A flask holds 8.75 kg of a diaatomic ideal gas (mass number of the gas 82,8). If the gas changes temperature isochorically (constant volume) from temperature 348° C to 752° C, find the change in the internal energy of the gas, in kJ. A positive answer means the internal energy increased, a negative answer means the internal energy decreased. A flask holds 5.11 kg of a monatomic ideal gas (mass number 283). If the gas changes temperature isobarically (constant pressure)...

Question 3 1 pts A gas tank with a volume of 22.1 L contains 4.1 moles of an ideal gas. The initial pressure of the gas is 7.5x10° Pa. The gas is compressed to half its original volume while the pressure stays constant. What is the final temperature of the gas in K? (Note: 1 mº = 1000 L) [Note: if you need to enter a number in scientific notation, use 'e. For example, 1200 = 1.2e3 and 0.0012 =...

QUESTION 16 The Moon which has mass of about 7.35 1022 kilograms, and it orbits the Earth with an average orbital distance of 384,400 kilometers. Calculate the following for the Moon the magnitude of the average gravitational force exerted by the Earth on the Moon: A. Newtons (use scientific notation and round the coefficient to two decimals) the magnitude of the acceleration due to Earth's gravity at Moon's orbit B. m/s (use scientific notation and round the coefficient to two...

planet X is observed (mass-M kg) to execute a circular orbit around celestial object YY. If the length of one planet-X year is 180 Earth-days, and it takes 20 light-seconds for light (velocity of light=3x108 m/s) to travel from YY to planet X, what is the mass of celestial object YY? How do your numbers change if a) the mass of X is doubled, compared to what you just calculated? b) at the original radius, the length of one planet-X...

An asteroid of mass m is in a perfectly circular orbit of radius d about a planet of mass M. You may assume that M>>m so that M is completely stationary. a. Determine an expression for the orbital period of the asteroid. (I already completed this step. Answer is T=2pi(r^3/2)/sqrt(GM) b. The asteroid is suddenly stopped in its tracks and allowed to fall freely towards the planet. Determine the time it takes to collide with the planet (assumed to have...
