The Nature of Dark Matter We observe the universe around us through many scientific means. However it is through the electromagnetic spectrum‚ that is everything from radio waves to gamma waves‚ that we learn about the objects in our world and beyond. However we can also learn about our universe through indirect means‚ such as the effect of gravity on light as well as larger objects like our galaxy. In fact it is this indirect method of observation that has led us to the discovery of extra-solar

Gender Typing Gender typing has many effects on a child and its attitudes towards gender later in life. If children are taught something while being brought up and observing‚ chances are they’re going to take that with them for the rest of their life and be biased towards things and how they perceive others. It could also have a negative impact on what children believe what’s acceptable; things to play with such as different toys and colors for different sexes. “According to social learning

States of matter are the distinct forms that different phases of matter take on. Historically‚ the distinction is made based on qualitative differences in bulk properties. Solid is the state in which matter maintains a fixed volume and shape; liquid is the state in which matter maintains a fixed volume but adapts to the shape of its container; and gas is the state in which matter expands to occupy whatever volume is available. This diagram shows the nomenclature for the different phase transitions

CHAPTER 5 STATES OF MATTER INTERMOLECULAR FORCES Intermolecular forces are the forces of attraction and repulsion between interacting particles (atoms and molecules). Attractive intermolecular forces are known as van der Waals forces. van der Waals forces include dispersion forces or London forces‚ dipole-dipole forces‚ and dipole-induced dipole forces. A particularly strong type of dipole-dipole interaction is hydrogen bonding. Dispersion Forces or London Forces Observed between non-polar molecules
