Diagram shows the process of diffusion in liquid. After a few hours, the whole test tube of water becomes purple in color. which of the following statements explain the observation?
Potassium manganate(VII) is more denser than water
Water diffuse among potassium manganate(VII)
Particles of potassium manganate (VII) are tiny and discrete that move randomly
Particles of potassium manganate (VII) move randomly in between the water particles from low concentration to high concentration
Rate of diffusion will be affected by:
[you can choose more than 1 answer]
State of matter

The reaction between ammonia and hydrogen chloride gas will produce a white fume. Which statement is correct about this experiment? Given that RAM for N: 14, H: 1, Cl; 35.5. [there will be more than one answer]
the white fume is ammonium chloride
Ammonia moves faster than hydrogen chloride gas
Rate of diffusion for both ammonia and hydrogen chloride in the air are same because both of them are gases
White fume will be formed at S
White fume will be formed at R

Which statement is FALSE about gas J at room temperature? [you can choose more than 1 answer]
Exist as solid
Exist as gas
Type of particles are molecules
Type of particles are atom
Exist as liquid
Which of the following is true about the curve?
{you can choose more than 1 answer]
At Q, solid X begins to melt
At PQ, particles release heat to the surrounding
The melting point is Y 0C
At QR, particle exist as solid and liquid
At RS, particles exist as liquid
Which of the statement is correct about solid Y when heated?
[You can choose more than 1 answer]
Heat energy is absorb by the particles
Kinetic energy of particles increases
Particles moves more faster
at QR, temperature remain unchange because heat energy release to surrounding is exactly balance by heat energy liberated to form the forces between particles.
Kinetic energy of particles decreases
Diagram show the cooling curve of gas X. Which statement is true?
[You can choose more than 1 answer]
From 0 to t1, heat energy is absorbed
From t1 to t2, forces between particles are overcome
From t2 to t3, kinetic energy of particles increased
From t3 to t4, the heat energy released or liberated to form the forces as liquid turn into solid is equal to the heat energy lost to the surrounding
none above
