The correct answer is option 4. Placing one drop of food coloring in a cup with 50 mL of water at 10*C; placing one drop of food coloring in a second cup with 50 mL of water at 40*C.
This setup allows the student to compare the kinetic energy (temperature) of two systems with the same volume of water but different temperatures. By observing the rate of diffusion or mixing of the food coloring, the student can make inferences about the connection between kinetic energy (temperature) and the movement of particles.
Which experiment setup would let a student investigate the connection between kinetic energy and temperature?
1. Placing one drop of food coloring in a cup with 50 mL of water at 10*C; placing two drops of food coloring in a second cup with 50mL of water at 10*C
2. Placing one drop of food coloring in a cup with 50 mL of water at 10*C; placing one drop of food coloring in a second cup with 100 mL of water at 10*C
3. Placing one drop of food coloring in a cup with 50 mL of water at 10*C; placing two drops of food coloring in a second cup with 100 mL of water at 40*C
4. Placing one drop of food coloring in a cup with 50mL of water at 10*C; placing one rop of food coloring in a second cup with 50 mL of water at 40*C
