(PICK ANY ONE)
Diffusion is the spontaneous movement and mixing of particles of one substance with the particles of another substance due to their continuous random motion.

Diffusion is the movement of particles from one place to another as a result of their random motion until they become uniformly distributed.

Diffusion is the process by which particles of a substance move from a region of higher concentration to a region of lower concentration until they are evenly distributed.

(i) A solar energy collector is used to collect and convert solar energy into heat, whereas a black body is an ideal body that absorbs all incident radiation.

(ii) A solar energy collector is a practical device used in everyday applications, whereas a black body is a theoretical concept used in physics.

(iii) A solar energy collector is not a perfect absorber of radiation, whereas a black body is a perfect absorber of all radiation falling on it.

(iv) A solar energy collector is designed mainly to absorb radiation from the Sun, whereas a black body absorbs radiation from all sources.

(v) A solar energy collector may reflect some radiation, whereas a black body reflects none.

(vi) A solar energy collector converts absorbed energy into useful heat for practical use, whereas a black body is mainly used as a standard for studying thermal radiation.

(vii) A solar energy collector is made from real materials such as metal plates and glass covers, whereas a black body is an idealized object that does not exist perfectly in nature.

(viii) A solar energy collector has practical applications such as water heating, space heating and crop drying, whereas a black body has no direct practical heating application.

(ix) A solar energy collector has an efficiency less than 100%, whereas a black body has an absorptivity of 100%.

(x) A solar energy collector is designed to reduce heat loss and retain heat, whereas a black body is not specifically designed for heat retention.

(6a)
(PICK ANY ONE)
Hard magnetic material is a magnetic material that can be permanently magnetized and retains its magnetism for a long period of time even after the magnetizing force is removed.

Hard magnetic material is a material with high magnetic retentivity and coercivity, making it difficult to demagnetize once it has been magnetized.
