Features 23 core lab activities that cover the fundamental concepts of Force & Motion, Energy Transfer, Electricity & Circuits, Fluids and more.

Heat Transfer in Fluids

Lab Summary

Use a fast response temperature sensor to investigate what happens to the temperature of a solution when two substances of different temperatures are mixed.

Theory

Students investigate what happens to the temperature of a solution when two substances of different temperatures are mixed.

Students investigate the mixing of substances at different temperatures while they:

  • Develop the understanding that energy is a property of many substances and is associated with heat, light, electricity, mechanical motion, and the nature of a chemical
  • Recognize that heat can be transferred through a fluid
  • Learn that heat moves in predictable ways, flowing from warmer objects to cooler objects, until both reach the same temperature
  • Gain skills and confidence in using scientific measurement tools, the temperature and pressure sensors, as well as the graphing capability of a computer to represent and analyze data

Method

Students gain experience conducting the following procedures:

  • Setting up the equipment and work area to measure the temperature of three samples of water
  • Measuring the temperature of a sample of cold water
  • Measuring the temperature of a sample of hot water
  • Measuring the temperature of a mixture of equal volumes of cold and hot water after mixing them
  • Using math skills to average temperatures

Sensors / Equipment Used:

PASPORT Chemistry Sensor

(PS-2170)

Allows students to measure Temperature, pH/ISE/ORP, Absolute Pressure & Voltage in one sensor. For use with PASPORT Interfaces.
