The issue of water and sand contour heating contour of time,what the temperature is high.
Test water and sediment materials
Experimental tools beaker of alcohol thermometer stopwatch lights balance
Experimental steps
Balances in the beaker with quantitative said in the sand
Alcohol lamps heating for a period of time
Be careful not too long
Measuring temperature
The same beaker
Said contour of the water
Heating contour time
Measuring temperature
The results of the high temperature sand
Conclusion heating the same time,the sand temperature higher than the temperature of the water.
Do not pay attention to matters boiling water
Alcohol lamps Chuimie not through your mouth.
