which level are u on now?
By the second law of thermodynamics:
Heat can not spontaneously flow from cold regions to hot regions without external work being performed on a system.
Heat transfer is the passage of thermal energy from a hot ( t B = 80° C ) to a colder body ( t A = 40° C ).
Answer: B ) Heat flows from object B to object A.
The answer is C because there are 22 oxygen atoms on the product side so to balance the equation the coefficient needed is 11
The answer would be Force
