Answer:
The correct answer is - C27H36N2O10.
Explanation:
C27H36N2O10 is the chemical formula of polyurethane foam which is a linear polymer manufactured by reacting polyols and diisocyanates. Polyurethane foam is used as a thermal insulator.
It used as filling material for various walls such as partition walls inside your house, determines the maintenance of proper insulation. It is not an acidic material that will dissolve easily. It is used not just as wall-filling material but also for sealer and filling in furniture and carpets.
Answer:
20L
Explanation:
The following data were obtained from the question:
Initial volume (V1) = 10L
Initial Temperature (T1) = stp = 273K
Final temperature (T2) = 546K
Final volume (V2) =..?
The new volume of the gas can be obtained by using the Charles' law equation as shown below:
V1/T1 = V2/T2
10/273 = V2/546
Cross multiply to express in linear form
273 x V2 = 10 x 546
Divide both side by 273
V2 = (10 x 546) / 273
V2 = 20L
Therefore, the new volume of the gas is 20L.
