What is the 5 step design process? The five stages of Design Thinking, according to d. school, are as follows: Empathise, Define (the problem), Ideate, Prototype, and Test. Let’s take a closer look at the five different stages of Design Thinking. What is the difference between scientific investigation and technological design? Scientific inquiry is used […]

Why light shines off of a mirror? A mirror is a surface that reflects light more perfectly than ordinary objects. Most objects reflect light at varying angles. This is more accurately called refraction, because the rays of light bend when they hit the object and move off in varying directions. This allows us to see […]

Is Bedrock Real? Bedrock is the hard, solid rock beneath surface materials such as soil and gravel. Bedrock can extend hundreds of meters below the surface of the Earth, toward the base of Earth’s crust. The upper boundary of bedrock is called its rockhead. Above the rockhead, bedrock may be overlain with saprolite. Is Bedrock […]

What is the relationship between the earth and the moon? The Moon is smaller than the Earth and orbits around the Earth in 27.3 days as the Earth revolves around the Sun. The Moon is held in orbit around the Earth by the force of gravity. In turn the Earth and all the other planets […]

What causes hydrogen gas to glow when an electric current is passed through it? Terms in this set (62) What gives gas-filled lights their colors? An electric current passing through the gas in each glass tube makes the gas glow with its own characteristic color. These electrons lose energy by emitting light when they return […]

What is the smallest unbreakable unit of a compound? molecule What are the similarities and differences of the two compounds? A compound contains atoms of different elements chemically combined together in a fixed ratio. An element is a pure chemical substance made of same type of atom. Compounds contain different elements in a fixed ratio […]

How do I increase the resolution of my GC? To improve the resolution of earlier eluting peaks, decrease the initial temperature or increase the initial hold time. Decreasing the initial temperature usually results in the largest resolution improvement, but analysis times are substantially increased (Figure 32a). What affects resolution in GC? Changes in resolution are […]
