How do you solve for change in velocity? Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt. Speed (or rate, r) is a scalar quantity that measures the distance traveled (d) over the change in time (Δt), […]
Does sugar dissolve faster in hot or cold water?
Does sugar dissolve faster in hot or cold water? Sugar dissolves faster in hot water than it does in cold water because hot water has more energy than cold water. When water is heated, the molecules gain energy and, thus, move faster. As they move faster, they come into contact with the sugar more often, […]

How do you ensure accuracy in a titration?
How do you ensure accuracy in a titration? Terms in this set (9) Meniscus at eye level. To avoid parallax error. White tile. To see end point clearer. Remove funnel before titrating. Increases the vol making the titre smaller. Dropwise addition. No bubbles in pipette & burette at the tip. Swirling during titration. Few drops […]
What are the 3 common units of volume?
What are the 3 common units of volume? Three common units of volume are: cubic centimeters. liters. gallons. What are examples of units of volume? Volume measures capacity. For example, the volume of a bowl is the amount of space inside the bowl or how much water, for example it would take to fill the […]
How do we use convex mirrors?
How do we use convex mirrors? These convex mirrors are used for cars because they give an upright image and provide a wider field of view as they are curved outwards. Convex mirrors are also often found in the hallway of various buildings including hospitals, hotels, schools, stores and apartment building. Where do we use […]
What are the three types of sedimentary rocks?
What are the three types of sedimentary rocks? There are three different types of sedimentary rocks: clastic, organic (biological), and chemical. Clastic sedimentary rocks, like sandstone, form from clasts, or pieces of other rock. What is the most common sedimentary rock? 95% of all sedimentary rocks consists of sandstones (made up of sand sized fragments), […]

What are 3 ways natural selection can change a distribution of traits?
What are 3 ways natural selection can change a distribution of traits? Natural selection on single-gene traits can lead to changes in allele frequencies and, thus, to changes in phenotype frequencies. Natural selection on polygenic traits can affect the distributions of phenotypes in three ways: directional selection, stabilizing selection, or disruptive selection. What is the […]
