Does a gas or liquid heat that its molecules move away from each other?
gas heats up and then the molecules spread away from each other, NOT liquid!
What could cause liquid molecules to separate into gas molecules?
Heat!
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
Why does heat turn liquid H2O into gas?
This is an incredibly complicated question; I recommend looking up evaporation in wikipedia. A brief, oversimplified answer is that there are attractive forces in H20 (water) molecules that hold it together, or else they would be separated (and thus be gas). Heat (thermo-kinetic energy) is actually vibrations in the molecules. Evaporation occurs when because of heat; basically the heat is shaking the molecules too hard for them to continue staying together.
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 does a hot air balloon go up?
The more you heat a gas the more it's molecules spread out, hence the lighter it gets.
What three things affect airpressure?
Heat, number of molecules, atmospheric pressure and volume Volume * Pressure = molecules * molar gas constant * Heat
What is heat transfer in condensation?
It's complicated and hard to explain, but I'll try my best. Evaporation occurs when a liquid changes to a gas, but only on the surface of the liquid volume. The gas molecules transfer heat to the liquid molecules. An unequal distribution of heat causes some liquid molecules to become gas molecules. It is random and uneven. Energy from the sun also spawns evaporation. When evaporation does happen, the molecules that leave the liquid body takes a lot of heat with it, therefor the average temperature of the liquid decreases. Evaporation depends on heat, humidity, and air movement.
How does heat change the state of water?
heat does affect water cause the moleculilis that soread to each other
How does heat affect the molecules in a substance?
They rapidly vibrate. Yes, they do, but how rapidly depends on the amount of heat (kinetic energy) added to the molecules. If solid, they will eventually melt depending on which solid and what its melting point is. If liquid, they will eventually become a gas or vapor, and a gas will expand indefinitely into the atmosphere if not contained within something. Think of water: ice heats to liquid water which in turn becomes steam (vapor) which goes out into the atmosphere unless it is contained. If the container cannot expand and the water vapor (or any other gas) continues to be heated, eventually the gas will cause the container to explode because the internal pressure will exceed the ability of the container to hold it.
How does the speed of molecules of gas change when heated?
The speed of the molecules speeds up when the gas is heated.
What happens when evaporation occurs?
When heated up, water molecules (and most molecules in general) will speed up, and start moving quickly. When they reach a certain heat, they turn into gas. It's quite simple.
