What happens when you burn sodium chloride?
What happens when you burn sodium chloride? A typical flame will burn yellow-orange with a little bit of blue near the base of the wick. When you burned the skewer tip coated with sodium chloride, you should have seen that the flame was pure yellow-orange (without any blue). This is because when the metal sodium […]
Are kinematic equations valid when acceleration is zero?
Are kinematic equations valid when acceleration is zero? The equations can be utilized for any motion that can be described as being either a constant velocity motion (an acceleration of 0 m/s/s) or a constant acceleration motion. They can never be used over any time period during which the acceleration is changing. Each of the […]
What is rule of inheritance?
What is rule of inheritance? Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Offspring therefore inherit one genetic allele from each parent when sex cells unite in fertilization. … What are the […]
Which metal expands the most when heated?
Which metal expands the most when heated? potassium metal Does heat shrink or expand metal? What does heat do to metal? The expansion (or contraction) of any material is due to the kinetic energy of its atoms. When a material is heated, the increase in energy causes the atoms and molecules to move more and […]
Which country time zone is first?

Which direction does the jet stream flow?
Which direction does the jet stream flow? Jet streams are relatively narrow bands of strong wind in the upper levels of the atmosphere. The winds blow from west to east in jet streams but the flow often shifts to the north and south. Jet streams follow the boundaries between hot and cold air. How far […]
