H S G Low temperature and High temperature.
When H is negative and S positive and G negative there will be spontaneous low temperature and spontaneous high temperature. When H is negative, and S is negative and temperature dependent then the low temperature will be spontaneous and high temperature will be non-spontaneous. When H is positive and S is positive then the temperature dependent and low temperature are non-spontaneous and high temperature will be spontaneous. When H will be positive and S is negative then G will be positive, the low temperature will be non-spontaneous and high temperature will also be non-spontaneous.

Answer and Explanation:
Observation is when you take a look at something really closely like examining the object.
For example:
You watch an interesting bird that you've never seen in you're life and decided to study it's feasters. That's called "Observing'.
Answer:
When you sit on a plane for 6 hours without moving, blood accumulates in your veins, and the moment you get up, gravitational forces affect venous return, cardiac output, blood pressure, and venous pressure. That way, when you're sitting on a plane, the gravitational force is the same at the upper and lower extremities, such as the chest, abdomen, and legs, causing venous blood pressure and volume to be evenly distributed throughout the body. However, when one gets up, one becomes dizzy because of abnormal regulation of blood pressure. This is because gravity causes blood to accumulate in the lower extremities (veins of the legs and trunk). This lowers the blood pressure and the blood that the heart pumps. By causing blood to accumulate in the lower extremities, and as venous compliance increases, the veins expand with blood that causes the volume of blood to shift in the veins. This increases the volume and venous pressure in the lower extremities when standing. And the volume of thoracic venous blood is less and less central venous pressure. This leads to a decline in stroke volume. Cardiac output and mean arterial pressure also decrease as left ventricular stroke volume decreases, reducing pulmonary venous return. Decreased standing blood pressure, referred to as orthostatic or postural hypotension. Thus, lowering blood pressure decreases cerebral blood flow, which means less range of blood in the brain causing dizziness.
