There is synthesis
decomposition
double displacement
single displacement
combustion
metathesis
so i guess you could say 6
Answer:
heat required in pan B is more than pan A
Explanation:
Heat required to raise the temperature of the substance is given by the formula

now we know that both pan contains same volume of water while the mass of pan is different
So here heat required to raise the temperature of water in Pan A is given as


Now similarly for other pan we have


So here by comparing the two equations we can say that heat required in pan B is more than pan A
500 ml = 0.5 liters. that's what i'm getting
hope it helps
