Which substance was able to diffuse through the cellophane?
The substance that can diffuse through cellophane is typically small, nonpolar molecules or water. For example, water can pass through cellophane membranes due to its small size and polar nature, while larger molecules like glucose or starch generally cannot. The permeability of cellophane depends on the size and polarity of the molecules involved.
Can a negative charged balloon pick up paper?
Yes, a negatively charged balloon can pick up small pieces of paper due to the attraction between the negative charge on the balloon and the positive charge on the paper. This phenomenon is a result of static electricity.
Is cellophane toxic if ingested?
Cellophane is not inherently toxic if ingested in small amounts. However, ingesting large quantities of cellophane can lead to a potential risk of intestinal blockage or choking hazard due to its indigestible nature. It's always best to seek medical advice if accidental ingestion occurs.
What is an extremely small particle of matter with no electrical charge?
a neutron, a proton is positively charged and an electron is negatively charged :)
What is a small protein with a high proportion of positively charged amino acids that binds to the negatively charged DNA and plays a key role in it chromatin structure?
Histones are small proteins that have a high proportion of positively charged amino acids. They bind to the negatively charged DNA to form nucleosomes, which help in packaging and organizing the DNA into chromatin structure.
Why does a charged balloon attract on small bits of paper?
The charged balloon creates an electric field around it, which polarizes the small bits of paper, causing them to be attracted towards the balloon. This is due to the interaction between the charged balloon's electric field and the charges within the paper.
When a glass rod is change and is placed near small bits of paper the paper bits are attracted to the rod and then replied explain?
When a glass rod is rubbed, it acquires a positive static charge. The small bits of paper become negatively charged by induction when the positively charged glass rod is brought nearby. Opposite charges attract, causing the paper bits to be attracted to the rod.
Why does a charged balloon attracts small bits of paper?
When a balloon is rubbed against hair or fabric, it becomes charged with static electricity. The charged balloon creates an electric field around it. The small bits of paper are also charged or polarized by the electric field of the balloon, causing them to be attracted to the balloon.
Why does a charged ruler attract small pieces of paper?
A charged ruler attracts small pieces of paper due to the electrical force between the charges. The ruler becomes charged when electrons are transferred to or from it, creating an electric field around it that exerts a force on the neutral pieces of paper, causing them to be attracted to the ruler.
When a glass rod charged its placed near small pieces of paper bitsthe paperbits are attracted to the rodthen repelledexplain?
The glass rod aquires static electricity.the paper bits are negatively charged and the glass rod is positively charged.when it battracts the paper ,the both aquire like charges due to which they both are repelled.
Suggest why the small peice of paper stick to the charged comb?
The small piece of paper sticks to the charged comb because of static electricity. When the comb gets charged by rubbing it against a material like fabric or fur, it gains excess electrons which create a negative charge. The negative charge on the comb attracts the positively charged protons in the paper, causing the paper to stick to the comb.
How do you explain why a charged comb often attracts smaller bits of papers that fly away when they touch the comb?
When the comb is charged, it creates an electric field around it. When the charged comb is brought close to the small bits of paper, it induces a charge in them by polarizing their electrons. Opposite charges attract, so the paper bits move towards the comb due to the attraction between the comb's charge and the induced charge in the paper bits.
When a comb rubbed with dry hair why attracts small bits of paper?
when we rub the plastic scale against the hair it loses the electrons and whenever an object loses electrons it becomes positively charged .When this positively charged plastic scale brought nearer to paper pieces induces charge on it and electrons revolving in discrete orbits are attracted and nucleus is pushed back so that repulsion do not take place.
A plastic rod will pick up small pieces of paper when it has been rubbed with a cloth?
When the plastic rod is rubbed with a cloth, it becomes charged with static electricity. The rod becomes positively charged by stripping electrons from the cloth, making it attractive to the small pieces of paper which are negatively charged. This electrostatic force allows the plastic rod to pick up the small pieces of paper.
Why don't the attractive and repulsive forces cancel outwhen a negatively charged rod is brought close to some small pieces of neutral paper. The positive sides of molecules in the paper are attracted?
The The molecules in the paper will orient themselves so that the positively charged sides point towards the rod and the negatively charged sides point away. Since the electrical forces decreases with increasing distance the nearer positive charges experience a stronger force than the more distant negative charges. As a result, the net force will be one of attraction.
Why does a comb run through dry hair and attract small pieces of non conductive paper.?
When a comb is run through dry hair, it becomes charged with static electricity due to the friction between the comb and hair. The non conductive paper is attracted to the comb because of this buildup of static electricity, causing the paper bits to stick to the comb.
