The Gas Constant R for Ideal Gases
Location: CL2 Mendeleev Lab Instructor: Yunjuan, Zhang Instructions: According to the ideal gas law pV = nRT, if p, V, n, and T are measured in the experiment, the gas constant R can be calculated. In this experiment, a fixed amount of magnesium reacts with excess dilute sulfuric acid to produce hydrogen gas. The gas constant R can be calculated by measuring the volume of hydrogen gas produced. Equipment: None Manual Determination of the Gas...
Determination of the Hardness of Water
Location: CL2 Mendeleev Lab Instructor: Yunjuan, Zhang Instructions: Water hardness is an important monitoring index of water quality. By testing the hardness of the water, we can determine whether the water can be used in industrial production and daily life. The total hardness of water refers to the total amount of Ca2+ and Mg2+ in the water. The higher the content of calcium and magnesium in water, the harder the water. The total hardness of...
The Ratio of Specific Heats of a Gas
Location: PL2 Newton Lab Instructor: Zehao, Pan Instructions: A cylinder is filled with air and a Pressure Sensor is attached. The piston is plucked by hand and allowed to oscillate. The oscillating pressure is recorded as a function of time and the period is determined. The ratio of specific heat capacities is calculated using the period of oscillation, according to Ruchhardt’s method. Equipment: Heat engine/gas law apparatus, large rod stand, 45 cm long steel rod,...
Compound Pendulum
Location: PL2 Newton Lab Instructor: Zehao, Pan Instructions: This experiment explores the dependence of the period of a physical pendulum (a uniform bar) on the distance between the pivot point and the center of mass of the physical pendulum and to find the acceleration of gravity. In addition, the period of oscillation of a physical pendulum will be measured and used to calculate the rotational inertia of the pendulum, which is also determined by measuring...
Air-Track
Location: PL1 Einstein Lab Instructor: Zehao, Pan Instructions: In this experiment, you will understand the physical meaning of resonant and damped motion. In addition, you will master the use of air-track. This experiment explores the spring oscillator model. By measuring the period of vibration of the harmonic oscillator, T, the corresponding fluctuation equation can be derived. Equipment: Air-track, slider, additional weights, springs, photogate, digital millisecond timer.
