What describes the structure of protein molecules?
Protein is very high in calsium. It will easily change to level 87
Why does a rigid structure take up more space than a fluid structure?
A rigid structure takes up more space than a fluid structure because the molecules in a rigid structure are locked in place and cannot move past each other easily. In contrast, the molecules in a fluid structure can flow and change position, allowing them to occupy less space and adopt the shape of their container.
What properties change when water freezes to ice?
When water freezes to ice, it becomes less dense, expands in volume, and forms a crystalline structure. Additionally, its molecules slow down and move into a more ordered arrangement, resulting in a solid state.
Is freezing leftovers a chemical change?
Freezing leftovers is a physical change, not a chemical change. When leftovers are frozen, the molecules rearrange to form a solid structure, but the chemical composition of the food remains unchanged.
Changes of state are considered physical changes because?
Physical changes are changes that don't change the structure of the individual molecules. Though heating a liquid to a gas will change how the molecules are bound to each other, the individual molecules will not change. This is contrasted from a chemical change, where the atoms of the molecules are rearranged.
Can molecular structure of moonlight change random?
No. Light is not made of molecules and has no molecular structure to change.
What is it called when the change of state in which a liquid becomes a solid as energy is removed?
The change of state in which a liquid becomes a solid as energy is removed is called solidification or freezing. This process involves the molecules slowing down and coming together to form a more ordered and rigid structure.
Describe the change in the position of molecules that takes as a material melts?
p
How does liquid water change when it becomes ice?
Liquid water changes into ice when it loses heat energy, causing its molecules to slow down and form a crystalline solid structure. This results in a decrease in volume and an expansion of the molecules, leading to the solid state of ice.
How does the motion of molecules change during freezing?
It becomes much more restricted.
Describe the motion of molecules of a substance change as the energy is increased?
As the energy of a substance is increased, the motion of its molecules becomes more rapid and chaotic. This increase in energy causes the molecules to vibrate and move more quickly, leading to an overall increase in temperature and pressure of the substance.
What describes the structure of protein molecules?
Protein is very high in calsium. It will easily change to level 87
How come water doesnt change as it melts from solid to liquid water?
Water does change as it melts from a solid to liquid. That's the change. Its molecules speed up and separate from the lattice structure structure of the ice and become fluid. This is called a physical change because the water molecules themselves do not undergo a change. Solid water and liquid water are still water.If you're talking about temperature, the temperature does not change during the phase change. That's because the heat energy is being used to remove water molecules from the lattice structure. Once all of the water molecules a separated, the temperature can increase.
In physical change can matter change its shape?
If by matter you mean molecules / atoms then no. Physical change is when the look / shape of something is changed but not its chemical structure, chemical change is when the molecules that make up the object n question are changed.
Why is solid usually hard?
A solid has two main forms. Amorphous is where the molecules aren't in a perfect pattern, allowing change to the structure. Crystalline is where the molecules are in a perfect pattern, disallowing change.
What Change is happening as a liquid changes to a gas?
its boiling, the molecular structure of the liquid is changing. The molecules are moving farther apart and moving faster. Gas molecules are fartherest apart and move randomly and rapidly. If you put more air into a balloon it becomes harder because the air molecules are moving faster in a defined space. It explodes when the molecules exert more pressure than the balloon itself can stand.
Is freezing of water a physical?
It's called a physical phase change in such that water molecules rearrange their structure.
