What happens to the temperature of naphthalene during melting?
Lab: Melting / Freezing Point of NaphthaleneObjective: In this lab, you will investigate the melting and freezing point of the substance, naphthalene (moth ball flakes). You will heat solid naphthalene and record temperature changes and examine the graph to determine the melting point of the substance. You will then cool naphthalene and record temperature changes in order to determine the Freezing point of the substance Part A: What happens to temperature as naphthalene melts?Objective: As heat is applied to liquid naphthalene, the temperature rises. As the temperature rises, the naphthalene will eventually start to melt. This lab experiment tries to answer the question: what happens to the temperature of naphthalene as it melts? In this lab, you will heat the liquid naphthalene, and record the temperature changes. You will graph the temperature changes before drawing any conclusions.Part B: Determining the freezing point of naphthaleneObjective: Freezing point is a characteristic property of matter. As heat is taken away from a liquid, the temperature of that liquid decreases as the substance begins to freeze. This lab experiment tries to answer the question: what is the freezing point of an unknown liquid (naphthalene)? In this lab, you will cool liquid naphthalene, and record the temperature changes. You will graph the temperature changes before drawing any conclusions.
When two objects of different masses are dropped simultaneously from the top of a tower If air resistance is same on them which object touches the ground first and why?
The sphere with more mass will reach the ground first because it has more inertia and it's speed and acceleration are less affected by the resistance caused by the air (it also has a higher terminal velocity). If dropped in a vacuum, however, they would both accelerate at the same speed and hit the ground simultaneously.
How does the invention of silk work?
Silk is not do much an invention as a discovery. ?The discovery that the cocoon of the silkworm moth lava could be boiled and unravelled as one continuous thread. This thread is then twinned with others to make a silk yarn which is woven into fabric. The secret of silk was discovered by the ancient Chinese who learned how to domesticate and farm the silk worm moths, feeding them on a type of mulberry leaf.
Why does garage door go down and bounce back up?
With an electric garage door opener/closer, there are systems to prevent the door from closing on a child who might be in the way. If the infrared sensor across the door is blocked by a leaf or any other object, the door will close and open immediately, or not close at all. If there is a rock or other object that is pushing against the door as it tries to finish closing, the door will immediately open. Sometimes a moth may construct a cocoon in the sensor, blocking the IR and producing similar results.
What does white wave mean?
I was wondering what my name meant (Jenny) so I did some research and it is Welsh for white wave. (No my name is not Jennifer it's just Jenny) Same! I've suddenly just got into symbols, dreams, etc (no I'm not crazy) and I know my name (Jenny) means white wave. I googled it, and all it came up with was some spas and a outdoor clothes company. All I know is there is a moth called white wave and a white wave (you know when waves go all spray-y and white (I can't find a better adjective)). !
