Attraction between a cation in one element and an anion in the other element
Answer:
A compressed spring
Explanation:
A compressed spring has potential energy only and no kinetic energy.
This is because kinetic energy is only possessed by particles in motion.
Energy in a compressed spring= -1/2kx² where x is the displacement.
In this equation there is no velocity so there is no kinetic energy.
Answer:
4- A material that transfers heat energy more easily than another material will experience a greater rate of thermal energy loss than an object that does not transfer heat energy easily.
Explanation:
Thermal energy loss has to do with loss of heat energy by a body to another body or its environment. The aim of the process is usually the attainment of thermal equilibrium between the body and its environment.
On a cold day, a material that transfers thermal energy more easily will loose thermal energy faster than an object that does not transfer thermal energy. The rate of heat transfer of a body determines its rate of loss of thermal energy.
the molar mass is how many grams it takes to make a full mole. The number in carbon 12 tells us that it takes 12 g to makes a mole, so one half of that would be <u><em>option d, 0.5</em></u>.
