What happens during eversion? Inversion involves the movement of the sole towards the median plane – so that the sole faces in a medial direction. Eversion involves the movement of the sole away from the median plane – so that the sole faces in a lateral direction. What causes eversion? When rotation is imparted to […]

What is a good U value for insulation? The best insulating materials have a U-value of close to zero – the lower the better. Building regulations currently stipulate that for a new building, the elements must have maximum U-values as follows: Wall – 0.3 W/m2k. Roof – 0.15 W/m2k. What is the most energy efficient […]

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 […]

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 […]

What do frogs do to protect themselves? The frog has enemies that will eat them. The skin will secret and cover the body with the poison and this will deter the enemy from eating them.
