vitfil [10]

Explanation:

The temperature of the molten iron remained constant at 2750°C because of the heat absorbed to effect the phase change and not to change the temperature.

The heat of vaporization is a latent or hidden heat absorbed by substances that causes a phase change from liquid to gas.

  • In essence, the heat is used to break intermolecular bonds between the particles of the melted vat.
  • If enough heat is no supplied the molten vat will not boil off and become vapor.
  • In transitioning from liquid to gas, heat is absorbed by a body to effect the phase change.
  • When the body acquires enough heat, the particles are able to break off and boil.
  • At the 2750°C  mark, this is what is happening.

one bottle of aspirin holds 250 tablets, each containing 150 mg of aspirin and sells for $2.95. Another bottle holds 125 tablets
AlladinOne [14]
I bottle:

250 * 150mg = 37500mg

If 37500mg ------- cost ------- <span> $2.95
so 1mg       ------- cost ------- x

x = 1mg*</span> $2.95 / 37500mg =  $7,87*10⁻⁵ 

II bottle

125 * 200mg = 25000mg

If 25000mg ---------- cost ---------- <span>$3.50
so 1mg       ---------- cost ---------- x

x = 1mg* </span>$3.50 / 25000mg = $0,00014=$1,4*10⁻⁴


$7,87*10⁻⁵  < $1,4*10<span>⁻⁴
</span>
1st bottle is better bargain cause 1mg of aspirin its cheaper than in 2nd.
