It is a physical change. Any change in state or temperature is only physical unless it causes the atoms in the molecules to separate or rearrange themselves. In the case of freezing a biological sample, the point is to preserve it as it is, so the change would only be physical.
Yes, liquid nitrogen can be used for snap freezing biological samples. When samples are immersed in liquid nitrogen, the rapid freezing process helps to preserve the integrity of the cells by preventing the formation of ice crystals that can damage the cell structure.
The chemical that freezes stuff is called liquid nitrogen. It is used in various applications such as cryogenics, food preservation, and medical treatments. Liquid nitrogen is extremely cold, with a temperature of around -320F, making it ideal for freezing and preserving biological samples, food products, and even for creating special effects in the entertainment industry.
no. In some situations nitrogen is used to put out fires.

Liquid nitrogen is commonly used to achieve deep freezing temperatures. It has a boiling point of around -196°C and is used in various applications such as cryogenic storage and transportation of biological samples.
biological, chemical, or physical samples -Hope this could help y'all in some way!
you use them for heating things (added) mainly used fot heating solutions for chemistry
You think probable to chemical analysis of biological samples (blood, urine, etc.).
A microplate reader is a laboratory instrument which helps to detect chemical, physical or biological events samples in microtiter plates. These are most commonly used in research and drug discovery.
Physical- Something PURE. Chemical- Something that contains OTHER things.

Spectroscopy and microscopy can be combined to analyze biological samples by using spectroscopic techniques to identify the chemical composition of the sample and microscopy to visualize the structure and morphology of the sample at a microscopic level. This integration allows for a more comprehensive understanding of the biological sample, providing both chemical and structural information for a more detailed analysis.

Cryogenics freezing can lower temperatures to around -238 degrees Fahrenheit (-150 degrees Celsius) or even lower. These extremely low temperatures are necessary to preserve biological samples or materials for long-term storage.

- preparation of samples in analytical chemistry- all works in a chemical or biological laboratory- motor vehicles- preparation of drugs
Snap freezing is a rapid method of freezing biological samples to preserve cellular structures and biomolecules. It involves quickly freezing the sample at very low temperatures to prevent ice crystal formation, which can damage the cellular integrity. Snap freezing is commonly used in research and clinical settings to capture a snapshot of the sample's state at a specific moment in time.
