Activities

Small Group Activity

30 min.

##### A glass of water
Students generate a list of properties a glass of water might have. The class then discusses and categorizes those properties.
• Found in: Energy and Entropy course(s)

Experiment

60 min.

##### Microwave oven Ice Calorimetry Lab
In this remote-friendly activity, students use a microwave oven (and optionally a thermometer) to measure the latent heat of melting for water (and optionally the heat capacity). From these they compute changes in entropy. See also Ice Calorimetry Lab.
• Found in: Energy and Entropy course(s) Found in: Ice Calorimetry Sequence sequence(s)

Small Group Activity

60 min.

##### Ice Calorimetry Lab
The students will set up a Styrofoam cup with heating element and a thermometer in it. They will measure the temperature as a function of time, and thus the energy transferred from the power supply, from which they compute changes in entropy.

##### Heat and Temperature of Water Vapor
In this introduction to heat capacity, students determine a derivative that indicates how much the internal energy changes as the temperature changes when volume is held constant.

Problem

##### Calculation of $\frac{dT}{dp}$ for water
Calculate based on the Clausius-Clapeyron equation the value of $\frac{dT}{dp}$ near $p=1\text{atm}$ for the liquid-vapor equilibrium of water. The heat of vaporization at $100^\circ\text{C}$ is $2260\text{ J g}^{-1}$. Express the result in kelvin/atm.

Small Group Activity

##### Changes in Internal Energy
Students consider the change in internal energy during three different processes involving a container of water vapor on a stove. Using the 1st Law of Thermodynamics, students reason about how the internal energy would change and then compare this prediction with data from NIST presented as a contour plot.
