REVISION QUESTIONS SCIENCE GRADE 5
. What are the three most common forms of matter
Solids, liquids, gases
If heat is added to a liquid, what state of matter will it be
It will be gas
Which state of matter has tightly packed particles
Solid
. Why is melting ice an example of a reversible change
Water can be frozen back to ice
. Is melting adding or removing heat energy
Removing energy
. What happens to the kinetic energy of the particles if the temperature increases
Kinetic energy increases
. What will happen to the mass of a chocolate bar after it has melted
Mass remains the same
. When a solid is changed to gas, this is called
sublimation
. When the particles are moving faster, it means they are
The temperature increases, kinetic energy increases
. What is deposition
Change from gas to solid without passing the liquid state
. Give an example of Plasma
Plasma is an ionized gas, present in sun, stars, lightning, aurora, neon lights, welding arcs
. Are melting and freezing reversible
Yes, reversible. (S to L, L to G, and S to G are all reversible)
. Are evaporation and condensation physical change
Yes, evaporation and condensation are physical changes
. Which state of matter has the highest density
Solid have the highest density
. Which state of matter has a definite shape and volume
Solids have definite shape and volume
. Which state of matter has no definite
shape but fixed volume Liquids have no definite shape but definite (fixed) volume
. Which state of matter has the strongest force between the particles
Solids have the strongest force between the particles
. Which state of matter has the weakest force between the particles
Gases have the weakest force between the particles
. Which state of matter has the lowest density and lowest mass
Solids have the lowest density and lowest mass
. Which changes of state include adding energy
Give three Melting, Evaporation, and Sublimation
. Which changes of state include removing energy
Give three Freezing, Condensation, and Deposition
. A puddle drying out shows which change of state
Evaporation
. Which state of matter can be compressed and squashed
Gases can be compressed and squashed
. Identify the change of state in a hair dryer being used on wet
hair. Liquid to gas
. If I have 250 grams of butter on a scale, what will be the mass of the butter after melting
250 grams still
. If I have two beakers, Beaker A is 50 degrees and Beaker B is 100 degrees, which beaker will have faster movement of molecules
Beaker B as temperature increases, kinetic energy increases, so particles have more energy to move
What is the best example of sublimation
Solid to gas
. Snow and hail are examples of which change of state
deposition
. Arrange the three states of matter according to increasing force between particles
Gas, liquid, solid
. Arrange the three states of matter according to increasing
speed of particles. Solid, liquid, gas
