Specific Heat Summative
STAGE 1 PHYSICS
ASSESSMENT TYPE 1: INVESTIGATIONS FOLIO
PRACTICAL INVESTIGATION 2: SPECIFIC HEAT
PURPOSE
This assessment provides the student with the opportunity to demonstrate their ability to: formulate hypotheses and identify variables conduct an investigation collect, analyse and interpret data, and form conclusions evaluate results communicate your understanding of the physics concepts relating to the speed of sound in air
DESCRIPTION OF ASSESSMENT
Students will measure the energy given out by a Bunsen burner over a two minute period by measuring the temperature change within varying masses of water.
ASSESSMENT CONDITIONS
The practical is to be completed under supervision in a double lesson.
The students will write a thoroughly detailed experimental report where all variables and experimental procedures will be discussed in detail. Results are to be communicated in table and graph form with a thorough analysis of the experimental procedure and results to follow.
Manipulation of apparatus, safety, (Investigation) and skills in individual and collaborative work are assessed during the implementation of the investigation.
Students will have two days after completing the experiment to formally write up their experimental report for submission
YEAR 11 PHYSICS: SPECIFIC HEAT CAPACITY Name: Changyu Liu
BACKGROUND
If heat transfers to an object, the object’s temperature rises (assuming the phase doesn’t change). However, the magnitude of temperature rise is due to its specific heat capacity. Specific heat capacity is the thermal energy required to raise the temperature of a body of mass 1 kg by 10C. This relationship can be expressed in an equation: Q=mc∆T. Water is a substance with a specific heat capacity of 4.186 joule/gram °C and is capable of storing energy between molecules. In this experiment, the energy change within a mass of water can be determined and this value can be used to determine the
