What happens to the size of the molecules during a phase change?
During a phase change, the arrangement of molecules changes while their size remains the same. For example, when a solid transitions to a liquid, the molecules rearrange into a more disordered state, but their actual size does not change.
How do intermolecular forces effect of the properties of a substance?
A compound where the molecules are distant from each other is most likely a gas. Liquids and solids haves molecules that are closer together, with solids having the least space between molecules. As the temperature of the compound drops, molecules move closer together. There are exceptions to this rule, water for instance, has more space between its molecules when frozen.
What is the Size of CFC?
The size of a CFC molecule is small, typically containing between two to five carbon atoms, along with chlorine and fluorine atoms. These molecules are small enough to be released into the atmosphere where they can contribute to ozone depletion.
Do gas particles become larger when dry ice changes into carbon dioxide?
The particles change from being tightly held in a solid to being free in the form of a gas; the molecules do not change size.
Are all molecules the same size?
No, molecules come in various sizes. The size of a molecule is determined by the number and arrangement of its atoms. Small molecules like oxygen and water are much simpler and smaller than complex molecules like proteins and DNA.

Why do you think that the eggs membrane will let water to enter but not corn syrup?
water molecules are smaller than corn syrup. the membrane allows a certain size of molecules.
How does the polarity of alcohol molecules change as their size increases?
As the size of alcohol molecules increases, their polarity generally decreases. This is because larger alcohol molecules have more nonpolar hydrocarbon chains that outweigh the polar hydroxyl group, reducing overall polarity.
What is the significance of the size of CO2 molecules in relation to their impact on the environment?
The size of CO2 molecules is significant because it allows them to trap heat in the Earth's atmosphere, leading to the greenhouse effect and contributing to global warming and climate change.
Does the grain size of salt change when mixed in water?
No. the molecules are simply separated from each other and mixed with the water.
What factor least affects a compounds tendency to change state?
The factor that least affects a compound's tendency to change state is the size or mass of the compound's individual particles. Larger or heavier particles generally have a higher tendency to change state due to stronger intermolecular forces.
During physical changes what does matter always retain?
During physical changes, matter always retains its chemical composition, which means the atoms and molecules in the substance remain the same before and after the change. This is because physical changes involve rearranging molecules or changing the state of matter without altering the fundamental identity of the substance.
What is the relationship between the size of carbon dioxide molecules and their impact on the environment?
The size of carbon dioxide molecules does not directly impact the environment. Instead, it is the quantity of carbon dioxide released into the atmosphere that contributes to environmental issues such as climate change and global warming.

Are molecules and X-rays the same size?
No. molecules are smaller.
Water molecules spreading through a membrane with a change in cell size is an example of what?
Water molecules spreading through a membrane with a change in cell size is an example of osmosis. In osmosis fluid passes both in and out of the semipermeable membrane in osmosis, but usually there's a net flow in one direction.
What is hysical change?
phyiscal chage has texture and shape,size,color,odor,volume,mass,weight,and density
