If you want to find out the density of an object, what two things do you need to know about it?

How do I determine density? Density is not something that is directly measured. Typically if you want to know the density of something you will weigh it and then measure its volume.

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..
