Which temperature scale is used in gas laws? Kelvin scale Why do gases fail to obey the general gas equation at high pressure and low temperature? Answer: At low temperatures and high pressure, the inter-molecular interactions of the gases become significant, as molecules are brought closer. Also, the volume of the gases takes a finite […]

How far can you shoot a speargun? ‘Depends on how/where the shooting line is attached to the spear and how many “wraps” it can handle of shooting line around the line release mechanism. + ~1m of shooting line to where it attaches to the line anchor on the bottom of the muzzle (usually through a […]

What pressure should my bike Tyres be? 80 to 130 psi What is the air pressure for a 29 inch bike tire? For a 29 inch tire, the critical range is likely between 18 and 28 psi, depending upon your weight, your skills and the terrain. For Plus tires, that range is around 11 to […]

What is the formula of heat in electricity? Hence the heating effect produced by an electric current, I through a conductor of resistance, R for a time, t is given by H = I2Rt. This equation is called the Joule’s equation of electrical heating. Which instrument is used for measuring high temperatures? pyrometers What makes […]

How can a source be primary and secondary? A primary source gives you direct access to the subject of your research. Secondary sources provide second-hand information and commentary from other researchers. Examples include journal articles, reviews, and academic books. A secondary source describes, interprets, or synthesizes primary sources. Which is the best example of a […]

Is osmosis active or passive and why? Explanation: osmosis is the process in which water molecules move from a region of higher water potential to a region of lower potential down a water potential gradient across a partially permeable membrane, so little energy is required to carry out this process, thus it is a form […]

What is the best Medicare Advantage plan for seniors? Best Companies for Medicare Advantage Plans: Best Overall: easyMedicare. Cheapest: Aetna Medicare Advantage. Best Coverage: Humana. Best for Special Needs: Cigna. Does Medicare pay 100 percent of hospital bills? You will also have to pay a deductible before Medicare benefits begin. Medicare will then pay 100% […]

What is called vaporization? Vaporization, conversion of a substance from the liquid or solid phase into the gaseous (vapour) phase. If conditions allow the formation of vapour bubbles within a liquid, the vaporization process is called boiling. Direct conversion from solid to vapour is called sublimation. What happens to particles after vaporization? Liquids evaporate faster […]

How do you push a car with a dead battery? Take the flathead or a key and — while pressing the brake pedal — push it down or over, depending on your vehicle. Don’t apply too much pressure. Check your owner’s manual to confirm which direction you should push if you feel excessive resistance. Can […]

What occurs first in an action potential? An action potential occurs when a neuron sends information down an axon, away from the cell body. Neuroscientists use other words, such as a “spike” or an “impulse” for the action potential. Action potentials are caused when different ions cross the neuron membrane. A stimulus first causes sodium […]
