[5.4]. When heat is transferred from the surroundings to the system, q has a positive value. Likewise, when work is done on the system by the surroundings, w has a positive value (Figure 5.6). In other words, both the heat added to the system and the work done on the system increase its internal energy.onversely, both the heat lost by the system to the surroundings and the work done by the system on the surroundings have negative values; that is, they lower the internal energy of the system.

However, other tests may still be needed based on your symptoms. Some people with autoimmune diseases may test negative for ANA but positive for other antibodies. A positive ANA test means that you have high levels of ANA in your blood. A positive ANA test is usually reported as both a ratio (called a titer) and a pattern, such as smooth or speckled. Certain diseases are more likely to have certain patterns. The higher the titer the more likely the result is a âtrue positiveâ result, meaning you have significant antinuclear antibodies and an autoimmune disease. However, a positive result doesnât always mean that you have an autoimmune disease.
