Why put a lid on the container used to study mass of ice and water?
Putting a lid on the container used to study the mass of ice and water helps to minimize heat exchange with the surrounding environment, ensuring that the system remains thermally isolated. This reduces the risk of evaporation and heat loss, leading to more accurate measurements of mass and temperature. Additionally, it helps to prevent contamination from external substances, which could affect the results of the experiment.
What is a membranous enclosure within a cell that contains substances isolated from the protoplasm such as dissolved acids?
A membranous enclosure within a cell that contains substances isolated from the protoplasm, such as dissolved acids, is known as a vacuole. Vacuoles serve various functions, including storage of nutrients, waste products, and maintaining turgor pressure in plant cells. In addition to acids, they can also hold other substances like salts, enzymes, and pigments, contributing to the cell's overall metabolism and function.
Is a mixture always a chemical combining of substances?
Any particular isolated sample of a mixture has a definite chemical composition, but the general idea of a mixture, even of the same materials, implies variability in possible chemical composition.
What organism is unicellular and was isolated from a very unusual environment?
The organism you are referring to is likely a extremophile, such as a type of archaea or bacteria, that was isolated from a unique environment like deep-sea hydrothermal vents, acidic hot springs, or ice caps. These organisms are unicellular and have evolved to thrive in extreme conditions that are inhospitable to most other life forms.
Why are aquariums considered micro ecosystems?
Because they are designed to be isolated 'copies' of the natural environment that the fish and other aquatic creatures would be found in.

System classification and their primary characteristics?
Systems can be classified as open, closed, or isolated. Open systems exchange both matter and energy with their surroundings, closed systems only exchange energy, and isolated systems exchange neither. These classifications are based on the extent of interaction between the system and its environment.
When a system is exchanges energy with the environment outside the system it is called?
A closed system or an open system. An open can also exchange matter. An Isolated system can exchange neither.
Is a motorcycle in a garage an example of an isolated system?
A motorcycle in a garage is not an example of an isolated system. An isolated system is one that does not exchange matter or energy with its surroundings. In this case, the motorcycle can exchange heat with the garage environment and may also be influenced by factors like humidity or air pressure. Therefore, it is more accurately described as a closed system rather than an isolated one.
What isolates the cytoplasm from the external environment?
The cytoplasm is isolated from the external environment by the cell membrane, also known as the plasma membrane. This selectively permeable barrier is composed of a phospholipid bilayer with embedded proteins, which regulates the movement of substances in and out of the cell. This structure helps maintain the internal environment of the cell, allowing it to sustain essential biochemical processes.
What is an open system in physics and how does it differ from closed and isolated systems?
An open system in physics is one that can exchange both energy and matter with its surroundings. This is in contrast to closed systems, which can only exchange energy, and isolated systems, which cannot exchange either energy or matter with their surroundings.
Does an isolated system allow matter and energy to enter or exit?
An air conditioning system an OPEN system
How would you use the words isolated system in a sentence?
An isolated system cannot exchange either energy or matter outside the boundaries of the system
What type of system allows energy but no matter to enter and exit?
An isolated system allows energy to enter and exit, but no matter can pass in or out. This means that while the system can exchange energy with its surroundings, it remains closed off to any physical substances.
Is Mesopotamia isolated?
The Mesopotamia was not an isolated country. The fertile valley created a flourished civilization, opening the country to exchange goods and ideas from other parts of the world.
What is the best example of an isolated system?
The best example of an isolated system is the universe itself. It is considered isolated because it does not exchange matter or energy with anything outside of it. This means that no external forces can affect its internal workings.
How can you have temperature without heat?
Temperature is a measure of the average kinetic energy of the particles in a substance, while heat is the transfer of energy between substances due to a temperature difference. It is possible to have a substance at a certain temperature without any transfer of heat occurring, for example, when the substance is thermally isolated or in thermal equilibrium.
