Step-by-step explanation:
when solid melts to become liquid there is no change in temperature them what is the use of heat energy supplied
given that a12 = 37 ,d = 3
As, an = a + ( n - 1 ) d
a12 = a + ( 12 - 1 ) 3
37 = a + 33
a = 4
Sn = n/2 [ a + an ]
Sn = 12 / 2 [ 4 + 37 ]
Sn = 6(41)
Sn = 246 ANS❤️
