Question #1189

How can we evaluate the change in density between the given pressure when melting point of tin at pressure of 1 bar is 505K, but increases to 508.4K at 1000 bar?

please tel the steps and formulas used.

Expert's answer

According the formula

PV/T = const

So, we get

103x10^{3} Pa *V_{1} / 505K = 103x10^{6} Pa *V_{2} / 508.4 K

But the mass of tin is const, so density is greater inV_{1}/V_{2}.

V_{1}/V_{2} = 103,000/505 * 508.4 / 103,000,00 = 1.006*10^{-3}

Answer: it’s greater in 1.006*10^{-3}

PV/T = const

So, we get

103x10

But the mass of tin is const, so density is greater inV

V

Answer: it’s greater in 1.006*10
