FAQs on Science Words That Start With V
Here are some frequently asked questions about science words starting with “V”:
What is the difference between speed and velocity?
Speed is a scalar quantity that measures how fast an object is moving, while velocity is a vector quantity that measures both the speed and direction of an object’s motion. For example, a car traveling at 60 mph has a speed of 60 mph, but its velocity also includes the direction it’s traveling, such as 60 mph north.
How does a vaccine work?
A vaccine works by introducing a weakened or inactive form of a pathogen (virus or bacteria) into the body. This stimulates the immune system to produce antibodies that recognize and fight the pathogen. If the person is later exposed to the actual pathogen, their immune system will be prepared to quickly mount a defense and prevent illness.
What factors affect the viscosity of a fluid?
The viscosity of a fluid is affected by several factors, including temperature, pressure, and the type of molecules that make up the fluid. Generally, viscosity decreases with increasing temperature and increases with increasing pressure. Fluids with larger or more complex molecules tend to have higher viscosities.
What causes volcanic eruptions?
Volcanic eruptions are caused by the buildup of pressure from magma (molten rock) beneath the Earth’s surface. This pressure forces the magma to rise through vents and fissures in the Earth’s crust. The eruption can be explosive, releasing ash, gas, and lava, or effusive, with lava flowing steadily onto the surface.
Why are valence electrons important?
Valence electrons are the electrons in the outermost energy level of an atom. They are important because they determine how an atom will interact with other atoms to form chemical bonds. The number of valence electrons an atom has dictates its chemical properties and how it will combine with other elements.
What is the role of vacuoles in cells?
Vacuoles are membrane-bound organelles found in plant, fungal, and some animal cells. They serve various functions, including storing water, nutrients, and waste products. In plant cells, the central vacuole helps maintain turgor pressure, which is essential for cell rigidity and plant structure.
What is a vector in physics?
In physics, a vector is a quantity that has both magnitude (size) and direction. Examples of vector quantities include force, velocity, acceleration, and displacement. Vectors are often represented graphically as arrows, with the length of the arrow indicating the magnitude and the direction of the arrow indicating the direction of the vector.
What are the major types of volcanoes?
The major types of volcanoes include shield volcanoes, composite volcanoes (stratovolcanoes), and
cinder cone volcanoes. Shield volcanoes are broad, gently sloping volcanoes formed by the eruption of fluid basaltic lava. Composite volcanoes are steep-sided volcanoes composed of alternating layers of lava and ash. Cinder cone volcanoes are small, cone-shaped volcanoes formed by the accumulation of cinders and other volcanic debris.
How do viruses replicate?
Viruses replicate by invading a host cell and using the host cell’s machinery to produce more virus particles. The virus attaches to the host cell, injects its genetic material (DNA or RNA) into the cell, and then hijacks the cell’s ribosomes and other organelles to synthesize viral proteins and replicate the viral genome. The new virus particles are then assembled and released from the host cell, often destroying the host cell in the process.
What is the Van der Waals force?
Van der Waals forces are weak, short-range attractive forces between atoms and molecules. These forces arise from temporary fluctuations in the distribution of electrons, which create transient dipoles. Van der Waals forces are important in many physical and chemical phenomena, including the condensation of gases, the adhesion of surfaces, and the structure of biological molecules.
