Ques: Answer the following question given this paragraph: A homogeneous mixture is a mixture in which the composition is uniform throughout the mixture. The salt water described above is homogeneous because the dissolved salt is evenly distributed throughout the entire salt water sample. Often it is easy to confuse a homogeneous mixture with a pure substance because they are both uniform. The difference is that the composition of the substance is always the same. The amount of salt in the salt water can vary from one sample to another. All solutions would be considered homogeneous because the dissolved material is present in the same amount throughout the solution. Q: What is the most important characteristic of a homogeneous mixture? Choices: - very reactive - high density - nonreactive - uniform composition throughout A:
Ans: uniform composition throughout

Ques: Answer the following question given this paragraph: Warmer, lighter air is more buoyant than the cooler air above it. So the warm air rises. The cooler air is denser than the air beneath it. So it sinks down. This is convection: warm air rises, and cool air sinks. Warm fluids can undergo convection as well. This is described in the chapter Plate Tectonics . Q: What process is at work when warm air or water rises, and cool air or water sinks? Choices: - evaporation - radiation - moisture - convection A:
Ans:
convection
