What is the impact of age on flexibility quizlet? What is the impact of age on flexibility? Younger people tend to be more […]

What is the coldest liquid on Earth? Liquid helium Is liquid nitrogen or liquid oxygen colder? Liquid nitrogen has a lower boiling point at −196 °C (77 K) than oxygen’s −183 °C (90 K), and vessels containing liquid nitrogen can condense oxygen from air: when most of the nitrogen has evaporated from such a vessel, […]

Why the nucleus is the most important? The most important function of the nucleus is to store the cell’s genetic information in the form of DNA. DNA holds the instructions for how the cell should work. Which cell part is most important? The nucleus is the most important part of a cell. It is the […]

Which compound would have a stronger ionic bond? Alf3 Why do some ionic compounds have low melting points? The melting and boiling points of molecular compounds are generally quite low compared to those of ionic compounds. This is because the energy required to disrupt the intermolecular forces between molecules is far less than the energy […]

Why does the ray of light passing through the optical Centre of a lens not get any deviation? The ray passing through optical center does no deviate because the curvature of the Lens at the incident and exit point are exactly opposite so the deviation at the first point is cancelled at the other point. […]

Is known as the way light reflects off a mineral? Luster describes the reflection of light off a mineral’s surface. Mineralogists have special terms to describe luster. One simple way to classify luster is based on whether the mineral is metallic or non-metallic. How can you identify a minerals color? You can identify a mineral […]
