Question

Is there any compound or element whose liquid state is denser than its solid state at any temperature (other than water)?

Answer 1

well water is most dense at 4'c

gallium - 5.91 (solid) vs 6.095 (liquid)
bismuth - 9.78 (solid) vs 10.05 (liquid)
germanium - 5.323 (solid) vs 5.60 (liquid)
silicon - 2.3290 (solid) vs 2.57 (liquid)
water - 0.917 (solid) vs 0.998 (liquid)

acetic acid - 1.266 (solid) vs 1.049 (liquid)

Answer 2

thnx but what are the units for the numbers used?

Answer 3

its g/cc

Answer 4

thnx
would u answer another question i have in mind although its not related to this question??

Answer 5

anything agar mujhe nahi pata hoga to google haina tujhe tera answer mil jayega

Answer 6

If the momentum p=mv is calculated for an object which mass is taken into account (rest mass or mass at the given velocity according to relativity)?

Answer 7

this momentum is used for objects at very low velocity. . .
rest mass of objects moving with velocity less than of light have relative momentum that is \[E=\sqrt{p ^{2 }v ^{2}+m _{o}^{2}c ^{2}v ^{2}}\]

Answer 8

what's E ?

Answer 9

its energy of particle relative kinetic energy. . .

Answer 10

thnx i got it now

Answer 11

aur koi question bhai??
