Heating of various liquids with Cobra SMARTsense

Principle

The absorption of thermal energy depends on the specific heat capacity of a material. Thus, for the same amount of energy per time (heat output), a material with a higher heat capacity needs more time to reach a certain temperature for the same amount of material.

Benefits

• Particularly understandable and didactically prepared description of the experiment (relevance to everyday life etc.) including protocol questions
• Future-oriented teaching: Integration into digital science lessons with tablets
• Increased motivation of students by using the intuitive measureAPP
• Increase of media competence

Tasks

The students heat 100 g and 100 ml of water and glycerine with an electric heating coil and measure the temperature increase as a function of time.

Learning objectives

The students analyze the heating process of glycerine in comparison with water.
