Absolute Zero Aim iTo find the relationship between Temperature and Volume when heating a gas iiTo find the of absolute zero temperature ie 0 Kelvin -27315 Variables Dependant Variable Volume Independent Variable Temperature Hypothesis The volume of the water will increase as temperature increases since the distance of the particles in the water between each other increases making the water expand increasing the volume of the water Apparatus Materials 1000mL glass beaker tap water 0 to 110-glass tube thermometer open ended glass capillary tube ice cubes Data Collection TV 14195 2520 30202 35204 40206 45207 50208 55209 6021 65211 70212 75213 80215 85218 9022 600 ml of water For open ended glass capillary tube 1 unit 1mm Conclusion and Evaluation The results support the hypothesis stated above as the temperature of the water rises the volume increases as well The volume does not increase proportionally with the temperature The graph shows that the results I measured were not very accurate since the absolute zero I obtained after drawing the line of best fit is -435 instead of the accepted value of -27315 there is a gap of 16215 between those two values The graph shows how inaccurate my readings were the data points do not increase constantly instead the slope one would obtain if one were to draw a line connecting those pints would approach 0 in other words the line would become horizontal similar to a cubic function There were many errors which manipulated this experiment First one is as always human error the use of analogue measuring devices meant that one had to read off the values with the human eye and since humans tend to round values off to make them simpler the readings get manipulated It is also difficult or even impossible to read off the volume of the open-ended glass capillary tube at
