Oops! You're dead right - got my equation the wrong way round. However, you are correct when you say [quote]USUALLY when the temperature drops density will increase and pressure will increase as a result
i.e. the increase in pressure you refer to is due to the increase in density rather then the reduction in temperature<hr></blockquote>in that each causes the next. Hence, generally, a decrease in temperature causes an increase in pressure - although not directly. Or alternatively, an increase in pressure causes an increase in pulse rate and stress! <img src="confused.gif" border="0">
