Acertain material has a mass of 12.48 g while occupying 12.48 cm3 of space. what is this material?

The material is water as it has density of  

Explanation:

Density is defined as the mass contained per unit volume.  It is characteristic of a material.

Given : Mass of object =12.48 grams

Volume of the object =

Putting in the values we get:

Thus the density of the material is and material is water which has density of  .

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
