The XYZ company develops prototypes of thermal systems and seeks to reduce environmental impacts in the process. To improve the performance of the systems, engineers analyze the behavior of gas molecules inside a container. Given that a gas sample is composed of helium (He) molecules at (27 ºC) and 3 atm of absolute pressure, calculate the average velocity of the helium molecules in this sample. Use the following values: molar mass of helium (He) = 4 g/mol and universal gas constant (R) = 8.31 J/(mol·K).
a.
1372 m/s
b.
1164 m/s
c.
950 m/s
d.
1050 m/s
e.
1287 m/s

During an experiment in the laboratory, a group of students is working with a cylinder containing 1 mole of ideal monoatomic gas, initially at a temperature of 300 K and a volume of 0.025 m³. The gas is then subjected to an isothermal process, in which its volume is compressed to 0.0125 m³. Consider that the universal gas constant (R) is equal to 8.31 J/(mol.K) and that the Cp-Cv constant (specific heat at constant pressure minus specific heat at constant volume) is equal to R for an ideal monoatomic gas. a) Determine the initial internal energy of the gas, using the relationship between internal energy and temperature. b) Calculate the work done on the gas during the isothermal compression process. c) Considering the results of items a) and b), discuss whether there was a variation in the internal energy of the gas at the end of the isothermal compression process. Justify your answer.

A scientist is working on the design of an environmentally friendly air conditioning system, using an ideal gas as a refrigerant in a cylinder. During the testing phase, the scientist conducts experiments with the gas to observe its behavior and calculate the internal energy of the system. Considering that the internal energy (U) of an ideal gas is given by the formula U = (n/2) * R * T, where n is the number of moles of the gas, R is the ideal gas constant (8.31 J/mol K), and T is the absolute temperature of the gas in Kelvin: a) Calculate the internal energy of the gas inside the cylinder, knowing that the system contains 3 moles of gas and its temperature is 300 K. b) Explain the main idea behind an environmentally friendly air conditioning system. c) How can the use of digital technologies assist in estimating and supporting the construction of prototypes for this system?

João is conducting an experiment in his Physics laboratory to determine the local acceleration due to gravity using a simple pendulum. He sets up a pendulum with a mass attached to a string of length L and measures the time it takes for the pendulum to complete 15 oscillations. Using this time and the given information, calculate the local acceleration due to gravity (g). Given that the period T of a simple pendulum is T = 2π√(L/g): a) Determine the general expression to calculate 'g' using the period T and the length L; b) Calculate the acceleration due to gravity (g) if João measured a time of 30 seconds for the pendulum to complete 15 oscillations and the length L of the string was 2.5 meters; c) Discuss the importance of approximating the motion of the pendulum as simple harmonic motion and the limiting factors of this approximation.
