Answer 1

1) All matter is composed of very small particles which can exist independently. (ii) Particles of matter have spaces between them. (iii) Particles of matter are continuously moving. (iv) Particles of matter attract each other.

2) By the late 1830s, botanist Matthias Schleiden and zoologist Theodor Schwann were studying tissues and proposed the unified cell theory. The unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells.

3)a- Uniform Velocity-A body is said to have uniform velocity if it covers equal distance in equal intervals of time in a particular direction, however, the time intervals may be small.

b- quantities having both magnitude and direction

c- uniform circular motion is that body moves around a fixed point or on a circular track with uniform speed. When an object is in uniform circular motion, its speed doesn't change. It means that an object will move with constant speed

3) a- 27 celcius b- 300 celcius
