A copper cup of 100 \[c{m^3}\] capacity is fully filled with glycerine at \[{25^o}C\] . What is the required temperature to spill out the 2.52 \[c{m^3}\] of glycerine from the cup? (The coefficient of volume expansion of glycerine is \[5.1 \times {10^{ - 4}}/{C^o}\] and the coefficient of linear expansion of copper is \[17 \times {10^{ - 6}}/{C^o}\] ).
