Question 1:
Diagram below shows the changes in the state of matter of a substance.
Based on the Diagram,
(a) name the processes R, S and T using the following information. [3 marks]
(b) What happens to the kinetic energy of the particles in the substance during process R? [1 mark]
(c) What happens to the movement of the particles in the substance during process S? [1 mark]
(d) Draw the particle arrangement in X in the box provided below. [1 mark]
Answer:
(a)
R: Melting
S: Freezing
T: Condensation
(b) During melting, the kinetic energy of the particles increases.
(c) During freezing, the particles slowing down in their motion and form a pattern, becoming a solid.
(d)
