Which choice best describes the specific heat of water compared with that of metals? a)the specific heat of water is less than the specific heat of metals. b)the specific heat of water is about the same as the specific heat of metals. c)the specific heat of water is greater than the specific heat of metals. d)the specific heat cannot be measured for water.

C. The specific heat of water is greater than the specific heat of metals.

The specific heat is defined as the amount required to raise the temperature of a unit mass of a substance by 1 degree Celsius.

This is expressed mathematically as

Q= mc∆T

Where Q is the energy/heat required which is measured in Joules.

m is the mass (grams)

c is the specific heat which is measured in joule/gram degree Celsius.

∆T- change in temperature

Substance which has a high specific heat require a lot of heat for its temperature to be raised by one degree. On the other hand substances with lower specific heat require only little amount of heat for its temperature to be raised by one degree.

Consider an equal mass of metal and water. If both are heated at the same time,the metal would become hotter than the water much faster. This is because the specific heat of the metal is lower than the water. Hence it requires only a little heat for its temperature to raised by one degree.

Thus we can conclude that the specific heat of water is much greater than that of a metal.

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
