Sample Problem

A) Calculate the surface area. surface area of cube = number of faces × area of one face surface area of cube = 6(2 cm × 2 cm) surface area of cube = 24 cm 2

B) Calculate the volume. volume of cube = side × side × side volume of cube = 2 cm × 2 cm × 2 cm volume of cube = 8 cm 3

C) Calculate the surface area-to-volume ratio. A ratio is a comparison between numbers. It can be written by placing a colon between the numbers being compared.surface area : volume = 24 cm 2: 8 cm 3surface area : volume = 3 cm 2: 1 cm 3

Can someone please explain to me how particles in a solid can vibrate back and forth? I'll give brainliest!!! Big Time... This is a physical science question, but I am just putting it as a biology question because physical science is not an option...

Answers


The particles are held together too tightly to allow too much movement but the particles do vibrate in their positions. With an increase in temperature, the particles gain kinetic energy and vibrate faster and more strongly.
Solids particles are packed closely together. The particles are only able to vibrate about fixed positions; they can’t move around because they have strong force of attraction between them, which keep them together. Heat is usually the reason why solids vibrate. When you heat a solid the energy provided by the heat source makes the solid vibrate faster and faster. It vibrates so fast that it causes the force of attraction in between the particles become no longer strong enough to hold them together, and here the solid becomes a liquid.
