Re: Ice Spires.

[Herbert H Gottlieb <herbgottlieb@JUNO.COM>]

According to the Handbok of Chemistry and Phyiscs (Page F5)
water is densest at a temperature of 4 C. It not only expands when
heated above this temperature but it also expands CONTINUOUSLY as it is
cooled to  FROM +4 TO -20 C.

Could this help explain the pressure changes that do (or do not)
occur within an ice cube as the liquid interior crystallizes??
