What causes the particles of a substance to lose thermal energy?
The particles in a substance lose thermal energy as the temperature decreases, because the particles are moving and vibrating less.
What causes the particles of a substance to evaporate?
The paticles gain energy.
Does each substance has particles?
tiny particles
Why does ferromagnetic substance become paramagnetic on heating?
Heating a ferromagnetic substance causes the heat to disrupt the magnetic particles thatÊpoint in the same direction and therefore it becames paramagnetic which is barely magnetic at all.
What happens to the particles when the substance changes shape?
yes! particles of a substance assume different shapes and sizes
What causes the particles of a substance to lose thermal energy?
The particles in a substance lose thermal energy as the temperature decreases, because the particles are moving and vibrating less.
What causes the particles of a substance to evaporate?
The paticles gain energy.
What causes rain to start?
Moisture in the atmosphere always exists, but when it cools sufficiently it can condense around small particles and pour down. maybe
Heat is what in motion?
As energy is added to a substance, the particles that make up the substance vibrate faster. This is what causes substances to change state (solid to liquid to gas). As the particles move faster, the structure changes.
Why are few or no clouds in the troposphere?
There are fewer particles for water to condense to.
Can water be evaporate or condense if its continuous or not made of particles?
It is actually impossible for water to condense or evaporate if it is continuous and not made of particles because these what make water to be condensed and evaporated in the first place.
What happens to particles of water when freeze?
The vibration of the atoms slows and they condense together.
What happens to water particles when freezing?
The vibration of the atoms slows and they condense together.
Why does dust particles present in the air help water vapour to condense?
somehow
Why does water vapor need solid particles in the atmosphere to form clouds?
Particles are needed because then the water vapor can condense on them
Heat causes a gas to condense to a liquid?
Cold (lack of heat) does. Heat causes a liquid to become a gas. Gas>Liquid>Solid.
What effect does the speed of molecules have of matter?
The speed of the particles in a substance changes when the temperature changes. Heating the substance causes the particles to speed up, while cooling causes the particles to slow down.
