A substance that exists as both a liquid and a solid at the same time is called a "solid-liquid mixture" or a "suspension." This occurs when a solid material is evenly dispersed throughout a liquid, creating a two-phase system.
When a solid is heated and changes to a liquid, the phase change is called melting.
A semifluid is a substance that has properties of both a liquid and a solid. It flows like a liquid but also exhibits some degree of resistance to flow, similar to a solid. Examples include toothpaste and mayonnaise.
Cytoplasm is a semi-fluid substance that resides inside a cell. It is neither solid, liquid, nor gas, but rather a gel-like substance that contains various organelles and dissolved molecules necessary for cellular functions.
A phase change from solid directly to gas is called sublimation. A common example of sublimation is that of dry ice (solid carbon dioxide).
A substance that exists as both a liquid and a solid at the same time is called a "solid-liquid mixture" or a "suspension." This occurs when a solid material is evenly dispersed throughout a liquid, creating a two-phase system.
When a substance is melting, there is equilibrium between the solid and liquid state, meaning it is both a solid and a liquid.

The freezing point of a liquid is the temperature at which it solidifies into a solid, while the melting point of a solid is the temperature at which it changes into a liquid. These two temperatures are the same because at both points, the substance is in equilibrium between its solid and liquid form, with no net change in phase occurring.
Both! The physical state of a substance can go straight from gas to solid, or can heat from solid to liquid and then to gas. The process a solid undertakes when it goes straight to its gas state from a solid state without first turning liquid is called sublimation.
The state between a solid and a liquid is called a semi-solid or colloidal state. In this state, the substance exhibits properties of both solids and liquids, such as the ability to flow like a liquid while maintaining some structural integrity like a solid. Examples include gels or colloids.
Both indicate the temperature at which the solid and liquid states of a substance are in equilibrium.
Both indicate the temperature at which the solid and liquid states of a substance are in equilibrium.
Both indicate the temperature at which the solid and liquid states of a substance are in equilibrium.
One example of a substance that can exist as both a liquid and a solid is honey. At room temperature, honey is a thick liquid, but if cooled below its freezing point, it can solidify into a semi-solid state.
