Question

Is there a difference between heating 50 mL of water to a given temperature, and heating 100 mL of water to the same given temperature but then removing 50 mL?

Answer 1

Yes there is a difference. What specific variable are we observing here?

Answer 2

The amount of thermal energy, the number of water particles, or the speed of the particles

Answer 3

If we are looking at the final 50 mL, then it will be the same in both cases except for the number of water particles. There will be fewer water particles in the final 50 mL of the second situation than the first, because water expands as it heats up.
