Test question – Write a test question and Question or application – Ask a question or describe answer. how this applies to real life. 2. Questions by Learning Target: The following questions are divided into sections by Learning Target. You should focus first on the sections that you have identified as your weakest sections according to your Learning Target Log. LT 6.1: I can explain how pressure is created through the collisions of gas molecules with a surface. a) What is pressure? Describe how pressure is created within a container using the terms force, area, and collision. b) Draw a picture of a box that illustrates pressure. Label your picture with force, area, and collision. c) Where is pressure greater, on top of a mountain or at sea level? Explain your answer. d) Where is pressure greater, 100 meters below the ocean or at sea level? Explain your Name: Per: ___ answer. e) Why does pressure increase when you pump up your bike tire? LT6.2: I can discuss how the diffusion of a gas through a space is the result of the random motion of a gas molecule. a) What is diffusion? How does the motion of gas molecules explain how a gas diffuses throughout a room? b) Draw a picture that illustrates diffusion. c) The average gas moves at about 600 m/s. What explains why you do not smell a gas for a few minutes if you are standing on the other side of a room? Name: Per: ___ LT6.3: I can define what STP is. a) What does STP stand for? b) What is the temperature and pressure at STP? LT 6.4: I can discuss how the kinetic energy of gas molecules is related to the temperature of the gas mixture. a) What is kinetic energy? b) What happens to kinetic energy as temperature increases? As it decreases? c) Draw a graph that illustrates the relationship between kinetic energy and temperature. Label your x-axis with temperature and your y-axis with kinetic energy. What type of relationship is this? LT 6.5: I can define what absolute zero is and relate it to the Kelvin temperature scale. a) Is it possible for temperature to go below 0K? Why or why not? b) Describe what the motion of molecules looks like in the gas phase. Describe what the motion of molecules looks like in the solid phase. Describe what the motion of molecules looks like at 0K. LT6.6: I can convert between Celsius and Kelvin temperature Scales. a) Convert the following Kelvin readings to Celsius: i. 452 K = __________ oC ii. 321 K = __________ oC iii. 2 K = ____________ oC b) Convert the following Celsius readings to Kelvin Name: Per: ___ i. 15 oC = ___________ K ii. -200 oC = _________ K iii. 1400 oC = _________ K GOOD LUCK!!!
