Principle

The specific heat capacity describes the ability of a material to absorb thermal energy. It can be determined by measuring the rate of temperature change if both the mass of the heated substance and the supplied heating power are known.

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 200 ml of water with an electric heating coil and measure the temperature increase as a function of time and examine the electrical power and the amount of heat absorbed by the water.

Learning objectives

The students learn to determine the specific heat capacity of water experimentally.
