[7g-189] Which of the following is NOT true concerning the condition of heat energy in solids? (particles can mean atoms, ions or molecules)
1. when a solid is heated, the particles vibrate faster with greater kinetic energy
2. higher kinetic energy particles, vibrating faster, transfer energy to neighbouring particles of lesser vibrational kinetic energy
3. thermal conduction of heat energy continues until all the particles in a system attain the same temperature with the same average kinetic energy
4. the lower the temperature, the faster the particles vibrate with less vibrational energy
Which of the following statements is NOT true about the state changes between the liquid and gaseous states of matter of a substance? [7g-190]
1. Evaporation means molecules change from a liquid state to a gaseous state only at a fixed temperature.
2. Boiling means molecules change from a liquid state to a gaseous state, both at the surface and in the bulk liquid
3. Condensation can take place at range of temperature between above the melting point and below the boiling point.
4. Boiling takes place at a fixed temperature at a given pressure.
Which of the following statements is NOT true about the state changes between the liquid and gaseous states of matter of a substance? [7g-191]
1. Evaporation means molecules change from a liquid state to a gaseous state, but only at a liquid surface over a range of temperature from above the melting point to below the boiling point.
2. Boiling means molecules change from a liquid state to a gaseous state, but only from the surface over a range of temperatures.
3. Condensation can take place at range of temperature between above the melting point and below the boiling point.
4. Boiling takes place at a fixed temperature at a given pressure.
Which of the following statements is NOT true about the state changes between the liquid and gaseous states of matter of a substance? [7g-192]
1. Evaporation means molecules change from a liquid state to a gaseous state, but only at a liquid surface over a range of temperature from above the melting point to below the boiling point.
2. Boiling means molecules change from a liquid state to a gaseous state, both at the surface and in the bulk liquid
3. Condensation can only take place at a temperature just below the boiling point.
4. Boiling takes place at a fixed temperature at a given pressure.
Which of the following statements is NOT true about the state changes between the liquid and gaseous states of matter of a substance? [7g-193]
1. Evaporation means molecules change from a liquid state to a gaseous state, but only at a liquid surface over a range of temperature from the melting point to the boiling point.
2. Boiling means molecules change from a liquid state to a gaseous state, both at the surface and in the bulk liquid
3. Condensation can take place at range of temperature between above the melting point and below the boiling point.
4. Boiling takes place over a range of temperatures as the liquid is heated up.
