What is theweight of 2 m 3 of helium at 1 atm and 20 ° C?( a ) 3.3 N, ( b ) 6.5 N, ( c ) 11.8 N, ( d ) 23.5 N, ( e ) 94.2 NAn perfect gas of a specific composition Molar weight is 25 grams per mole and specific heat is 3 grams per mole. Y is initially at 200kPa and 2m3 in volume. Heat transmission resulted in a twofold increase in volume. Calculate how much heat was transferred if it was subjected to a process defined by 'n=1', "n=Cp/Cv," or "n=2."A tentative rule was given about tipping in Testing Experiment Table 8.4, where if a vertical line passing through the object's center of mass is within the object's area of support the object does not tip. According to the rule, the full box of crackers in the following experiment, which has a width of 13 cm and a height of 20 cm, was seen to tip at an angle of: θc=tan−1(13 cm/20 cm)=33∘θ According to the rule, at what angle will a box with the left half filled with crackers begin to tip? Assume the box is light-weight and that the contents remain in the configuration in
- The following thermodynamic potential functions H (enthalpy), A (Helmholtz function), G (Gibbs function) and U (internal energy) are connected by a system known as Maxwell's relations. Explain what is meant by Maxwell relations. If you know that dU = – P dV + T dS (P is pressure, V is volume, S is entropy and T is temperature), use the Legendre differential transformation to prove that dA = – P dV – S dT. In your own words, explain the role and importance of functions A and U.The Born–Oppenheimer principle [1] is often said to be a prerequisite for the concept of a PES. Yet the idea of a PES [2] predates the Born–Oppenheimer principle (1927), DiscussComplete the following table for refrigerant-134a. Show your work and explain how you got your values.

She finds thatthe rate of cooling for one liquid can be modelled by the equation:y = 48 × 0.99t(0 ≤ t ≤ 80)where y is the temperature of the liquid in degrees Celsius and t is thetime in minutes.(i) State whether the type of reduction for this model is linear orexponential. Describe how reduction rate differs between linear andexponential functions. (ii) Calculate the temperature when t = 20.
