At a temperature of 280 K, the gas in a cylinder has a volume of 20.0 liters. If the volume of the gas is decreased to 10.0 liters, what must the temperature be for the gas pressure to remain constant? (1 point) 140 K 273 K 560 K 5,600 K
Weegy: Find: V" for P'=P" Assumption: gas is ideal Using Charles's Law (Law of Volumes), since P'=P", V' / T' = V" / T" V" = V"T' / V' V" = (20.0L-10.0L)(280K) / (20.0L) V" = 140K (More)

What physical property makes wax good for making sculpture molds?
Weegy: Malleability helps, but the key word in the question is "molds". Low melting point is what is important. User: At a temperature of 280 K, the gas in a cylinder has a volume of 20.0 liters. If the volume of the gas is decreased to 10.0 liters, what must the temperature be for the gas pressure to remain constant? (1 point) Weegy: Carving wax is a smooth, non-brittle wax designed for carving and/or machining. Although the formulas for most commercial waxes are proprietary, most suppliers will state that hard waxes are some blend of waxes and plastics. [ This family of waxes has a hardness and consistency of plastic or softer wood. They can be cut or carved with knives, files and rotary or machine tools. To illustrate the usefulness of this type of wax, if one were to get a candle, mount it on a lathe and feed a tool into it, the wax would slough off like butter, stick to the tool and make a mess. Hard wax, on the other hand, will machine more like soft aluminum, giving fine edges and a fine finish if worked properly. ] (More)
