Stone can undergo a process called sublimation, where it transitions directly from a solid to a gas without passing through a liquid state. However, this process is typically only observed under extreme conditions such as high temperatures and low pressures. On the other hand, plastic does not typically sublime as it tends to melt and degrade when exposed to high temperatures. **

Iodine sublimes at room temperature because its vapor pressure is high enough to allow it to transition directly from a solid to a gas without passing through the liquid phase. This is due to the weak intermolecular forces between iodine molecules, which allows them to easily break free from the solid lattice and transition into the gas phase. As a result, iodine can sublime at room temperature without needing to be heated to its melting point. **

Booking flights and hotels separately for a vacation can sometimes save money, especially if you are able to find good deals on each individually. It also allows for more flexibility in terms of choosing different airlines and accommodations that suit your preferences. However, booking a package deal can sometimes offer convenience and cost savings, as well as added benefits like transportation and activities included in the package. Ultimately, the decision depends on your budget, preferences, and the specific deals available at the time of booking. **
