Answer. Metals are excellent conductors because the atoms in a metal form a matrix through which their outer electrons can move freely. Instead of orbiting their respective metal atoms, they form a "sea" of electrons that surrounds the positively charged atomic nuclei of the interacting metal ions
The liquid particles would have moved randomly because of the increase in thermal energy. They would move randomly and would be floating in the bottle moving randomly. The liquid would turn into gas form. Meaning that you would have water particles floating in the bottle moving randomly.
Answer:
40.7 kJ
Explanation:
Applying,
q = c'n.................. Equation 1
Where q = Thermal Heat, c' = Heat of vaporization of water, n = number of mole of water.
But,
n = mass(m)/Molar mass(m')
n = m/m'............... Equation 2
Substitute equation 2 into equation 1
q = c'(m/m')............. Equation 3
Given: c' = 40.650 KJ/mol, m = 18.02 g
Constant: m' = 18 g/mol
Substitute into equation 3
q = 40.650(18.02/18)
q = 40.695 kJ
q ≈ 40.7 kJ
Those materials were PLASTIC,PLA,GLASS,SILVER,TITANIUM,STEEL,WAX,PHOTOPOLYMERS, and POLYCARBONATE
