Answer:
4) how charged the object creating the field is and the distance between the two charged objects
All three of them i know i already did that
Answer:
The molecules absorb heat and acquire more kinetic energy.
Explanation:
In a solid, the solids only vibrate about their mean positions but do not translate. When energy is supplied to the molecule in the form of heat, the molecules vibrate faster. Eventually, they acquire sufficient energy to leave their mean positions and translate. Hence the solid crystal collapses.
When ice is heated, water molecules acquire sufficient kinetic energy to translate. The intermolecular bonds are gradually broken in the solid framework as heat is absorbed. The heat required for this is known as the latent heat of fusion.
The temperature remains constant until phase transition is over, then temperature rise resumes.
The reaction equation represents the mole number ratio. So the hydrogen is 8/2=4 mol. Oxygen is 64/32=2 mol. So the water is 4 mol. The mass of water is 4*18=72 g. Or if it is confirmed that they are completely reacted. You can simply add them up.
