An ice block of volume 4Pi/3 cm^3 is in an artificial satellite at O(degrees celcius).
When the entire ice block melts into water,then its surface area in cm^2 will be(Assuming densities of ice and water to be same):
a)(4Pi/3) ^3
b)2Pi
c)4Pi
d)(36Pi) ^1/3
Plz explain..
because of surface tension, surface area of liquid will be minimum. for given volume surface area is minimum for a sphere.
volume =4pi/3, therefore radius= 1cm, area=area of sphere of radius 1cm =4pi cm^2
