If the volume increases from 1.00 m3 to 3.00 m3 and 12.5 kJ is transferred to the gas by heat, what are (a) the change in its internal energy and (b) its final temperature?arrow_forwardA container having a volume of 2.3 m3 holds 9 moles of helium gas at 192°C. If the helium behaves like an ideal gas, the average kinetic energy per molecule is (write your answer in joules times 1023, i.e. if the answer is 3.45 x 10-21 J, write it as 345 x 10-23, and enter only 345 as your answer).arrow_forward
- Buckminsterfullerene, C60, is a large molecule consisting of 60 carbon atoms connected to form a hollow sphere. The diameter of a C60 molecule is about 7 ✕ 10−10 m. It has been hypothesized that C60 molecules might be found in clouds of interstellar dust, which often contain interesting chemical compounds. The temperature of an interstellar dust cloud may be very low, around 3 K. Suppose you are planning to try to detect the presence of C60 in such a cold dust cloud by detecting photons emitted when molecules undergo transitions from one rotational energy state to another.Approximately, what is the highest-numbered rotational level from which you would expect to observe emissions?arrow_forwardA student foolishly attempts to stop a steel bar, of length L = 1 m and at a temperature of 20ºC, from thermally expanding by attaching it to a wooden support with a nail at each end. Steel's Young's modulus is Y = 1.1 × 1011 N/m2 and it's linear thermal expansion coefficient is α = 13 × 10-6 1/C. Randomized Variables Y = 1.1 × 1011 N/m2α = 13 × 10-6 1/C What is the volue of the stress, in pascals, that develops due to a rise of temprature to 21 C? Assuming the nails have a cross- sectional area of A= 10^-5 m^2 all of which is perpendicular to the stress force from the bar, what is the force acting on each due to that temperature rise?arrow_forwardThe temperature in a room is 24.1 °C.

Avogadro’s number is 6.02 × 1023 mol−1 and Boltzmann’s constant is 1.38 × 10−23 J/K. Answer in units of J What is the root mean square speed of a neon atom under such conditions?

A clock with a 100-cm pendulum is moved from a location where g = 980 cm/sec2 to a new location. This increases the period by dT = 0.001 sec. Find dg and estimate the value of g at the new location.arrow_forward
