Kinetic Theory of Matter
Preguntas del test (12)
1What does the kinetic theory of matter state?
- AAll matter is made up of very small cells that are in constant motion
- BFor every action there is an equal and opposite reaction
- CThe particles of a substance will stay at rest unless heated
- DAll matter is made of small particles that are in continuous random motion
2Which state has the least densely packed molecules?
- ASolid
- BLiquid
- CGas
- DPlasma
3Have a fixed volume
- ASolid
- BLiquid
- CGas
- DAir
4Have a fixed shape
- ASolid
- BLiquid
- CGas
- DPerfume
5How solids move around
- AOsmosis
- BVibration
- CExtremely quickly
- DIn a straight line until it hits the walls of the container
6Why does a solid expand upon heating?
- AThe mean size of each molecule expands with each change in degree Kelvin
- BThe air between the molecules exert a pressure that is equal in force to that of the solid molecules
- CIncreased vibration causes molecules to move away from forces of attraction, therefore occupying more space
7When the temperature of a solid increases then
- AThe volume increases
- BThe volume decreases
- CThe density increases
- DThe density decreases
- EThe mass decreases
- FThe mass increases
- GNothing at all changes
8Not easily compressed
- ASolids
- BLiquids
- CGases
9Shape affected by shape of container
- ASolids
- BLiquids
- CGases
10Why does't latent heat of fusion cause change in temperature
- AThe liquid is not being heated at all
- BPotential energy changes instead of kinetic
- CIS THIS A TRICK!?! Of course it changes temperature
- DNot enough energy is absorbed
11True of Evaporation
- ASurface phenomenon
- BOccurs only at a specific temperature range
- CChange from liquid to gas
- DIncreased when the surface area is increased
- ETemperature does not affect it all
- FBreeze increases the rate of evaporation
- GCauses cooling of surface
12True of Boiling
- ASurface phenomenon
- BOccurs only at a specific temperature
- CChange from liquid to gas
- DThe entire liquid is at 1 temperature
