Assessment Ideas Michigan Merit Curriculum requires students to recognize a relationship between the pressure, volume, and temperature of a gas and to create and interpret graphs. One may want to provide sample graph and ask students to match it with selections of data or predict which variable relationship is being represented in the graph. Indicate the relationship between the pairs of gas variables by writing “I” for increase, “D” for decrease, or “NBA” for will not be affected. a. If the temperature decreases, the average kinetic energy of the particles will b. If the number of moles of gas decreases the gas pressure will c. The temperature of the gas increases, the gas pressure will d. If the temperature decreases, the rate of diffusion will e. If the mass of the individual gas particles decreases, the rate of diffusion will In the gas stations, a student made sure the cap was on the syringe, inserted a marshmallow, than tried WITH DIFFICULTY to push the plunger as far into the syringe as you could. Use the symbols “I” for increases “D” for decreases, or “S” for remains the same to explain what was happening to the gas in the syringe. a. The distance between the gas particles b. The size of the marshmallow c. The mass of the gas d. The volume occupied by the gas e. The moles of gas f. The amount of collisions with other gas particles and the walls of the plunger g. The amount of force required by you to “decompress” the air Determine if the relationship is direct (D), inverse (I), or no relationship (NR). a. Volume of a non-stretchy container (like the syringe) and the pressure of the gas within the container b. Volume of a flexible container (like a balloon) and the temperature of the gas within the balloon c. Temperature of a gas and the pressure of the gas 16
The math level can be upgraded by requiring student to calculate values of pressure, volume, temperature, and number of moles using the various gas law equations. Students should be able to determine from the question which equation is appropriate, rearrange the equation to solve for the missing variable, enter the given values in for the appropriate variable, and calculate the missing information.
