Hey!!
here is your answer >>>
In order to find out which metal gains heat faster, we will have to find out their specific heat!. Specific heat is the heat required to raise the temperature of the unit substance, The specific heat of gold and brass are 0.126 for gold and 0.380 for brass!. The specific heat of gold is less than brass!. So, gold will gain heat faster!.
Hope my answer helps!
Since it was specifically stated that heat is released, therefore
heat is located on the right side of the reaction equation. Also stating the
states of each compound, the complete balanced reaction would be:
C2H5OH (l) + 3 02 (g) -----> 2 CO2 (g) + 3 H2O (g) + 1235
kJ

Does the Big Bang theory count?
<span>The slim exit of the
column is first persisted with glass wool or a permeable plate in order to sustain
the column packing element and keep it from getting out of the tube. Then the
adsorbent solid, which is usually a silica, is firmly packed into the glass
tube to make the separating column. The packing of the non-moving phase into
the glass column must be done with precaution to create an even distribution of
material. An even distribution of adsorbent material is very important to lessen
the existence of air bubbles and/or channels inside the column. To finish
preparing the column, the solvent to be used as the mobile phase is delivered
through the dry column. Then the column is said to be "wetted" and
the column must stay wet throughout the entire procedure. Once the column is properly
prepared, the sample to be separated is placed at the top of the wet column.</span>
Herbivores, which eat autotrophs, are the second trophic level. Carnivores, organisms that consume animals, and omnivores, organisms that consume both plants and animals, are the third trophic level. Autotrophs are called producers, because they produce their own food.
