Solution
It seems like there are multiple questions here. I'll answer them one by one.
Question 12: The factors that would increase the rate of diffusion of sugar in tea are stirring the tea with a spoon and the temperature of the tea. Stirring the tea helps distribute the sugar more evenly and quickly, while a higher temperature increases the kinetic energy of the sugar molecules, making them move faster and thus diffuse quicker. Covering the mug with a lid or using sugar cubes instead of granules would not increase the rate of diffusion.
Question 13: Blank 1: The state of matter just before a substance boils is liquid. Blank 2: The state of matter just before a substance melts is solid. Blank 3: Aluminium at 20 ºC will be in a solid state. Blank 4: The state of matter responsible for the Northern Lights is plasma.
Question 14: False. During condensation, gas particles slow down and attraction forces between particles increase.
Question 15: True. The smaller the size of a particle, the higher the diffusion rate. This is because smaller particles have a larger surface area to volume ratio, allowing them to move and spread out more quickly.
