(a)What conditions are represented by the abbreviation STP? (b)What is the molar volume of an ideal gas at STP? (c) Room temperature is often assumed to be 25°C. Calculate the molar volume of an ideal gas at 25°C and 1 atm pressure.
Chemistry Skills and Reasoning 1 Week 11 Chapter 14: Liquids and Solids - Remember: gases are low density, highly compressible, and ﬁll the container - Solids are high density, slightly compressible, and rigid (keeps their shape) - Changes of state are physical changes: no chemical bonds are broken - When a substance changes from solid to liquid to gas, the molecules remain intact - The changes in state are due to change in the forces among molecules rather than in those within the molecules - Solid to liquid: as energy is added, the motions of the molecules increase, and they eventually achieve the greater movement and disorder characteristic of a liquid - Liquid to gas: as more energy is added, the
