Question

As heat is added to a tube of gas, which is the most likely phase transition to occur in the tube? gas to plasma gas to liquid gas to solid gas to element

Answer 1

The correct answer would be the first option. When a gas heated, the phase transition that would most likely occur is from gas to plasma. Heating a gas may cause the gas molecules to ionize therefore turning it into a plasma in which it contains charged particles.

Answer 2

Answer: Option (a) is the correct answer.

Explanation:

Plasma is defined as an ionized gas that consists of positively charged ions and negatively charged electrons which are similar in number. In a plasma, molecules move rapidly due to high energy.

Therefore, when a gas is heated then it will gain more energy due to the phase transition. Hence, this phase transition will change gas into plasma.

Thus, we can conclude that as heat is added to a tube of gas, gas to plasma is the most likely phase transition to occur in the tube.
