When the size of an object were scaled up by a factor of 10 while retaining its present proportions, how would it affect the object's strength-to-weight ratio, and its surface area-to-volume ratio?

Determine ∆S for the phase change of 2.52 moles of water from liquid to solid at 0.0 °C. (∆H = -6.01 kJ/mol)
