19. For her school science project Shreya performed an experiment in science lab. She prepared

a report where she got different values of freezing points of some gases and her report was

characterized into two categories that was degree Celsius and degree fahrenheit. The given

table shows the freezing points in (°F) of different gases at sea level.

Gases Freezing point at sea level(°F) Freezing point at sea

level(°C)

Hydrogen -435

Krypton -251

Oxygen -369

Helium -458

Argon -309

Q.1 Using the above table, list the gases in decreasing order according to their freezing point at

sea level.

Q.2 Convert each into (°C ) using the relation. C=5/9 ( F-32).

Q.3 Which one of the gas has lowest temperature.​
