What happens to water molecules as ice melts?
the molecules absorb heat and start moving rapidly changing from solid to liquid
Why does it take water longer to heat up than sand?
Sand is a solid, so all the particles are closer together. This means that when heat energy is applied to it, the molecules vibrations can affect the the molecules close to it because all the molecules are so close together. However, in a liquid, the molecules aren't as close together - they're random and just everywhere, with some molecules being quite far apart from another [but still attached to eachother], so it's harder for the vibrations from the heat energy to pass on from one molecule to another.
What properties of matter are affected by heat?
All properties of matter is affected by heat. Only some solid things arent much affected by heat because their molecules are tightly packed and sticked strongly like diamonds and other solid.
How a solid can be changed into a liquid?
1. Heat it up. 2. Reduce air pressure.
What are the differences between freezing and melting?
When you melt something, for instance an ice cube, you are suppling enough heat energy to break intermolecular bonds between molecules so there are enough free molecules to change state. When you freeze water, you are cooling it down enough so that the molecules stop moving enough for intermolecular forces to have an effect, essentially holding the molecules in a structure that, to the eye, is ice. Freezing is the transition from liquid to solid (heat is being lost from the system). Melting is the transition from solid to liquid (heat is being gained by the system)
How does heat affect the molecules of the property solid?
Most usually, heat expands a solid, making it less dense.
What are molecules that are joined in an ordered structure?
When molecules are linked in organized positions has solid results. When heat is absorbed by a solid the molecules vibrate faster and faster.
How does heat affect the movement of molecules in a rubber?
Heat does not affect it. It expands with coolness. It contracts with heat.
What happens to molecules in a solid when heat is applied?
the molecules vibrate more rapidly and the solid expands a little the temperatuer also transfers faster through the solid
Which is a better conductor of heat solid or gas?
solid becaus there are more molecules so they spread the heat energy around quicker
How will the state of matter change when heat is removed from a system?
Heat creates energy, so removing heat will slow down the movement of the molecules in the system. The molecules either go from gas -> liquid -> solid, or straight from gas ->solid.
How molten metal chages into a solid?
A metal is actually solid beforwe application of high heat,a metal becomes molten when the heat is high enough to enable breakage of bonds between molecules of the metal such that the molecules are free to move as in liqiud.so a molten metal becomes solid when molecules form bond again as in solid.
Does the kinetic energy increases when we heat a solid at its melting point?
Of the molecules in the solid : yes. Of the mass as a whole : no.
The molecules of any substance are what to each other?
The molecules of any substance are attracted together. Heat causes the molecules of a solid to separate from each other, making the solid become a liquid.
Why do increase temperature affect how quickly a solid solute dissolves?
Heat increase the speed at which a solid dissolves as it causes the molecules to disintegrate and spread away from each other. Heat will convert a solid into a liquid and eventually into gas.
What happens when a solid a liquid and gas when it changes its state?
Well solid to liquid the heat speeds up the molecules and same for liquid to gas but from liquid to solid the coolant slows the molecules down
What is the effect of heat when dissolving chocolate?
If you look at the atomic structure of a solid, the molecules are held quite tightly with strong forces that prevent the solid from moving about. When you heat a solid such as chocolate, you are breaking these strong bonds and allowing the molecules to move about more freely. So, the more heat you put in, the more chocolate will dissolve.
