They are sometimes called inert gases. characteristics of matter that can be seen through direct observation such as density, melting point, and boiling point. Characteristics of matter that can only be observed when one substance changes into a different substance, such as iron into rust.
Answer:
See explanation
Explanation:
Freezing point and melting point increases slightly at higher altitude
The boiling point decreases at higher altitudes.
Air pressure decreases with altitude As a result of this, atmospheric pressure decreases and water must now boil at a lower temperature. In order to compensate for this lower boiling point of water, food must take a longer time to cook. The lowering of air pressure actually means that the air becomes thinner at higher altitudes.
Pressure cookers cook food at high pressure thereby reducing the cooking time significantly. This helps to retain 50% of the nutrients in the food, lower the kitchen temperature and lower the energy cost required to cook food.
Answer:
C. Aqueous Solutions
General Formulas and Concepts:
<u>Aqueous Solutions</u>'
- Dissociation
- Solvents and Solutions
Explanation:
Water is the universal solution that solvents are dissolved in. Whenever anything is dissolved in water, it will be an aqueous solution.
Strong ionic solutions dissolve into their ions when dissolved in water.
Weak acids and bases don't fully dissociate in water.
