Answer 1

Answer:

Hello mate

Explanation:

1. Water at a temperature of 273 K would just absorb heat energy to achieve room temperature. Thus, water at 273 K will absorb less environmental heat energy than ice at 273 K. Therefore ice at 273 K more effective in cooling than water at the same temperature.

2. LPG (Liquefied Petroleum Gas) and Oxygen gas are the two gases which are supplied in compressed form in houses and hospitals.

3. Dry ice is the solid form of carbon dioxide. It is used primarily as a cooling agent, but is also used in fog machines at theatres for dramatic effects. Its advantages include lower temperature than that of water ice and not leaving any residue.
