If a sample of carbon dioxide is at − 60.0 ∘C and 0.50 atm and warm to 30.0 ∘C and 0.50 atm, then there will be no phase transition in the sample is a True statement.
Phase Transition:
- The three main states of matter are Solid, Liquid, and gas. A phase transition occurs from one state of matter to another when energy is supplied or cut.
- When energy is supplied to the molecules, solid converts to liquid, and liquid converts to gas.
- Then, the energy increases the speed of the molecules, the density decreases and phase transition takes place.
- On the other hand, when the supply of energy is stopped from the molecules, the gas turns to liquid, and liquid converts to solid. Both the temperature and pressure are in the same phase.
Therefore, there will be no phase transition in the sample. Hence, it is a true statement.

Given that the equipment is stationary, we should remove particles (such as food and soil) from around the equipment.
This step ensures that large particles are removed and do not hinder the remaining process of cleaning. After doing so, the next step is to remove the removable parts of the machinery. After this has been done, the cleaning steps may be undertaken.
