Explain why atoms move at different speeds depending on whether they are in liquid or solid

Use the Heisenberg uncertainty principle to calculate the uncertainty (in meters) in the position of a honeybee weighing 0.67 g and traveling at a velocity of 0.80 m/s. Assume that the uncertainty in the velocity is 0.1 m/s.

In what order should blood tubes be filled when drawing for multiple tubes? Order of draw?

What is a qualitative observation

A proton moves through a region of space where there is a magnetic field B = (0.45i + 0 38j) T and an electric field E = (3.0 i - 4.2 j) x 10^3 V/m. At a given instant, the proton's velocity is V = (6.0 i + 3.0 j - 5.0 K) x10^3 m/s.

A student performs the following procedure: Procedure 1. Measure 25 grams of an unknown solid. 2. Measure 200 grams of water. 3. Pour the unknown solid and water into beaker, which weighs 50 grams. 4. Stir the solution.

When water is warm it will: * allow for solids and gases to dissolve easier make it harder for solids and gases to easily dissolve allow for gases to dissolve easier, but make it harder for solids to dissolve allow for solids to dissolve easier, but
