Is density directly proportional to pressure? Density is directly proportional to pressure and indirectly proportional to temperature. As pressure increases, with temperature constant, density increases. What does pressure equal to? Pressure (p) is defined as the normal force F per unit area A over which the force is applied, or. p=FA. p = F A […]
What is the main form of energy?
What is the main form of energy? After hundreds of years of observation and experimentation, science has classified energy into two main forms: kinetic energy and potential energy. In addition, potential energy takes several forms of its own. Kinetic energy is defined as the energy of a moving object. What is energy transferred from? Energy […]
Is Iron bad for copper pipes?
Is Iron bad for copper pipes? On cold-water piping, pitting and corrosion is often caused by an excess amount of flux residue. Iron deposits from a rusty water heater can also corrode copper pipes. What pH level is toxic? Toxic effects on survival, motility, and growth decreased with increasing pH. From pH 6.9 to 9.0, […]
What are the three components of sound?
What are the three components of sound? It is received wisdom within the sonic branding business, that there are three different types, or elements, of sound. These are voice, ambience (or effects) and music. What are the basic components of sound? The basic components of a sound wave are frequency, wavelength and amplitude. What are […]
What are the three layers of soil profile?
What are the three layers of soil profile? The main layers of the soil are topsoil, subsoil and the parent rock. Each layer has its own characteristics. These features of the layer of soil play a very important role in determining the use of the soil. Soil that has developed three layers, is mature soil. […]
What happens when two pure substances are mixed?
What happens when two pure substances are mixed? If we take two or more pure substances and mix them together, we refer to this as a mixture. Mixtures can always be separated again into component pure substances, because bonding among the atoms of the constituent substances does not occur in a mixture. What most commonly […]
Does the melting point increase across a period?
Does the melting point increase across a period? Melting and boiling points increase across the three metals because of the increasing strength of their metallic bonds. The number of electrons which each atom can contribute to the delocalized “sea of electrons” increases. The atoms also get smaller and have more protons as you go from […]
What is the major difference between simmering and poaching?
What is the major difference between simmering and poaching? Poaching is a technique typically used for delicate foods including eggs, fish and fruits. In order to poach food effectively, it must be completely submerged in water. Simmering requires the temperature of the liquid to be between 185 to 200 degrees. What food can be boiled? […]
Where do magnetic fields come from?
Where do magnetic fields come from? The magnetic field is generated by electric currents due to the motion of convection currents of a mixture of molten iron and nickel in the Earth’s outer core: these convection currents are caused by heat escaping from the core, a natural process called a geodynamo. How is Earth’s magnetic […]
Which wire has more resistance thick or thin?
Which wire has more resistance thick or thin? The resistance of a thin wire is greater than the resistance of a thick wire because a thin wire has fewer electrons to carry the current. The relationship between resistance and the area of the cross section of a wire is inversely proportional . Which wire produce […]
