticket is given (added)) to decrease the probability of speeding (decreased behavior) Negative ______: The ______ of a stimulus to decrease the probability that a behavior will be repeated EXAMPLE SENTENCE: The removal of a stimulus (Child's loss of privileges such as playing video games (removal)) to decrease the probability of misbehaving (decreased behavior).

A light which is placed on the end of a steel pipe (with a round cross-section) is going to be hung from a ceiling by press-fitting the steel pipe into a flat, washer-shaped piece of metal bolted to the ceiling. This press-fit results in a 50 N normal force between the washer piece and the pipe. The mass of the light and steel pipe is 10 kg. Since this is a press fit, friction will hold the pipe in place. In order to assure that the pipe doesn't move, based on the table below, which metals could you use for the washer-shaped piece? If the washer is made from steel, which polymers could you use for the pipe material (you can assume the same total mass as with the steel pipe)?

Tank A, see image below, has a volume of $V_A = 2.5 \text{ m}^3$ and initially contains air at $T_{A,1} = 15 \text{ }^\circ \text{C}$ at a pressure of $P_{A,1} = 400 \text{ kPa}$. Tank B, which is connected through a valve to tank A, initially contains $m_{B,1} = 5.0 \text{ kg}$ of air at $T_{B,1} = 30 \text{ }^\circ \text{C}$ and $P_{B,1} = 700 \text{ kPa}$. $P_{A,1}$ and $P_{B,1}$ are given in absolute pressure. Determine the volume of tank B. $V_B = \text{________} \text{ m}^3$ When the valve is opened and when the entire system is allowed to reach thermal equilibrium with the surroundings at $T_0 = 20 \text{ }^\circ \text{C}$, determine the final equilibrium pressure $P_3$ of the air inside the tanks. Give your answer in absolute pressure. $P_3 = \text{________} \text{ kPa}$ A mass of $m = 0.1 \text{ kg}$ of helium fills a $V = 0.2 \text{ m}^3$ rigid vessel at $P_1 = 350 \text{ kPa}$. The vessel is heated until the pressure $P_2 = 700 \text{ kPa}$. Calculate the change in temperature. Use $R_{He} = 8.314 \text{ J mol}^{-1} \text{K}^{-1}$ and a molar mass $M_{He} = 4 \text{ g mol}^{-1}$. $\Delta T = \text{________} \text{ }^\circ \text{C or K}$
