What is the main purpose of recycling? Recycling helps protect the environment Recycling reduces the need for extracting (mining, quarrying and logging), refining and processing raw materials all of which create substantial air and water pollution. As recycling saves energy it also reduces greenhouse gas emissions, which helps to tackle climate change. What are the […]
Why is a calorimeter a good insulator?
Why is a calorimeter a good insulator? A calorimeter uses an insulated lid, or insulated surroundings. The goal of insulating the bomb calorimeter system is to minimize the temperature loss from the system (calorimeter) to the surroundings (air) over time. Does Styrofoam cup absorb heat? A styrofoam cup makes for a good adiabatic wall and […]

Why do Thrust faults occur?
Why do Thrust faults occur? Reverse dip-slip faults result from horizontal compressional forces caused by a shortening, or contraction, of Earth’s crust. The hanging wall moves up and over the footwall. Thrust faults are reverse faults that dip less than 45°. How are normal faults formed? Normal Faults: This is the most common type of […]
Why is elasticity better than slope?
Why is elasticity better than slope? The reason is that slope and elasticity are different concepts. Slope measures the steepness or flatness of a line in terms of the measurement units for price and quantity. Elasticity measures the relative response of quantity to changes in price. How do you calculate the elasticity of a slope? […]
What is the closest star?
What is the closest star? Proxima Centauri How do stars die? Stars die because they exhaust their nuclear fuel. Once there is no fuel left, the star collapses and the outer layers explode as a ‘supernova’. What’s left over after a supernova explosion is a ‘neutron star’ – the collapsed core of the star – […]
Is Amu bigger than grams?
Is Amu bigger than grams? Since a carbon atom weighs 12 AMU, one AMU is equivalent to 1.66 x 10-24 grams. Conversely, one gram is equivalent to 6.022 x 1023 AMU, which is Avogadro’s number. Are all metals Monatomic? Metals form extended “moleucules”, a vast network of atoms, (like diamond, for instance) in which each […]
Why is correlation not good?
Why is correlation not good? The stronger the correlation, the more difficult it is to change one variable without changing another. It becomes difficult for the model to estimate the relationship between each independent variable and the dependent variable independently because the independent variables tend to change in unison. Which of the following is a […]
What color is most visible in low light?
What color is most visible in low light? yellow What Colour stands out at night? (And, of course, reflective stripes for nighttime visibility.) As mentioned above, fluorescent yellow-green is the best choice during the day—and best all-around choice for a single color. But as dusk sets in and lighting gets dim, orange-red and red start […]
