Specific heat capacity of water with Cobra SMARTsense
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.
