[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. The relationship between the signs of q and w and the sign of E is presented in Table 5.1.
Best Answer: I don't know what a QL test is. Maybe qualitative ? (as opposed to quantitative) That just means you get a yes or a no answer and not a quantitative answer as far as how much HCG is detected (anything over 25 IU is positive for pregnancy). I think reference range is just the standard values for negative and for positive. If the results came back negative, then that means you are not pregnant. Or, you tested too early. To avoid a false negative, do not test any sooner than when your period is due. This goes for a blood test as well as for a urine test.
