Waters Specific Heat Capacity | Vattens värmekapacitet | Labbrapport
En enklare labbrapport på engelska, där eleven undersöker vattens värmekapacitet (waters specific heat capacity). Resultatet presenteras med hjälp av diagram och tabeller.
Kunde varit mer tydlig - är inte lika säker på engelska som på svenska.
An element heater, a vacuum flask, a thermometer, a set of scales and a chronometer.
Firstly, 0,5kg of water was weighed. The element heater was put into the vacuum flask. Every 30th second a measurement was taken by the thermometer using the chronometer to take the time. The result was documented in a table form. Thenceforth the result was utilized to create a linear function. The whole operation was done 3 times and every experiment was supposed to go up to 70 degrees.
Analysis: The purpose of the experiment was to calculate water's specific heat capacity. To calculate the specific heat capacity of water a certain formula was given. Although the formula wasn't correctly balanced, the formula can be typed in this way instead: C= (P/m) / (ΔT/Δt)
The variable C in the formula is the answer to this experiment, the specific heat capacity of water.
''m'‘ is the mass of the water and ''ΔT'' is the difference in time of a chosen period. Later on the result from the experiment was put into the formula which led to the answer. However the... Köp tillgång för att läsa mer
