Explanation

The Frontal Lobe (part of the Cerebrum) controls reasoning, planning, and problem-solving.

More Details
Cerebellum → balance & coordination,
Medulla → involuntary actions,
Cerebrum → higher thinking functions, divided into 4 lobes (Frontal, Parietal, Temporal, Occipital).

Explanation

• This core concept is known as Boyle's Law.

  • Relation: Pressure ∝ 1/Volume
  • Pressure ↑ → Volume ↓
  • Pressure ↓ → Volume ↑
  • They have an inverse relationship.
  • Formula: P_1V_1=P_2V_2
  • This means Pressure × Volume = Constant 

Explanation

Periods in the periodic table are horizontal rows (left to right).

There are 7 periods in total.

Explanation

• Wavelength is the distance between two consecutive points on a wave that are in phase.
• It is typically denoted by the symbol λ (lambda).

Key Points:

• Time period (T) is the time taken by the wave to complete one oscillation.
• Frequency (f) is the number of oscillations per unit time.
• Amplitude (A) is the maximum displacement of the wave from its equilibrium position.

Explanation

Neutral equilibrium is a state where the body is balanced, but the slightest disturbance will not cause it to return to its original position or topple over.

In this state, the center of gravity (CG) remains at the same height, regardless of the slight tilt or displacement.

Key Points: 

• A body is in unstable equilibrium after slight tilt if its center of gravity remains above the point of contact.
  
• A body is in stable equilibrium after slight tilt if its center of gravity remains above the point of contact.
  

Explanation

• Filtration is the process of separating an insoluble solid from a liquid by passing the mixture through a filter paper or a porous material.
• The solid particles are retained by the filter.
• While the liquid passes through, resulting in a clear separation of the two.

Explanation

The melting point of ice at normal atmospheric pressure is 0 °C (zero degrees Celsius).

Key Points:

• 0 K (zero Kelvin) is equivalent to -273.15 °C, which is absolute zero, the lowest possible temperature.
• 100 °C is the boiling point of water at normal atmospheric pressure.

Explanation

Explanation

• As temperature increases, the heat energy of a substance also increases.
• This is because temperature is a measure of the average kinetic energy of the particles in a substance, and as temperature increases, the particles gain kinetic energy and therefore heat energy.

Explanation

• Reverse Osmosis (RO) is a water purification technology that uses a semipermeable membrane to remove ions, molecules, and larger particles from drinking water.
• This membrane has tiny pores that allow water molecules to pass through, but block larger particles and impurities.
