<span>We assume
that the gas is an ideal gas. Then, we can use the ideal gas equation which is
expressed as PV = nRT. The number of moles is constant so the value of PV/T is equal to some constant. At another set of conditions, the constant is still the same. Calculations are as follows:</span>
P1V1/T1 = P2V2/T2
V2 = P1V1T2/T1P2
V2 = 0.4(21.7)(323) / 252 (2)
V2 = 5.56 L
Answer:
Plastic wrap is commonly made out of PVC (Polyvinylidene Chloride). In recent years other PVC alternatives have become more popular. The most popular option in recent years is LDPE (Low-Density Polyethylene) because it is considered to be safer for the body. The best management for plastic wrap would have to be by you taking plastic wrap to local retail stores where they collect plastic grocery bags for recycling. Any package that you see with the How2Recycle Store Drop-Off label can be recycled this way.
Human waste from excretion is probably classified as organic waste, since it comes from you and the food you eat. The best management for human excretion would probably be sewer pipes that lead into the sewage system that lead into other mainframes.
Wastewater is an odd typing since it contains human waste, food scraps, oils, soaps and chemicals. The best management for this would include physical water treatment, biological water treatment, chemical treatment, and sludge treatment.
Answer:
False
Explanation:
Due to the fact that all the organisms are connected in a chain, the energy flow would be affected and that would result in many organisms being deprived of energy they need and that creates a chain effect.
Answer AND Explanation:
The islands had different environments, and the organisms had adaptations that enabled the organism to live in those environments. The island had been inhabited by its own kind of species found nowhere else in the world. Darwin also noticed that considerable variation exists between members of the same species. Offspring vary from their parents and between themselves.
The formula for density is mass over volume. In this problem the mass is 700 kg and the volume is 649 m^3. Thus, you would divide 700 by 649 to get a density approximately equal to 1.079. Hope this helped :))
