To resolve an object in an electron microscope, the wavelength of the electrons must be close to the diameter of the object. What kinetic energy, k , must the electrons have in order to resolve a protein molecule that is 8.60 nm in diameter? Take the mass of an electron to be 9.11×10−31 kg .

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.
