The energy that was released by the candy is calculates using the below formula
Q=Mc delta T
Q= heat energy
m= mass (500g)
C= specific heat capacity) = 4.18 j/g/c
delta t =change in temperature = 25- 21 = 4 c
Q= 500 g x 4.18 j/g/c x 4c = 8360 j
Answer:
RQS + PQS = 180 ------- sum of angles on a
straight line
(2x + 14) + (x + 16) = 180
2x + 14 x + 16 = 180
2x + x + 14 + 16 = 180
3x + 30 = 180
3x = 180 - 30
3x = 150
x = 150/3 = 50
