Answer:

1125 calories

Explanation:

Required Heat to raise the given temperature by #Delta theta# is given by:
#H = m*c*Delta theta#, where, m is the mass, c is the specific heat capacity of the material and #Delta theta# is change in temperature. Using for ice c = 0.5 Cal/g/°C,
We get,
#H=150*0.5*(-15-(-30)#
#H=75*15=1125 cal#
