What kind of mixtures can be separated by distillation? Fractional distillation is a method for separating a liquid from a mixture of two or more liquids. For example, liquid ethanol can be separated from a mixture of ethanol and water by fractional distillation. This method works because the liquids in the mixture have different boiling […]
How is data sent through wires?
How is data sent through wires? Originally Answered: How data is transmitted through wires in the computer ? Most simply, by pulses of electricity. This is a crude analogy, but think of a light switch. You flip it on, and it sends electricity down the wire to the light. Which system uses digital transmission? Which […]
What are 3 examples of physical weathering?
What are 3 examples of physical weathering? Some examples of physical weathering mechanisms: Frost wedging. Frost wedging happens when water filling a crack freezes and expands (as it freezes, water expands 8 to 11% in volume over liquid water). Heat/Cold Cycles. Unloading. What are 4 types of physical weathering? Four Types of Physical Weathering Weathering […]
What is the relation between surface tension and surface energy?
What is the relation between surface tension and surface energy? The attractive force of the molecules present at the surface of a liquid towards each other is called the surface tension of that liquid. Surface energy is the equivalent attractive force present between the molecules at the surface of a solid substance. What are the […]
What are the different columns called?
What are the different columns called? In the periodic table of elements, there are seven horizontal rows of elements called periods. The vertical columns of elements are called groups, or families. What three families are found in the center of the periodic table? The three families that are found in the center portion of the […]
Is a primary wave transverse?
Is a primary wave transverse? When seismic waves are first created, they travel outwards in all direction from their source. Body waves travel through the interior of the earth, and have two main types: P-Waves (Primary waves) are Longitudinal Waves. S-Waves (Secondary waves) are Transverse Waves. Do P or S waves cause more damage? S […]
Does positive and negative matter with lights?
Can velocity be zero if acceleration is zero?
Can velocity be zero if acceleration is zero? When acceleration is zero then velocity of object can be zero or constant. The body continues to move with its velocity throughout. For e.g if a train is at rest then acceleration is zero and velocity remains zero. Why does velocity change direction zero? The velocity, that […]
Where does the dark go when you turn on the light?
What is a heterogeneous mixture?
What is a heterogeneous mixture? A heterogeneous mixture is a mixture in which the composition is not uniform throughout the mixture. A heterogeneous mixture consists of two or more phases. When oil and water are combined, they do not mix evenly, but instead form two separate layers. Each of the layers is called a phase. […]
