Homework Answers
Solid = particles are close to each other and do not move relative to each other, definite volume and definite shape
Liquid = particles are close together and can move past each other, definite volume, no definite shape
Gas = No definite volume, no definite shape, particles may be far apart and move randomly

Determine whether each statement describes the solid state, liquid state, or gaseous state. Answer Bank gas This state is characterized by the lowest density of the three states. solid liquid liquid This state is characterized by an indefinite shape and high density. solid Temperature changes significantly influence the volume of this state. gas Pressure changes influence the volume of this state more than the other two states. solid In this state, constituent particles are less free to move around than...

Phase changes are transitions between solid, liquid, and gas phases. For example, ice melting is an example of a phase change from a solid (ice) to a liquid (water). Phase changes involve changes in energy. Which of the statements regarding phase changes are true? Sublimation is the conversion of a gas to a solid. Freezing is the conversion of a gas to a liquid. Deposition is the conversion of a gas to a solid. Melting is the conversion of a...

4. The other phase change that can happen is liquid to gas. Similar to the phase change of solid to liquid, the temperature of the system does not change. All of the energy goes into the phase change. Only now instead of the latent heat of fusion, we have the latent heat of vaporization: Q = mly How much heat must be added to 3.8 kg (1 gallon) of water for half of it to be changed into gas? The...

Substance X is known to exist at 1atm in the solid, liquid, or vapor phase, depending on the temperature. Additionally, the values of these other properties of Xhave been determined.: melting point 15.°C enthalpy of fusion 8.00/kJmol density 2.00/gcm3 (solid) 1.60/gmL (liquid) boiling point 60.°C enthalpy of vaporization 31.00/kJmol heat capacity 36.·J·K−1mol−1 (solid) 29.·J·K−1mol−1 (liquid) 55.·J·K−1mol−1 (vapor) You may also assume X behaves as an ideal gas in the vapor phase. Suppose a small sample of X at −20°C is...
