Why are hypotheses and theories are always tentative explanations?

1 answer:

8 0

Hypotheses and theories are based on observations and expectations, but can not, or have yet to, stand up to rigorous testing of experimentation and observation. Until a hypothesis is tested, it cannot be considered a definitive fact. The same is true of a theory.
Typically a theory differs from a law in that it cannot be tested to be true all the time, and is based on observations that cannot yet be repeated and adjusted to test the theory's veracity.

The vaporization of Br2 from the liquid gas to the solid state requires 7.4 kcal/nil what is the triangleH for this process

SSSSS [86.1K]

The initial state of the compound Br2 is liquid. The final state is then solid. We know for certain that the liquid state has higher energy as compared to solid state. Due to this fact, Br2 must release energy to be in solid form. Therefore, the change in enthalpy is:

ΔH = -7.4 kcal/nil
