Answer C
When the temperature of water decreases, the hydrogen bonds are formed and release a considerable amount of energy. Water has the highest specific heat capacity of any liquid. Specific heat is defined as the amount of heat one gram of a substance must absorb or lose to change its temperature by one degree Celsius
Since the square root of 13 is something really weird (3.6055 something) and does not have a clear end or repeats, it is irrational. Solve for the number before assuming anything
Answer:
Step-by-step explanation:
1st one
There is 2n+150 litres of oil in total. We have to divide this oil into 3 equal parts which will be named Tank A, Tank B, Tank C.
C was empty at first, then it was delivered 500 litres in total. So if every tank was supposed to have one thirds of it, that means one thirds of the oil equals to 500 litres.
All of the oil would be 500x3=1500 litres
2n+150 was the formula to our total litre count, so if we make a connection between them, we can solve this question for the value of n.
2n+150=1500
2n=1350
n=675
The answer is A and here is how I solved it
