What is true fluid pressure? The pressure in a fluid at any given depth is constant, and it is exerted equally in all directions. What is fluid pressure and its properties? There are two factors that affect fluid pressure. These two factors are the depth of the fluid and its density. Depth of the fluid: […]

Does water have a fixed volume?
Does water have a fixed volume? Changes of State: Solids, Liquids, and Gases Just like any substance, water can exist in three different forms, called states: solid, liquid and gas. As a liquid, a substance has a fixed volume, but its shape changes to fill the shape of its container. For instance, a glass of […]
How do you express uncertainty in measurements?
How do you express uncertainty in measurements? Uncertainties are almost always quoted to one significant digit (example: ±0.05 s). If the uncertainty starts with a one, some scientists quote the uncertainty to two significant digits (example: ±0.0012 kg). Always round the experimental measurement or result to the same decimal place as the uncertainty. What is […]
How does an internal combustion engine work simple?
How does an internal combustion engine work simple? The engine consists of a fixed cylinder and a moving piston. After the piston compresses the fuel-air mixture, the spark ignites it, causing combustion. The expansion of the combustion gases pushes the piston during the power stroke. In a diesel engine, only air is inducted into the […]

What are the 5 major types of biological macromolecules?
What are the 5 major types of biological macromolecules? There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids), and each is an important component of the cell and performs a wide array of functions. What are 4 macromolecules and their monomers? Monomers are the building blocks of the four basic […]
Do ionic bonds share electrons?
Do ionic bonds share electrons? The two most basic types of bonds are characterized as either ionic or covalent. In ionic bonding, atoms transfer electrons to each other. In contrast, atoms with the same electronegativity share electrons in covalent bonds, because neither atom preferentially attracts or repels the shared electrons. Do ionic bonds have low […]
Why is water important in the carbon cycle?
Why is water important in the carbon cycle? Water provides the ingredients needed for plants to do photosynthesis and remove carbon dioxide. The oceans are another important carbon sink. Oceans take in carbon dioxide, which is either dissolved or incorporated into sea plants or animals. Is the carbon cycle a positive feedback loop? Complex systems […]
What are the 3 parts of the hindbrain?
What are the 3 parts of the hindbrain? There are three main parts of the hindbrain – pons, cerebellum, and medulla oblongata. Most of the 12 cranial nerves are found in the hindbrain.
