What else can I help you with?
What causes certain liquids to float above others?
the density of each of the fats. the higher density, the lower it will be in a mixture
What causes ocean tides to reach higher up on a shore at certain times of day than at others?
The moon's gravity and Earth's rotation
Why do materials get hotter than others?
Materials melt when they are heated past a certain temperature due to the energy in the molecules of the object. As heat is put into them, they gain energy and begin to move. Eventually, the energy becomes too great and they begin to move apart, preventing the object from maintaining its solid form.
Why do some mountains have snow and others not?
because some are higher than others
What are the name of some heatproof materials?
Nothing is 100% heat proof, all materials eventually vaporise or disintegrate with sufficient heat. Aluminium, Silicon and magnesium oxides are often used for the manufacture of refractory materials for kilns Aerogel is not refractory, but it is an extremely good insulator.
How do engineered materials differ from natural materials?
Engineered materials can differ from natural materials in many ways. Engineered ones are made for specific purposes, some to have more tensile strenght like steel and kevlar, others to be more ductil like the elastomers, others to resist to higher temperatures like the ceramics on the space shuttle, others to conduct electricity like silicon based transistors, and so on. They also differ on composition. Engineered materials can be a mix of natural materials (and by this i mean that occur in the nature without human intervention) and man-made, or only man-made materials.
Why can some materials have a higher resistance than others?
because of the gravity of the earth -Jade
Can metal melt in a home fire?
Yes, metals can melt in a home fire if the fire reaches temperatures high enough to exceed the melting point of the metal. The melting point of different metals varies, with some requiring higher temperatures to melt than others. Items made of materials with lower melting points, such as aluminum, may be more likely to melt in a typical home fire compared to those made of materials with higher melting points, like steel.
Why do some people have higher body temperatures than others but they don't have fevers?
Yes, it may depend on what they are wearing or what temperature the room is where they are
Do some balls bounce more then others?
Yes, some balls bounce more than others due to differences in their material composition, air pressure, and elasticity. Materials like rubber typically have higher bounce compared to materials like foam. Additionally, balls with more air pressure or higher elasticity will generally bounce higher.
Do all materials melt at the same temperature?
No, different materials have different melting points based on their molecular structure and composition. Some materials have high melting points, such as metals, while others have lower melting points, such as plastics or ice.
Would it temperature be higher or lower than the temperature of Earth?
It depends on the specific planet in question. Some planets may have higher temperatures than Earth (such as Venus with its extreme greenhouse effect), while others may have lower temperatures (such as Mars which has a thin atmosphere leading to colder average temperatures).
How do different materials respond to heat?
Different materials respond to heat in various ways. Some materials expand when heated, while others contract. Some materials conduct heat well, allowing it to flow through easily, whereas others are poor conductors, leading to slower heat transfer. In addition, some materials may change their chemical or physical properties when exposed to high temperatures.
Why are ecological footprints higher in some countries and lower in others?
Some industrialize, which causes mining and pollution, and some do not.
What causes certain liquids to float above others?
the density of each of the fats. the higher density, the lower it will be in a mixture
Why crystalline materials are opaque?
Not all crystalline materials are opaque, for instance diamond and many others. Some crystalline materials are opaque, it's because they absorb white light, which causes a gap (from IR up to UV) in the transmission spectra.
Do some materials hold onto electrons more tightly than others when charging by rubbing to occur?
Yes, some materials hold onto electrons more tightly than others. This property is known as electron affinity, and materials with higher electron affinities tend to hold onto electrons more strongly when charged by rubbing. Materials like rubber or wool have higher electron affinities compared to materials like silk or glass.
