Explanation

• Copper-64 is used for the diagnosis and treatment of Wilson's disease.
• It helps in imaging and radiotherapy due to its radioactive properties.
• It allowing for the assessment of copper metabolism and liver function in affected patients.

Explanation

• The incorrect statement about suspension is: The suspension is transparent and clear

Suspensions are typically characterized by:

• Being heterogeneous mixtures
• Having dispersed solute particles
• Having varying color and appearance throughout
• Being translucent or opaque

Explanation

• The solution is a homogeneous mixture
• In a solution the particles of solute and solvent are mixed
• The colour and appearance are same in every part of the solution
• The solution is clear and transparent

Explanation

A compound is a pure substance that contains only one type of molecule made up of atoms of more than one element.

Examples of compounds:

• Water (H2O) - Compound of Hydrogen and Oxygen
• Common salt (NaCl) - Compound of Sodium and Chlorine
• Washing soda (Na2CO3) - Compound of Sodium, Carbon, and Oxygen
• Carbon dioxide (CO2) - Compound of Carbon and Oxygen
  
• Sugar (C6H12O6) - Compound of Carbon, Hydrogen, and Oxygen

Explanation

• Solids have a fixed shape and a fixed volume.
• It meaning their particles are closely packed and have a regular arrangement.

Explanation

• Solids can be converted into liquids by heating, a process known as melting.
• This occurs when the particles of the solid gain enough energy to break free from their fixed positions and start moving freely, resulting in a liquid state.

Explanation

• When salt is added to pure water, the boiling point of the solution increases. This is known as boiling-point elevation.
• The boiling point of a solution is higher than that of the pure solvent (water) because the dissolved salt particles disrupt the formation of vapor bubbles, requiring more energy to overcome the surface tension and escape the solution as vapor.

Explanation

• Chlorofluorocarbons (CFCs) are not flammable and toxic.
• They are actually non-flammable and non-toxic, but harmful to the environment due to their role in ozone depletion and climate change.

Explanation

The Boltzmann distribution is a probability distribution that describes how the energy of a system is distributed among its possible states. It is commonly used to describe the behavior of ideal gases, and is given by the equation: f(E) = (1/Z) * e^(-E/kT)

where:

• f(E) is the probability of finding the system in a state with energy Z is the partition function, which is a normalization constant
• E is the energy of the state
• k is Boltzmann's constant
• T is the temperature of the system.

Explanation

Magnetic susceptibility (χ) is indeed measured:
