11. The freezing point of a substance is equal to the melting point of the same substance. They're like twins who are always on the same temperature wavelength.
12. For most substances, the distance between particles is smallest when the substance exists as a solid, especially a crystalline solid. It's like they like being close and snuggly.
13. Viscosity is a measure of a fluid's resistance to flow. It's like the fluid is saying, "I'm not going anywhere, no matter how much you try to pour me."
14. The cohesive forces within the gas don't affect its behavior in a closed container. It's like the gas particles are all about partying together, no matter what the forces say.
15. Pascal's Principle can be applied to solids and liquids only. Sorry gases, maybe next time. It's like solids and liquids get all the attention while gases go unnoticed, poor fellas.

11. To determine whether the freezing point of a substance is greater than, less than, equal to, or unrelated to its melting point, you can look up the specific substance's properties. By referring to a reliable source such as a chemistry textbook or an online database, you can find the freezing and melting points of the substance in question. Comparing the given values will help you determine the relationship between the freezing and melting points.
12. The statement is asking about the condition in which the distance between particles is smallest for most substances. To answer this question, you need to understand the nature of different states of matter. By studying the behavior of substances in different states, you can determine that the distance between particles is smallest when the substance exists as a crystalline solid. This is because crystalline solids have a highly ordered arrangement of particles, resulting in the closest distance between them.
13. Viscosity is a measure of a fluid's resistance to flow. To understand this concept, you can consider how different fluids behave when trying to flow. By experimenting with various fluids, such as water, oil, and honey, one can observe that fluids with higher viscosities flow more slowly compared to those with lower viscosities. Viscosity is influenced by factors such as temperature and molecular structure, and it can be measured using instruments such as viscometers.
14. The question is asking which of the given factors does not affect the behavior of a gas in a closed container. To answer this question, you can analyze each factor and determine its influence on gas behavior. The number of particles and their average kinetic energy are important factors that determine the pressure and temperature of a gas. The size of the container can affect the behavior of a gas, as it can change factors such as pressure and volume. However, cohesive forces within the gas do not affect its behavior in a closed container. Cohesive forces refer to the attractive forces between molecules within a substance, but in a closed container, these forces do not significantly impact the overall behavior of the gas.
15. Pascal's Principle states that a change in pressure applied to a fluid is transmitted equally to all parts of the fluid. To understand how this principle can be applied, you can consider the nature of fluids and their ability to flow. Pascal's Principle applies to solids and liquids, making it applicable to both in terms of transmitting pressure. For example, the principle is evident in hydraulic systems, where pressure applied to a liquid can be used to create mechanical advantages, such as in hydraulic lifts or brakes. It does not apply to gases, as gases can be easily compressed, and their behavior differs from that of solids and liquids.
