Why is Aluminium ductile in terms of structure? The energy is transferred throughout the rest of the metal by the moving electrons. Metals are described as malleable (can be beaten into sheets) and ductile (can be pulled out into wires). This is because of the ability of the atoms to roll over each other into […]
What are 5 uses of neon?
What are 5 uses of neon? Neon is also used to make high-voltage indicators and switching gear, lightning arresters, diving equipment and lasers. Liquid neon is an important cryogenic refrigerant. It has over 40 times more refrigerating capacity per unit volume than liquid helium, and more than 3 times that of liquid hydrogen. What happens […]
What are causes of ocean acidification?
What are causes of ocean acidification? Ocean acidification is mainly caused by carbon dioxide gas in the atmosphere dissolving into the ocean. This leads to a lowering of the water’s pH, making the ocean more acidic. Many factors contribute to rising carbon dioxide levels. What happens during ocean acidification? When carbon dioxide (CO2) is absorbed […]
How electric and magnetic fields are produced?
How electric and magnetic fields are produced? Electric fields are produced by electric charges, and magnetic fields are produced by the flow of electrical current through wires or electrical devices. Because of this, low frequency EMR is found in close proximity to electrical sources such as power lines. What is the difference between electric fields […]
What do the rows mean on a periodic table?
What do the rows mean on a periodic table? Each row represents one period; the period number of an element indicates how many of its energy levels house electrons. Sodium, for instance, sits in the third period, which means a sodium atom typically has electrons in the first three energy levels. How do you identify […]
What is the name of the force exerted by the first object on a second object?
What is the name of the force exerted by the first object on a second object? exerted by two objects on each other are often called an action- reaction force pair. Either force can be considered the action force or the reaction force. You might think that because action-reaction forces are equal and opposite that […]
What is the formula for relative speed?
When balancing equations do you balance charges?
When balancing equations do you balance charges? Balance charge. Add e- (electrons) to one side of each half-reaction to balance charge. You may need to multiply the electrons by the two half-reactions to get the charge to balance out. It’s fine to change coefficients as long as you change them on both sides of the […]
What is process water?
What is process water? Process water is broadly defined as water used in industry, manufacturing processes, power generation and similar applications. . Is process water pure? Distilled water is produced by a process of distillation. Distillation involves boiling the water and then condensing the vapor into a clean container, leaving solid contaminants behind. Distillation produces […]
Can machine change the direction of force?
Can machine change the direction of force? Machines make work easier by increasing the amount of force that is applied, increasing the distance over which the force is applied, or changing the direction in which the force is applied. That’s because a machine doesn’t change the amount of work and work equals force times distance. […]
