1.According to the kinetic theory‚ both the particles in gases and the particles in liquids have kinetic energy. This energy allows the particles in gases and liquids to flow past one another‚ as shown in Figure 13.5. Substances that can flow are referred to as fluids. The ability of gases and liquids to flow allows them to conform to the shape of their containers. Figure 13.5 Both liquids and gases can flow. The liquid on the left is colored water. The gas on the right is bromine vapor. If a

They are amazing parents and have raised some astonishing children‚ at least in my opinion.

The increasing pressure of expectations on young people in school now seems to have consequences for their health. The school can be dangerous‚ because many young people can’t handle their parent’s requirements. Today many parents have high expectations to their children. Not every child can handle a lot of pressure. Parents have no idea how something they say can affect their children‚ especially when they say that
