Heat Transfer in Fluids

Featured in PASCO’s Middle School Science Teacher Guide

Lab Summary

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

 

Theory

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.
