Explanation

Evaporation is the process where liquid turns into gas at temperatures below its boiling point.

It occurs at the surface of the liquid.

It is influenced by factors like temperature and surface area.

Explanation

In the Fahrenheit scale:

• The freezing point of water is 32°F
• The boiling point of water is 212°F

Explanation

• Chemical digestion of proteins starts in the stomach.
• Where gastric juices containing pepsin and hydrochloric acid break down proteins into smaller peptides and amino acids.

Explanation

• Cellulose is the main component of the cell wall in plant cells, providing strength, rigidity, and shape to the cell.
• It is a complex carbohydrate made up of glucose molecules. 
• It is responsible for maintaining the cell's structure and supporting its growth.

Explanation

The ampere, symbol A, is the SI unit of electric current.

It is defined by considering the fixed  value of the elementary charge e as 1.602 176 634 x 1019,

where the unit C is equal to As and the second is defined by Δν Cs.

Explanation

An ammeter is a device specifically designed to measure electric current (in amperes).

Explanation

• Sound waves travel in solvents (such as liquids and gases) in the form of longitudinal waves, where the particles of the medium oscillate back and forth along the direction of propagation.
• This means that the particles move parallel to the direction of the wave, creating compressions and rarefactions in the medium.

Explanation

• In a parallel circuit, each branch has its own path for current to flow.
• If one branch is interrupted, the other branches will continue to operate normally.

Explanation

There are 3 main states of matter:

• Solid (fixed shape and volume)
• Liquid (fixed volume, but takes shape of container)
• Gas (neither fixed shape nor fixed volume)

Explanation

• Sound travels fastest in diamond, with a speed of approximately 12,000 meters per second (m/s).
• This is because diamond has a very high stiffness and density, which allows sound waves to propagate quickly through the material.

The speeds of sound in different materials:

• Air: 343 m/s
• Water: 1433 m/s
• Wood: 3300-3600 m/s
• Brick: 4176 m/s
• Steel: 6100 m/s
• Diamond: 12000 m/s
