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.

kykrilka [37]

B. Argon's vibrational energy is not excited by infrared radiation.

Explanation:

The property of carbon dioxide to get excited by infrared electromagnetic radiation is what qualifies it as a greenhouse gas. When infrared from the earth's surface is reflecting back to space, some of the radiation is absorbed and remitted by the carbon-dioxide molecules in the atmosphere. This causes a phenomenon called greenhouse effect that causes the atmosphere to be relatively warmer. The more the carbon dioxide molecules the more the greenhouse effect.
