In a COSHH (Control of Substances Hazardous to Health) file, you would expect to find information on hazardous substances used in the workplace, such as chemicals, solvents, and cleaning products. This would include details on their potential health effects, safe handling procedures, and emergency response protocols.
an insulator
Two different samples of a pure substance would have the same physical properties, such as color, melting point, boiling point, and density. Their chemical properties, like reactivity and ability to form specific compounds, would also be identical. Variations in the samples' properties could indicate impurities present.
Proprioception
The substance with a larger molecular mass will generally have larger dispersion forces. Additionally, molecules with more surface area tend to have stronger dispersion forces.
A substance with low specific heat capacity and low thermal conductivity would heat up most quickly because it requires less energy to raise its temperature and does not distribute heat effectively. Materials like metals and low-density liquids generally heat up quickly compared to dense solids with high specific heat capacities.
an insulator
The student would expect to find carbon dioxide in the test tube, as it is a product of cellular respiration.
blood in the renal vein
If the two models were compared in a diffusion test, you would expect to see differences in how well they diffuse a substance. The model with higher diffusion capabilities would show a faster and wider spread of the substance compared to the model with lower diffusion capabilities.
alcohol, a by product of the fermentation
Mucus is a substance commonly expelled from the compound alveolar gland. It helps to trap foreign particles and bacteria, enabling the body to remove them from the respiratory system.
COSHH, in any employment in the UK, means 'Control of Substances Harmful to Health'. So you would have to have systems and procedures in place so that neither you nor your customer could swallow the hairdressing oils, sprays, colourings etc. Sorry, I don't know what the 'dpes' means.

no we cannot everything changes with time even a pure substance looses it's some of the properties after some time so the color also changes .
Another asterisk with added information.
In a database, you would expect to find organized and structured information such as financial transactions, customer details, inventory records, employee data, product information, and more. Databases are designed to store large volumes of data efficiently and allow for easy retrieval and manipulation of that data.
