What two physical factors affect water potential?
Pressure and solute concentration are the two physical factors that affect water potential. Pressure increases water potential, while solute concentration decreases water potential.
What physical quantity has the unit joule per columb?
The physical quantity that has the unit joule per coulomb is electric potential, which is measured in volts. Electric potential is a measure of the electric potential energy per unit charge at a point in an electric field.
What is energy stored within any physical thing called what?
Potential Energy. What Potential Energy is, is a whole different question
Is potential energy negative in any physical system?
In some physical systems, potential energy can be negative. This occurs when the reference point for measuring potential energy is set at a higher level than the actual energy level of the system.
What is energy stored within any physical thing called?
Potential energy is the energy stored within any physical thing. This energy is associated with an object's position or state, such as gravitational potential energy or elastic potential energy. When an object's position or state changes, potential energy can be converted into kinetic energy.
What is a example of a physical contaminant?
A common example of a physical contaminant is a piece of glass in food. This can occur during food processing or handling and pose a serious health risk if consumed.
Which is a physical contaminant?
A physical contaminant is a foreign object that can be unintentionally introduced into a product, such as metal fragments, glass shards, or hair. Physical contaminants can pose a risk to consumer safety and may result in injury if consumed.
Which physical contaminant could be associated with salmon?
Fish bone
What is contaminant fate?
A similar term is "contaminant transport". It means the path that a contaminant moves from its beginning to its final resting place, and all the physical, chemical and biological processes that might change it on its journey.
Which items is an example physical food contaminant?
bacteria or other rotten food
What are the biological and physical chemical appliction oxidiation and reduction?
The biological and physical chemical application of oxidation and reduction include contaminant reduction and mineralization of organic matter.
Which one of the following contaminantes is a physical contaminant?
A physical contaminant is typically a foreign object that can cause harm or injury when ingested or encountered. Common examples include glass shards, metal fragments, stones, or pieces of plastic. Unlike chemical or biological contaminants, physical contaminants result from human error or mishandling rather than from chemical reactions or microbial growth.
Is a caterpillar found in a case of lettuce a physical contaminant?
Yes, a caterpillar found in a case of lettuce is considered a physical contaminant. Physical contaminants are foreign objects that can be present in food, including insects, hair, and pieces of plastic or metal. The presence of a caterpillar can pose health risks and affect the quality and safety of the food product. It is important to ensure that such contaminants are removed to maintain food safety standards.
What has the author J A Toly written?
J. A. Toly has written: 'Physical model of the dispersion of a radioactive contaminant in the atmosphere above a heat island'
Could a ph-sensitive color indicator be ussed to reveal the presence of a contaminant in a fluid that should be sterile?
Yes, a pH-sensitive color indicator can be used to detect the presence of a contaminant in a fluid that should be sterile. When the contaminant alters the pH of the fluid, causing a color change in the indicator, it indicates contamination. This method can provide a quick visual indication of potential contamination.
Is a metal shaving in a can of peaches a biological contaminate?
No, a metal shaving in a can of peaches is not considered a biological contaminant. Biological contaminants typically include microorganisms such as bacteria, viruses, or parasites. Instead, a metal shaving would be classified as a physical contaminant, which can pose risks of injury or harm to consumers.
Define the terms sanitation and contamination?
Contamination is the presence of a minor and unwanted constituent (contaminant) in material, physical body, natural environment, at aworkplace, etc.
