chemical energy. A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit. What type … Continue reading →

A disadvantage is that if you are repeatedly exposed to this toxic element, it can cause anemia, brain damage and high blood pressure. An advantage is that lead has a low melting point, so it is easy to shape and … Continue reading →

After decades of international pressure by a UN group, leaded gasoline is no longer being produced. The last leaded fuel has finally disappeared from gas stations. The last country in the world to sell it: Algeria. Can you buy leaded … Continue reading →

Covalent compounds (solid, liquid, solution) do not conduct electricity. Metal elements and carbon (graphite) are conductors of electricity but non-metal elements are insulators of electricity. Which substance does not conduct electricity in any state? NaCl is not a conductor of … Continue reading →

If you have to define the meaning of electrical conductors in the simplest way, they are materials that allow electricity to flow through them easily. If we compare two types of material and the first one allows better flow of … Continue reading →

Melting and boiling points: Ionic compounds tend to have higher melting and boiling points than covalent compounds. Mechanical properties: Ionic compounds tend to be hard and brittle while covalent compounds tend to be softer and more flexible. Are molecular compounds … Continue reading →

Semtex is a general-purpose plastic explosive containing RDX and PETN. It is used in commercial blasting, demolition, and in certain military applications. What is Semtex and how does it work? Explosives such as Semtex, C4 or P4 detonate in a … Continue reading →

26.2 mm. A C battery measures 50 mm (1.97 in) length and 26.2 mm (1.03 in) diameter. The voltage and capacity of a C-size battery depends on the battery chemistry and discharge conditions. The nominal voltage is 1.5V. What is … Continue reading →

Look at the top of the battery. Liquid lead acid batteries have caps or removable tops unless they say “sealed” on the label. Gel-filled and AGM lead acid batteries have flat tops except for the positive and negative terminals. How … Continue reading →

The inverter with the size of 1000 watts will lack the energy supply. As a result, the microwave will stop working. When you start the microwave, it will use 700 watts, but as you start cooking or heating, the microwave … Continue reading →

Gasoline converts chemical energy to mechanical energy in cars. Steam engines convert thermal energy into mechanical energy in a train. Your body converts chemical energy from nutrients to mechanical energy for movement. What converts chemical energy to mechanical? In a … Continue reading →

Button batteries (or cells) do not contain lithium but for instance alkaline and have a 1,5 Volt output. They are generally a bit smaller than coin batteries, for instance the popular LR44 alkaline battery is 11,6*5,4 mm. Is coin battery … Continue reading →

Panasonic AAA Alkaline Batteries last longer than ordinary zinc-carbon batteries. Alkaline AAA battery is equipped with Anti-Leak protection. This protects devices from damage due to battery rupture and leakage. Alkaline batteries are designed to protect power for up to 10 … Continue reading →

The Technical Answer: Yes It’s possible to use a marine battery in place of electric golf cart batteries. They’re both technically gel lead acid batteries designed for deep-cycle purposes, reports It Still Runs. How long will marine batteries last in … Continue reading →

The applications of nanotechnology, commonly incorporate industrial, medicinal, and energy uses. These include more durable construction materials, therapeutic drug delivery, and higher density hydrogen fuel cells that are environmentally friendly. What are three examples of nanotechnology? A few examples of … Continue reading →
