What substance has a melting point of 1074 K conducts electricity when dissolved in water but does not conduct electricity in the solid phase?
Ionic solid...I'm assuming that this is an online homework question, and the correct answer is "An ionic solid"
What happens to the particles of a ionic solid and a molecular solid when each mixes with water?
they desolve
Is it true when an ionic solid mixes with water its ions repel water molecules?
yes
When table salt is added to water the ionic compound dissolves. Does this represent a physical change or a chemical change?
Dissolution is considered a physical process.
What is the name when a liquid changes to a solid?
It solidifies, gels, cogagulates, sets, hardens or crystalizes. For water (specifically) it freezes
What is mixture of solid in water is make?
By dissolution of this soluble solid in water.
What is the word when a solid is dissolved in water?
This phenomenon is called dissolution.

How dissolve an ionic solid in water you must first disrupt the ionic bonds holding the ionic lattice together?
in order for an ionic solid to dissolve, the ionic bonds must break through the reaction with water. So yes, what you said is correct. For example a solid NaCl is mixed with water: H20 + NaCl (s) --> Na+ + Cl- + H30+ + OH-

yes
Is sugar water ionic or covalent?
Sugar is a molecular solid. A solution of sugar in water is neither ionic or covalent, but rather a homogeneous mixture.
What bonds are easily disrupted in aqueous solution?
Ionic bonds readily disassociate in aqueous solutions. Table salt, or sodium chloride with the molecular formula of NaCl breaks up into Na+ and Cl- ions in these solutions.

Dissolution is considered a physical process.
Which interactions and processes contribute to the dissolution of ionic compounds in water?
The process of providing energy to break ionic bonds and allow soluble ionic compounds to dissolve in water?
Do Ionic compounds have poor or good conductivity?
Ionic Compounds have poor conductivity when it is solid. Ionic Compounds have great conductivity when it is either dissolved in water or is melted
