My results summarised


  • For my experiment I did three trials. It took approximately 30 minutes to complete one trial within one day. I started with 20g of salt and went up to 100g. 
  • My results were recorded at the end of each 20 g of salt. From my results it is evident that adding 20 grams of salt into 300 mL of water, the temperature went up about 1.5 °C every time.  
  • My results also backed up my primary research which had stated that the more salt you put into the water the higher the temperature. 
  • My end results were recorded in a table as well as a line graph. 
  • These were my results for my first trial: 20g- 101.5 °C, 40g-103 °C, 60g-105.5 °C, 80g-106.5 °C and 100g-107.5 °C. My second results were 20g-102 °C, 40g-103 °C , 60g-104.5 °C, 80g-106.5 °C and 100g-109 °C. Finally for my third trial my results were 20g-103 °C ,40g-105 °C , 60g-106.5 °C ,80-107.5 °C and 100g-109 °C.
  •  My trials weren’t very different in degrees and were basically around the same numbers. I had noticed that my second and third trials had increased in numbers than the first one. They were much higher numbers such as 107.5 to 109. 
  • For my experiment I also kept getting continuos results for each trial. My investigation is accurate because I did more than one trial. I got constant and very much the same results and my experiment becomes reliable.
