Explanation:
A reaction between colorless substances can produce a colored precipitate by formation of new ionic compound.
<h3>What is an ionic compound?</h3>
An ionic compound is a compound that is made up of two elements, one metal and the other non metal, which are held together by an ionic bonding.
When reaction occurs between two colourless substances, colored precipitate results by formation of new ionic compound.

all of the absorbed energy is converted to kinetic energy
Explanation:
When a gas is heated, all of the absorbed energy is converted to kinetic energy. This is because, according to the kinetic theory of gases, the average kinetic energy of gases is directly proportional to temperature.
- As the gas absorbs more heat, the potential energy it carries converted to kinetic energy.
- Potential energy is the energy at rest of a body
- Kinetic energy is the energy due to the motion of the particles of a medium.
- As more heat is added to a body, the kinetic energy continues to increase significantly.
- Eventually, all the absorbed energy is converted to kinetic energy as the gas expands more.
