What are 5 physical changes that can occur to a substance?
Melting: The substance changes from a solid to a liquid as heat is applied. Freezing: The substance changes from a liquid to a solid as it loses heat. Evaporation: The substance changes from a liquid to a gas as it is heated. Condensation: The substance changes from a gas to a liquid as it cools. Sublimation: The substance changes directly from a solid to a gas without going through a liquid phase.
If the air temperature dropped by 5 degrees would you feel it?
Yes, a change of 5 degrees in air temperature would likely be noticeable and you may feel the difference, especially if it happens relatively quickly. Our skin is sensitive to temperature changes, so a drop of 5 degrees could be felt as a change in comfort level or even trigger physical responses like shivering.
What are the 5 physical properties of matter?
The five physical properties of matter are color, odor, density, melting point, and boiling point. These properties can be observed or measured without changing the chemical composition of the substance.
What is the maximum acceleration in gs that a human body can withstand before experiencing physical discomfort?
The maximum acceleration in gs that a human body can withstand before experiencing physical discomfort is typically around 5 gs.
5 processes that are physical changes?
Boiling water: Water changing from a liquid to a gas. Melting ice: Ice changing from a solid to a liquid. Dissolving sugar in water: Sugar particles evenly dispersing in water. Cutting a piece of paper: Paper being physically separated into smaller pieces. Crushing a can: Can being flattened without changing its chemical composition.
