Why is a burette more accurate? Burettes are larger than a pipette, it has a stopcock at the bottom to control the release of liquid. Burette is similar like graduated cylinder and is easier to measure a required volume of liquid through graduations. But, it has large meniscus and hence its accuracy and precision is […]
What are the rules for a series circuit?
What are the rules for a series circuit? In summary, a series circuit is defined as having only one path through which current can flow. From this definition, three rules of series circuits follow: all components share the same current; resistances add to equal a larger, total resistance; and voltage drops add to equal a […]
How many different types of batteries are there?
How many different types of batteries are there? three types What is the main function of a battery? 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. The […]
How long must you boil water to make it safe to drink?
How long must you boil water to make it safe to drink? Boil water, if you do not have bottled water. Boiling is sufficient to kill pathogenic bacteria, viruses and protozoa (WHO, 2015). If water is cloudy, let it settle and filter it through a clean cloth, paperboiling water towel, or coffee filter. Bring water […]
What temperature does water boil at 100 psi?
What temperature does water boil at 100 psi? Absolute pressure Water boiling point [bara] [1×105*Pa] [psia] [°F] 6.619 96.0 325 6.757 98.0 326 6.895 100 328 Does water boil at higher pressure? A liquid at high pressure has a higher boiling point than when that liquid is at atmospheric pressure. For example, water boils at […]
Why do black things absorb light?
Why do black things absorb light? Light energy can be converted into heat energy. A black object absorbs all wavelengths of light and converts them into heat, so the object gets warm. A white object reflects all wavelengths of light, so the light is not converted into heat and the temperature of the object does […]
What is the correct pathway for vision?
What is the correct pathway for vision? The visual pathway consists of the retina, optic nerves, optic chiasm, optic tracts, lateral geniculate bodies, optic radiations, and visual cortex. The pathway is, effectively, part of the central nervous system because the retinae have their embryological origins in extensions of the diencephalon. Which controls the amount of […]
Which gun has the most recoil?
Which gun has the most recoil? 950 JDJ. This gun is no joke. It uses 240 grains of powder to push a 2,400-grain bullet 2,100 fps. It bites on both ends though, generating 277 foot-pounds of recoil, or approximately 10 times as much as a 30-06. What rifle kicks the hardest? Petzal: The Hardest Kicking […]
Why the adsorption is always exothermic?
Why the adsorption is always exothermic? The particles are attached to the surface of another medium for the reaction to take place. During this process the residual forces on the surface of adsorbent decreases which in turn decreases the surface energy. This energy appears in the form of heat, hence adsorption is exothermic in nature. […]
How do you survive freezing temperature without heat?
How do you survive freezing temperature without heat? Here are a few tips to stay warm and happy this winter with no heat: Reduce as much heat loss as possible. Put blankets over all the windows and outside doors, and bean bag draft busters at the base of every door. Adding Insulation Supercharges Your Walls. […]
