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.
Why does ice melt in your hand and make your hand cold?
your body temperature is higher than that of an ice cube's, so your fast-moving molecules in your hand hit the slow-moving molecules in the ice cube, warming it up. the transfer of ice to water is just to let the atoms and molecules move about free-er in liquid form.
What three things do you need to make a fire?
Fuel, oxygen and heat or an ignition source are the components needed for a fire.
Why does water heat up more slowly than land?
The molecules that compose or make up a solid, such as land, need more energy or in this case heat, to move them. The molecules are compact where as in liquid they have more mobility. When a substance heats, its molecules move faster. Since liquid's molecules have more mobility, liquid heats more quickly.
How does heat make things dry when the molecules are actually moving faster not slower?
the water molecules move away, e.g. evaporate
How does conduction heat things?
The vibrating atoms/molecules in the hot sustance make the atoms/molecules in the cooler substance vibrate and this vibration gradually spreads along the substance.
Why does rubbing your hands together make them warmer?
Rubbing your hands together creates friction, which generates heat due to the molecules in your hands colliding and creating energy. This process helps to increase the temperature of your hands and make them feel warmer.

What three things make things make An ATP molecules?
adenosine triphosphate
How does heating water make a train move?
the molecules are moving faster and the electrons are moving to higher levels
How does heat make molecules move?
The heat energizes the molecules.The molecules of air will move here and there as they are free. Molecules of solids vibrate at there place.Due to heat the molecules get energized that is the main thing.
Why do you get heat?
Quite simply, heat occurs because the molecules in an object or substance move very quickly. All matter, or substances, contain molecules which are always in a state of motion, and actions such as movement can make the molecules move faster, creating heat. Heat transfers because it is energy which travels in waves, and when it touches something else, the molecules in the new item or substance also become excited, moving faster and faster to create heat.
What has heat?
heat-is has moving molecules *the main source of heat is the sun * sun or heat has many uses it dries wet clothes,evaporates water and help plants have light to make the plants food which is very important so the plant will grow well and if we know sun is very important to make photosynthesis (making food of a plant) if there is no plant we had nothing to eat
Why does a microwave have a magnetic?
i am not as sure to what a magnetic means but i do know a microwave has a magnetron and the way it heats food is by putting out microwaves that make the water molecules vibrate which warms the item because more moving molecules in an object means heat which makes the food hot
Does alcohol make molecules move?
Heat makes molecules move. Alcohol, if used as a solvent, makes some molecules more mobile.
How is electricity used to make the heater working?
Energy makes molecules rapidly move faster and faster, and when you make molecules move faster you are creating heat. So by using electricity(energy), you speed up the molecules of water, thus creating heat.
