Explanation:
not ure but hope it helps
All types of energy can be resumed into two basic types of energy which include kinetic energy and potential energy.
<h3>What is kinetic energy?</h3>
Energy is the ability to perform a given work. Kinetic energy is energy in movement, whereas potential energy is stored energy.
For example, plant photosynthesis makes reference to chemical energy (potential energy), popcorn makes reference to thermal energy, etc.
In conclusion, all types of energy can be resumed into two basic types of energy which include kinetic energy and potential energy.

Answer: D. Their ability to fill the available volume in a container. I hope this is right.
Answer : The heat energy required to melt 2 kg of ice was, 667.7 kJ
Explanation :
First we have to calculate the moles of ice.
Now we have to calculate the heat energy.
As, heat energy required to melt 1 mole of ice = 6.01 kJ
So, heat energy required to melt 111.1 mole of ice = 111.1 × 6.01 kJ
= 667.7 kJ
Therefore, the heat energy required to melt 2 kg of ice was, 667.7 kJ
For electricity to flow there must be a flow of electrons or ions present in a system or medium. When electricity is passed in pure water, oxygen does not have d-orbitals or f-orbitals through which electrons may pass. In pure water there are no electrolytic substance, so no ions present in the pure water. Therefore electricity can not pass through pure water. Additionally; water cannot dissociate into OH- and H+ when electricity is passed through pure water.
