Temperature vs. Speed of Particles Question: Is there a relationship between the temperature of a liquid and the speed that its particles move? Hypothesis:
If I use hot water, then _____________________________________________ If I use cold water, then_______________________________________________
Experimental Design Using cups of hot, cold, and room temperature water, determine what temperature causes the particles in food coloring to move fastest. Independent Variable: __________________________________________ Dependent Variable: ___________________________________________ Control: Room temperature water Constants (ex. Amount of water): _________________________________ Data Cup 1 2 3
Temperature (°C)
Seconds to completely diffuse
Conclusion 1. Was your hypothesis correct or incorrect? 2. In which temperature did the food coloring spread the fastest?
3. Why did the food coloring move the fastest in this temperature?
4. In which temperature did the food coloring diffuse the slowest?
5.
Why did the dye move the slowest in this temperature?
