Answer:
A. Energy
Explanation:
You can change energy from one form to another when you lift your arm or take a step. Energy is used to move matter. In this scenario, the matter would be you.
Ammonia is a weak base because it produces hydroxide (OH-) ions in solution.
Ammonia is a weak base because it produces hydroxide ions (OH-) in solution.
When ammonia dissolves in water, it accepts a proton from water, forming the ammonium ion (NH4+), and leaves hydroxide ions behind. This partial dissociation results in a small concentration of hydroxide ions, causing the solution to be slightly basic.
Unlike strong bases, which fully dissociate and release a large number of hydroxide ions, ammonia's limited ability to produce hydroxide ions makes it a weak base.

Friction causes kinetic energy to be converted into thermal energy.
Friction causes kinetic energy to be converted into thermal energy, among other forms of energy. When an object is in motion and experiences friction, the work done by friction is negative, which reduces the object's kinetic energy. This converted energy is often released as heat.
