Explanation

When a body is in unstable equilibrium, a slight tilt will cause its center of gravity (CG) to remain above the point of contact, making it prone to toppling over or falling.

This means that the CG is not directly over the point of support, but is still above it, creating a moment that tends to rotate the body further.

Key Points:

• A body is in stable equilibrium after slight tilt if its center of gravity remains above the point of contact.
• A body is in neutral equilibrium when its center of gravity remains at same height.

Explanation

This is a statement of Newton's second law of motion, which states that the force (F) required to accelerate an object is proportional to its mass (m).

Explanation

• When a saturated solution of KCl (potassium chloride) is heated, the solubility of KCl increases, allowing more KCl to dissolve in the solution.
• If the solution is heated to a temperature where all the KCl dissolves, it becomes a supersaturated solution.
• A supersaturated solution contains more dissolved solute than it can hold at a given temperature, making it unstable.

Explanation

• A triple covalent bond is a chemical bond that involves the sharing of three pairs of electrons between two atoms.
• This type of bond is typically found in molecules where three pairs of electrons are shared, resulting in a strong and stable bond.

Explanation

• Bile salts are produced by the liver and stored in the gallbladder.
• They are released into the duodenum (the first part of the small intestine) to facilitate fat digestion.

Explanation

• The energy released (14135 KJ) is equivalent to the energy released from the oxidation of glucose (C6H12O6), which is typically around 2820 KJ/mol.
• To find the number of moles of glucose consumed, you can divide the energy released (14135 KJ) by the energy released per mole of glucose (2820 KJ/mol):
• 14135 KJ ÷ 2820 KJ/mol = 5 mol

Explanation

• Water has its minimum density at 0°C.
• Water has its maximum density at 4°C.

Explanation

• Heat is a form of energy that flows from a region of high temperature to a region of low temperature.
• This flow of energy occurs through the transfer of kinetic energy from particles in motion.

Explanation

Surface Tension:

"The property of the surface of a liquid that allows it to resist an external force,

due to the cohesive nature of its molecules."

Explanation

Aluminium powed + Nitrate Called Ammonal  

Ammonal is an explosive made up of ammonium nitrate and aluminium powder, in which the ammonium nitrate functions as an oxidizer and the aluminium as fuel.

The mixture is often referred to as Tannerite, which is a brand of ammonal.

The ammonium nitrate functions as an oxidizer and the aluminium as fuel.

The use of the relatively cheap ammonium nitrate and aluminium makes it a replacement for pure TNT.
