What is the specific heat of a substance if 1560 cal are required to raise the temperature of a 312-g sample by 15°c? a) 0.033 cal/g°c b) 0.33 cal/g°c c) 0.99 cal/g°c d) 1.33 cal/g°c

The specific heat capacity  the substance is calculated  using  the below formula

Q(heat) = Mc delta T
Q =1560  cal
m(mass) 312 g
delta T (change in temperature ) = 15 c
C= specific heat capacity=?

by making c the subject of the formula 
c=Q/m delta T
= 1560  cal/ 312g x 15 c = 0.33 cal/g/c (answer B)

1.from liquid state to gaseous state is evaporation 3.solid to liquid is melting 5. solid to gaseous state is sublimation 6. gas to solid state is decomposition 7. a change of state is known as the states of matters
